Putting a good aftermarket muffler is a great mod for our V6's... Free up about 10RWHP... a bit more if you go with the MRT... now of course when I say "good" I mean NOT A FART CAN! LOL! As far as gas mileage in theory it should improve... but the fact is the new exhaust sounds tends to make your right foot heavier... which does decrease your milage! LOL!

any suggestions on a good aftermarket muffler??

None of the s197 v6 specific mufflers are ricey at all IMO....it's when you get to the universal style ones you'll find rice.

I love my Flowmaster American Thunder.

Sounds great and looks awesome. It is a black muffler with a chrome tip so it blends in nicely under the car.

I have heard good things about Flowmaster, MRT, Mangaflow, Borla, JBA, GT takeoffs and others I cant think of.

And no, it is not ricey if you get a good one, it will actually make your car more mean sounding, might even trick people into thinking you have a V-8

Cheers,

Mufflers will help a little bit with gas mileage and power. Don't expect amazing results, but it does help. On my 04 Crossfire I noticed about a 1.5mpg increase on highway with just a muffler, but on the street it dropped a lot because the right foot definately gained some weight.

not ricey at all, i get compliments all the time and i did feel a little power from my mrt. The gas milage depends on the driver. I stayed the exact same on milage, but before i got the muffler i was still getting used to driving a stick. I drive alot harder now because of the sound (especially past the all girls school on my way home ;) ).

Yep... the extra performance I felt when we put in the MRT made me think my butt dyno was seriously out of calibration! But we but the Mistress on Lidio's dyno and confirmed that gain! LOL!

BTW... stopped to pick up my step-daughters proofs from the photo studio... noticed the photographer was outside... went in side to pick up the proof.. he comes in and says "That car is absolutely beautiful! And the sound! I heard you pulling in... that sound was incredible! It didn't sound like a car... it was awesome!" Not quite sure what he meant by it not sounding like a car... but he was sooooo geeked about it I just let him go on! LOL!

gotta love the mrt. I was in birmingham (where most of the teenagers in my area hang out on weekends) parking my car in the parking structure to go to a movie and my friend says, "dude" and points out the window and these three girls are staring at us from about 50 feet away and when we get out one of em says, "nice car." So we walk over to talk to em and it was a girl i had known in elementary school! Well she had quite obviously "grown up" ALOT and we talked for a while and then we decided we were all going to hang out the next day (saturday). So my friend and i go over to one of her friends' house and we hung out the whole night watching movies and doing other **** and then she asked me if i could take her for a ride in my car...yea i took her for a ride... ;)



i LOVE my car. The muffler just makes it more noticable and beleive me, thats a good thing.

Hey!!
Been following your mods for a while, including MM article!

One question about the MRT, how is it cruising as far as interior noise and more importantly (to me anyway) drone is concerned?

I once made the big mistake of removing the resonator on my Caprice Chevy small block ( in the rear) and the drone was horrid so I was cured of that little trick[:@]

So how is the MRT for just plain around town and crusing?

FWIW I am less undecided and I think the V6 2007 Pony/IUP is in my future.
No 2006 left around here except in sliver and I don't like that color (no offense to anyone because I DO like green[8D] )

I'm looking at maybe the Ford Racing/MRT/Flowmaster, keeping it single exhaust, an Xcal and CAI and that's about it for me.
I also need an automatic for my better half to be able to drive it.

Advice?

you're not serious are you? You're telling me that adding a muffler (not even a catback system) by itself will add 12-13 flywheel horsepower? Do you have Dyno Slips?? And I mean both with a Baseline (stock) car and then with just the muffler added (as in no other mods, no CAI or anything else)?

I can understand a muffler adding 10rwhp if there are other mods but just a muffler on a stock car...? :eek:

Add: Okay I read your website, you are definitely NOT STOCK..so 10rwhp is not out of line. But for a stock car you MAY get like 3-4 RWHP for just a muffler..not 10.

They are only Ricey if they are "Fart Cans". Flowmasters or similar are fine.

if im not mistaken his car was almost stock if not completely stock when he did that dyno.

I'm too busy at work to go back and look but If so then he probably did a TUNE and Muffler. 10RWHP for just a muffler...maybe on a vette or Mustang GT (since there are two mufflers on there) Not a V6 tho.

actually the muffler is the most restrictive part of our exhaust and you will only gain 2-3 hp by going duals. Beleive me there has been ALOT of discussion on this.

plus the mrt is completely straight thru. You can look right thru it.

No not ricey at all..... Just go with any one of the aftermarket brands out there and you should be alright. There is many that make them for our car. IMO if I had to do it over again ( I went with the JBA) I'd get ford racing or flowmaster.....JMO though.

it's all in preference. If you like the stock sound, don't spend the money. There are other mods that will give you more power per dollar. If you want ALOT louder, go mrt. If you want slightly louder, id say magnaflow. I think jba is a bit louder than magnaflow, and same with the borla/ford racing. Whatever you get, i think you will be happy with the results.

Ok... you have every right to be skeptical! Believe me I was too... So... I will try to offer you some solid proof...

Justin at VMP tuning in Florida did some dyno testing on his wife's car. He showed and 11RWHP gain simply by removing the muffler! He put on a GT take-off muffler and it went from 11RWHP gain to a 10RWHP. So that goes to show just how restrictive the V6 muffler is! Now I had a Magnaflow single axleback... We never dyno'd it seperately BUT we figured it was good for about 10RWHP, which just so happens to be what Justin found with a GT take off! So again the stock muffler suck.... good aftermarket or even GT take off is good for 10RWHP... I know it's hard to believe... so here is a link to Justin's write-up:

http://www.v6power.net/vb/showthread.php?t=25551

Now the thing about Justin's right up is it also included a CAI which might have helped...

Now here's another example that is more to what you are asking. Check out Lidio from Alternative Auto's write on on the V6. This was a completely STOCK V6 automatic... Unfortunately he didn't publish dyno sheet for it but here's what he says:

"Although it’s not shown here on a dyno graph we also tested a better cat-back exhaust system for the V-6 Mustang and found an unbelievable 10 horsepower at the rear wheels from about 4000 rpm up. The exhaust system with our tune ended up producing 190 RWHP. I must say that at 190 RWHP coupled to the new 5-speed automatic, this new V-6 Mustang feels very impressive all around." (http://www.alternativeauto.com/prodserv/v6_05mustang_tune.html)

Even Lidio was surprised at the 10RWHP gain! So there you have 2 very well respected shops saying they seen 10RWHP with with a new muffler! And like I said while we never did an actually test on my Magnaflow we figured it added about 10RWHP....

Now... enter the MRT Aero-Turbine. When we put it on I could not believe the difference in performance it made! I was so impressed I paid for dyno time at Alternative Auto to verify that my butt dyno wasn't out of whack! Now we did not have the luxury of back to back testing... however we did our best to do as fair of a comparison as possible! We made a number of pulls with the MRT and compared them to a number of pulls we had with the Magnaflow.... Again, I understand it is not scientific... BUT in my mind it was a very fair comparison... The MRT beat the Magnaflow hands down! The impressive part is at just over 5500 RPM... notice how the Magaflow's HP drops while the MRT Aero-Turbine doesn't drop as fast! That is the science behind the Aero-Turbine.. LOL! Here' the MRT vs Magnaflow:

http://www.tammyandjohn.com/Mustang/Screaming/Images/mrtdyno2.jpg

Trust me... I thought the Aero-Turbine mumbo-jumbo sound too good to be true... I was a big time skeptic... but after the first couple of romps on the gas pedal I was a believer! LOL!

Well...... yes, some people can't stand the MRT at cruising speeds.... some think it's ok... some turn up the stereo... LOL! As for me with my 4.10's my cruising RPMS are a tad bit higher than most so i don't have the drone... Personally I love the sound of the MRT! If you get the MRT and decide it is to much you can add a resonator... I heard one for the first time last week... I think it would solve any issue you have with drone...

For automatics.... you might want to consider Alternative Auto (www.alternativeauto.com) for an x-cal2/C&L cai combo...

getting a muffler will not do anything to your gas milage. i have a muffler and an intake, my gas is only for the better when i drive ok. go get a flowmaster or something, they make a bolt on no welding or fabrication needed.

WTF? This ricey thing is getting way out of hand, LOL! I muffler is ricey, ROFL! Unless its ones of those huge universal ones from ebay.

I have Flowmaster 40 Series True dual w/ H-pipe and it sounds GREAT! If you're going to stick with the single exhaust deffinitly go with MRT, those mufflers on a single exhaust sound AWESOME! Very Loud, very throaty and deffinitly muscular!

Oh one other thing, if you get a true dual with no H-pipe or X-pipe then it does actually sound somewhat ricey...

whats a good website for MRT

www.MRT-direct.com They have a V6 specific setup with mounts, clamp, and tip. Perfect for people who don't want to have a shop install and do it yourself. It's what I got and never could be happier. Drone is in all honestly very minimal, the muffler most of the time is quite mellow. I think people complaining about it are babies :D

When you start the car and hear it growl you'll never look back.

The aftermarkets mufflers I have heard make the V6 sound "throaty." Nothing like that annoying "ricey" "fart-pipe four" sound.

Hopefully I will be upgrading my muffler situation soon. I'm still trying to decide which direction to go.

I say it's ricey. In fact, I think I'm going to leave my CAI off, I'm liking how quiet the car is with the stock airbox, and frankly, I cant feel the extra HP its supposed to be giving me.

To each their own, though. I just think it should be seen and not heard.

JUST GOT MAGANFLOWS AND INSTALLED THEM TODAY, AND THEY SOUND GREAT.

Flowmasters with H-pipe. Not ricey at all. Sounds great. A bit better performance overall. Don't get a plain "muffler"???

My experience with the C&L intake has been different from most on the forum. I do not hear the intake at all. I hear the GT take-off muffler, but not the intake (I'm a vert, so the car sounds differently). Stratjakt, I don't remember your set-up, but an aftermarket tune is designed to be used with a CAI, so your car may not perform well with the stock airbox (unless the tuner set it up to run with the stock intake).

I love the dual flows set-up. It doesn't sound ricey at all and it's well worth the money.

^ Yup, Americanmade, thats what I'm talking about. I have that set up- dual Flowmasters with H-pipe and its just perfect.

THANK YOU!

Isn't this supposed to be the "V6 Sepcific" part of the Mustang forum? Therefore you can kiss our asses and go **** yourself. GT's come with a true dual exhaust therefore an upgrade axleback isn't going to do **** for you asshole. Whereas on a V6 which has a y-pipe, it DOES free up approximatly 10RWHP adding duals and an aftermarket muffler. I've seen the dyno test.

P.S. Do you REALLY think it's cool to show a picture of your car being pulled over? You're a real hard ass now!

Don't let one_focused_svt get to you. He's generally a good guy. But it demonstates that many folks just don't understand the fun of building up a V6. BTW, his "pulled-over" photo was staged (which shows that some cops have a good sense of humor!)

It's been proven on multiple dyno's... The stock V6 muffler is horrible restrictive...

Please post your latest time slip... and the cost of all your mods to get that ET... Rygen ran a 12.8 for the cost of a stock GT... and with all the money you spent on modding your GT you should be running low 12's...

It's beyond simple narrow mindedness... he suffers from terminal rectal-cranial inversion...

I was thnking of a tune for the stock airbox, but went ahead and put the intake back on.

There are lots of noisy jerkmobiles around where I live, I just don't want to be associated with them. I really haven't heard any v6's with non-stock exhausts, but the way I see it if it makes a racket and gives you performance you can only see on a dyno, it's kind of ricey IMO.

But, to each their own. I've decided my car will be a cruiser, not a dragster. Rygen and scrmng and their ilk will always run circles around me, so best I can do is a smoother ride with neater gizmos.

It's beyond simple narrow mindedness... he suffers from terminal rectal-cranial inversion...

Thought I would share my story,

A week ago the ups man delivered my MAC stainless axle back muffler that was advertised to give my car a deeper , throatier sound……………wrong !!!!!! it sounded ok at idle, with a decent rumble but anything over 1200 rpm sounded like domestic rice , needless to say I put the stock muffler back on last night and chalked it up as a $180 lesson learned. I was almost ashamed to drive it, it sounded so bad.

Anyone have a suggestion of something else to try ???

one focused svt man you crack me up here is some proof for you on a dyno by switching to a GT muffler the V6 picked up 10 rwhp and 6 rwhq this was done by Justin from VMP who is a respected tuner.

Justin VMP
Then I pulled the muffler off, 11rwhp and 7rwtq on top of the CAI, no loss in mid range. Pulled the catback tube off (after the Y pipe), lost TQ. Put the GT muffler on, lost about 1rwhp and 1rwtq over no muffler.

Some of these guys couldn’t afford the GT whether it be MSPR, insurance or bought a V6 for other reasons. But what’s nice you can throw on a Powerhouse turbo, t-lok, LCA’s on these V6’s to run 11's and 12's and be able to out run about 98% of the Mustang GT’s stock, modded or even some with super chargers on the road for possibly less money not bad if you ask me.

($5-6K savings ver's a GT, some save $1,000.00 plus in insurance every year which is also nice.)

The V6 Mustangs are capable of running 11’s and 12’s with a PH turbo and the motors, auto tranny and rear ends are holding up quite well, I can’t say the same for the 4.6’s from what I read I have noticed a lot of blown 4.6’s with power adders I mean rod’s, piston (and or piston land) etc in the GT forums.

You could also just pick up a V6 throw on only a X Charger supercharger (mid 13's ) 13.70's with a stock open rear end for around $4K and would out run all stock GT's, and some with mild bolt on and still possibly pay less than the cost of a GT plus savings on insurance once again not bad.
(same with the Vortech or Procharger)

The V6 is a very capable platform.


No offense to you just responding to your comments above.

Sidenote

For the record I think someone posted Rygns PH turbo best time was 12.80 in this thread actaully its a 12.40 ET for now..

you know why your MAC's sounded ricey? Because MAC sucks lol. Even the MAC LT headers are garbage lol. If you're doing single muffler go MRT all the way. Sorry to here that man.

I got a magnaflow and it sounds pretty good especially when u get on it. Feels faster too

Yep... I had a Magnaflow to start with... but eventually I wanted a bit more sound... Scott convinced me to try out their MRT Aero-Turbine setup... My butt dyno said I picked up some horsepower... I put the car on the dyno the next day to to confirm that my butt dyno was still properly calibrated... turns out my butt dyno was fine... The MRT really was outperforming my Magnaflow!!

http://www.v6john.com/Main/Performance/Axle_back/mrtdyno2.jpg

yeah i had a 40 series flowmaster and it sounded ricey so i removed it...i think it sounds meaner with the stock one....

At start up and Idle it sounds like a V8. When i put my foot into it it starts to sound a little ricey. But what can you do? At least overall it sounds better than stock. I was at Chicane last week and one of the guys says "What have you done with the exhaust? It sounds good, like a supped up Supra. No really, it sounds good" LOL

Singe Flowmaster 40 I heard sounds terrible but my duals with the H-pipe sound awesome! Once again, if your going to go single you should probably go MRT.

HA HA HA LMAO i lovehow that asshole has not come back to back up his trash talking! hi is just pissy because,rygen scrming, MSP, and about 50 other 6ers paid less than him and can still kick his ass.......
":same mods on a v8"that is bull ****, i can put the samemodson a honda fit and outrun your gt.........Who gives a F*CK?

I'm a big fan of the GT take offs. I picked up a pair from Ebay for $60 (including shipping). I've put the right side on but never got around to putting the left one. Took about an hour (just because I spend half that time trying to find all my wrenchs). I've had quite a few people tell me how much better it sounds, I never even mentioned that I swap it out.

I still want to put the other side on, because I like the dual look, but it's going to be a little involved. So I've put it off to work on my Nova instead for now.
