I'm planning to switch from boomtubes to the Pypes mid mufflers. The boomtubes don't go very well with my o/r prochamber. To those who have mid mufflers, how easy was the install and how long did it take you? What kind of fitment issues were there if any. Where's the cheapest place to get the mid mufflers? Thanks!

just curious but what was wrong with the boomtubes? The mid muffler is similar to boomtubes i would think, you do get the mid mufflers but otherwise the actually actual back is just like loudmouths?

I think he was hearing trumpeting in upper RPM ranges.

Like Riptide said,the boomtubestrumpet at WOT with the o/r prochamber. The sound is like "Braaaaaaap". I guess because the exhaust is so free flowing now that the boomtubes "spider webs" (louvered core) - that were designed to clean up the sound and differentiate them from the loudmouths -are useless at WOTand they soundpretty much likeloudmouths. [:'(]Because the mid mufflers have the mufflers in the middle and not at the rear,they don't have that trumpeting problem like muffler deletes do.

correct, cant wait to hear them!

have you thought of just adding resonators? it would be cheaper. i just know a guy who heard my setup with resonators/off road h and liked it better than his setup with midmufflers/off road h.check my sig if you haven't hear my clip

i would recommend the boomtubes because they sound better than mids ,IMO

Mid-Muffler with a o/r pipe of any kinda sound Bada**. Post a sound clip when your done!

How muchdid it cost to get the resonators and have it welded in? Do the resonators mount after the H-pipe? What's the length of the resonators that you installed and who makes them?

By the way, since you have an off road pipe, did you notice trumpeting with the boomtubes at WOT too?

Pypes Mid Muffler with an O/R H was the best sounding S197 I've honestly ever heard.- I should know, I had it. It is however, very loud- which is why I dont have it anymore. I am searching for a lower sound than that, and plan on doingLT's with a high flow catted H.

A Prochamber should mellow it a bit when compared to the O/R H I hadhopefully, and sound awesome. If you dont mind the car being loud (but unbelievably mean, not raspy) I say go for it.

I wouldnt change the mid muffs for ANYTHING that I've heard on an S197, andIve heardjust about everything.

Post videos if you do it.

I recommend installing on a lift if you have access, or have a shop install it for you, as it is a PIA to install- but well worth it man :)

the resonators were $85 installed at a local shop. i'm not sure who made them, i think it's dynomax, but they're about 12" long, and the inside looks EXACTLY like the inside of the boomtubes which i thought was cool. it's almost like having a midmuffler setup because they install just after the crossover point (either H or prochamber section) and just before the overaxle section. i did have some trumpeting at WOT before i installed the resonators butnow it's pretty much gone.

what are you going to do with your boomtubes after you take them off? I'd be more than willing to take them off your hands for you!

just did my mid mufflers a few weeks ago.... running an SLP modular x with high flow cats.. install wasnt tooo bad.. a lift would have made 10254 times quicker/easier.. its just getting it all to line up and not rattle on the axle or anything is the only challenge.. but my tips lined up like a charm.. didnt even have to adjust them..

my only thing is that the mid mufflers with the cats (even tho they are high flow) are not loud enough inside the car.. which i dont really understand.. but im taking it in to a guy that fabricated the dumps for my cutouts, and have him try and adjust the rattle on the axle (which only happens at 1050 RPMs by the way).. and im going to have him take the cats out and slip int he straight pipes.. should really make it sound alot louder/better.. i will post more vids with them off..

but the sound the produce is awesome i love it.. deffinately my favorite system for the stangs.. these with a good mid pipe and some hooker long tubes are unreal..

if you go on youtube.com and look at my videos.. you can see a few that i made real quick after i installed them.. my member name is bigdirtyblack ... just type that in the search and they should come up..

and heres some pics and info to get an idea of the tips and clearance with the pipes..

I found this video of someone running the prochamber with mid mufflers. I don't know if his is o/r or catted. Most likely o/r considering how loud it is. Anyway, it sounds damn good! I like the sound of the supercharger too.

harraid5711,

At this time I don't think I'm going toweld resonators intomy current setupsince I don't want anything permanent. Now if I can find resonators that I can just use clamps with then I'll probably do that instead. Anyone know of any resonators that uses clamps?

If I decide to get the mid mufflers thenI'll sellthe boomtubes. I'll let you know.

too bad you'll be leaving the BT Crew[:o]

I found these. They can be used as resonators. I can cut the exhaust pipe just after the prochamber andprobably useband clamps (http://www.jcwhitney.com/autoparts/ItemBrowse/c-10101/s-10101/p-100000234965/mediaCode-ZX/appId-100000234965/Pr-p_CATENTRY_ID:100000234965) onboth ends to install them.

I think I'm going to try these resonators instead. Overall length is 12". I plan to cut the straight section of the over axle pipe and mount the resonators between that and the prochamber. I'll use the stock OEM band/sleeve clamps to secure the prochamber to theresonators and buy two more clamps to secure the resonators to over axle pipes. Anyone know ifit's important to stagger the resonators by mounting one further down the exhaust pipe than the other? I heard some people do and some people don't. I guess with the resonators in the middle I would have a mid muffler system. :D

thanks, ive been trying to get my hands on a set for probably a month or so now and noone has them in stock...

i had the guy stagger them about 2". not sure if it helped, but it sure couldn't hurt ;)


and you're right, with this combo, we have a boomtube/midmuffler setup!!!!

Boomtube/mid muffler crew! :D

Hmmm...I might not stagger mine. It'll be easier to just slip the resonators onto the rear of the prochamber with the OEM clamps and then cut a section of the over axle pipes and clamp the rear of the resonators to them. We'll see how it turns out. Gonna order the parts required and hopefullyinstall them next weekend. I really hope this turns out good. The search for the perfect exhaust sound is the bane of most S197 owners. [>:]

yes it is...i'll be checking back to see how it sounds. good luck!!!

Mid-Muffler FTW. You will love them

Staggered resonators help reduce and eliminate the drone!

Your car is one of the best sounding cars I've heard and hopefully with the resonators mine will sound similar even though I have a prochamber and you have an H-pipe. I ordered two Dynomax bullet mufflers (http://store.summitracing.com/partdetail.asp?autofilter=1&part=WLK%2D24215&N=700+115&autoview=sku) last night from Summit Racing to use as resonators. They're 4" round with a 12" case length. Should get them mid week or so.

I got the Dynomax race bullets last night. They were under 40 bucks each. They're not the prettiest but then this isn't a beauty contest.[8D]They're definitelya straight through muffler/resonator though. Here's a couple of pics.

The only problem I foresee is that the straight section of the over axle pipes aren't exactly straight. They have slight bends in them here and there before going over the axle and to the rear. If I replacethose "straight"sections with therace bulletsthen it's going to throw my boomtubes out of alignment again. [:'(]

I know therace bulletsare going to reduce the sound volume a bit and I'm hopingI'll still like thenoise. I like it somewhat loud at idle.This is going to be like having fourmufflers (two race bullets& the boomtubes) :eek:Shoot...I might end up selling the boomtubes after all if the volume is not to my liking. I think it'll be louder at idle if I got rid of the boomtubes and have just the race bullets. Hmmmm...
