Like jeep said, sometimes a car is just randomly sensitive to minor mods, and like he said the computer goes into 'limp home mode' pulls the timing and adds gobs of fuel. But, I don't suggest running the car around like this very long.

You could try a performance chip or a custom tuned chip, then throw those flowmasters in the garbage.

...someone had to tell him about those Flows lol.

Shorties are a 5-6 hour job for a shop. They are rather easy to install, just a tight space to work in makes for slow progress..

Majority of shops charge 60 and hour...I'd say anywhere from 400-600.

i got my long tubes installed for just under $200 on my 5.0.  the mechanic said they slid right into place...?  personally, i like the look of the long tubes better, especially when you take a look under the car and see the giant collector .  about this whole issue of "well, you save some money getting the shorties, so you can get something else that will balance out gains of the long tubes."  i'd rather spend the money on the best performing parts so that when i get that "something else" it will be that much faster.  long tubes seem to be more of a 'looking ahead' type of exhaust.  i got them now so that when i have many more mods (when i'm 60 ) i won't have to come back and redo the exhaust.

you'll never be the fastest so you might as well go for affordability.  and as i see it screamin' ass high end really isnt necessary on a street car so shorties to me seem ideal...low cost and low end, dont get much better IMO

You have valid points, and so does Jugador.

You happened to be very lucky with your install price. Those long tubes are nice to have, but doesn't make very much sense with those Flowmasters choking that exhaust system.

what would be a good muffler?  the flows were on there when i bought the car.  so, jug, you're saying you don't use the high end power (upper rpm)?  because i know i don't race to only 35-45mph...top end is very helpful.

i don't use any power (lol), but i personally think low end is mo bettah than high end cause when do you really race to ungodly speeds?  less often than a little "up to speed" race i would imagine, making shorties the better choice in my mind.  more efficiency on low end makes better city mileage too i would think.

yeah, but top end in terms of exhaust flow is upper rpm...and me, i use the more than the lower rpm when i race...but that's just me...maybe other people only run it up to...3k rpm?  haha...not much of a race though

[QUOTE=Dilostangtr01]Dynomax is the #1 ranked performance exhaust you can buy.  Flowmasters just said like rumbling.  Dynomax provides the muscle car enthusiast with a race car sound.  Performance and sound are both a #1 for your exhaust.  Flowmaster is just been around a while and thats why everyone is used to them because they were around before eveyone else.  New era, go with Dynomax.  Magnaflows are pretty good too.              -DILO[/QUOTE]

i replaced my whole exhaust at one time...it's not like i had an h-pipe then had to buy a short h-pipe...so it really wasn't that much more expensive ($370 for everything).  about the mufflers...how does the dynomax sound compared to the flowmasters?  what about the spintech mufflers?
