3inch exhaust cause damage?

91cobra5.0 · May 27th, 2008, 12:43 AM

i know a 3inch exhaust is over kill but can it damage anything?

e3sean · May 27th, 2008, 12:57 AM

on a fairly stock mustang the only thing it will kill is your power.. you need some backpressure.

91cobra5.0 · May 27th, 2008, 01:08 AM

how much backpressure? say mufflers and a h pipe?

e3sean · May 27th, 2008, 01:13 AM

O/R H PIPE and a set of stright through mufflers is fine 2.5"

e3sean · May 27th, 2008, 01:14 AM

u need packpressure for low end torque then good flow for high end power.

ok heres a question, why do lots of people go with shorties? why not long tubes

if you get long tubes you gota get the h pipe for them and i think some states like cali dont allow them

83fox · May 27th, 2008, 01:32 AM

i think its a lot harder to change the starter as well, if that ever happens to go bad

91cobra5.0 · May 27th, 2008, 01:34 AM

ok but why do people run shorty's i though long tubes were the most benifical?

sniperrider · May 27th, 2008, 01:48 AM

because of sound preference and clearence can be a problem, they get close to the ground and cause little difficulties in the engine compartment, such as the starter like 83 fox said

No it won't damage anything besides your wallet.

baine21225 · May 27th, 2008, 11:24 AM

long tubes would make minimal more power on your application and they make it harder to work on other things, but i'd still prefer them

ryans88gt · May 27th, 2008, 12:42 PM

I'm not a fan of long tubes unless the car is going to spend the majority of its time on the track. Shorties keep the engine bay, starter, floor boards cooler, make it easier to work on, cost less, and do not give up much power. Personally, I think they sound better. Shorties on the street.

3 inch exhaust will not hurt anything, but you may loose a little torque from decreased scavenging, but probably not if you are replacing cats with no cats.

i considered eventually doing shorites but ppl say spending 300 bucks on it is a waste of money...

i think the main reason i wouldnt want LTs tho (besides the money) is id have to buy a different midpipe and i think it would be too loud lol

You can buy stainless shorties on Ebay for $120.

DeMello · May 27th, 2008, 12:58 PM

like 3 hp and not much difference in sound right

ryans88gt · May 27th, 2008, 01:04 PM

with stock heads and intake, probably no much of a difference since the heads and intake are the major restrictions. However, once you have heads, cam, intake, exhaust mods are important for making power.
