Any benefits in going from 2.5 inch exhaust to 3 inch
Have a 2005 Mustang Gt and I'm trying to get all the horsepower that I can and I was wondering if there would be any real benefit in pipe size...
Thanks in advance.. |
Unless you have a built motor, ported heads, cams, blower or turbo, etc. you're more likely to hurt performance putting 3" exhaust on your car.

wont have enough back presure, dont do it
|
Plus, it'll sound like crap unless you do need it. The loss of back pressure will give it a raspy sound over a hearty sound. Now 3" tips yes, but piping should not be over 2.5" unless you have SC/Turbo or a built N/A motor.

You don't make enough power to need 3" exhaust.

For something as small as a 281, even 2.25" is adequate. Unless you get more cubes and a blower, stick w/ 2.5" at most. |
Thanks for the info... That ends that idea..

Plus, clearance might become an issue....Half an inch might cause some scraping on speed-bumps and the like.

It's not a half an inch on the tips, it's on the actual piping.
|
Like people have said above there is no reason for 3" unless you have huge power adders and even then the difference in power is minimal. Not to mention ive seen alot of just block or power adders add hp this way but loose alot of torque doing it.

I think I have 3inch tail pipe ends and my car sounds nice, looks nice and everything. I didn't put it on though, that's how it came with the car.
