Thread: Exhaust size

Based on the mods I have, is there really that much difference between a 2.25" exhaust and a 2.5" one? Based on what I've read, my guesstimate of HP for my build shows that either a 2.25" or a 2.5" would work fine. Is it that bigger is just better? Or would I actually be hurting myself by only going 2.25"?

you wont really notice a difference. youre not even close to the horsepower range where the catback becomes remotely restrictive (~300fwhp).

That's what I thought. Just like hearing someone back up my thinking so that I start to think I actually know something.
