Dump + Front pipe

[mupkant]

*more with the stupidity and jumping mods*

with a current stock exhuast will there be any power increase

if the stock dump + front pipe was replaced with a 3"

any1 have this done before?

There would be some little power increase but the restriction will always be at the smallest point, so you'll still have some sort of restriction at the cat-back exhaust and/or cat if you have some compliance cat. It'd be best to do the whole lot.

ok then my guess is

CAT back system is greater than

DUMP + Front pipe? (with cat back stock)

I have done exactly what you have described.

I didn't want the added noise of a cat back system, so i only upgraded the dump and front pipe. I did not expect to get a significant power increase but was hoping for better response as the stock dump is extremely restrictive.

As expected, power does not appear to have increased significantly, but I am getting better response, especially from a standing start.

In general, i'm quite happy with the upgrade. But if you are looking for a real power increase and don't mind the added noise from a free flowing system, upgrade the cat-back system first.

if your gonna do i once do it right...when i did my upgrades i started from the cat then to the turbo then when i found my cat back exhaust i finished it off i did notice power gains didnt have it on the dyno but still felt it. Also a good high flow can will help with the stock system.
