exhaust performance

[GTS4dood]

Hi all,

Im putting an exhaust on my R32 in the next few weeks. so far ive been told that 3" straight through is what most people do, but a few have said to go with a 4" dump off the turbo into 3"straight through. Would 4" fit, or even be a benefit at all?????

I think most people agree 3" is plenty, some worked rb26's use 4".

But what about if the dump pipe is 4" and then 3" the rest of the way back. has anyone done this, or know of someone thats has.would it be better for flow straight off the turbo?

What kind of additional power gains can you expect from the stock exhaust over an aftermarket straight through 3"?

i have a 4inch dump on my r33gtst which goes into a 3inch high flow cat then is 3.5inch all the way back from there...flows beautifully

but i would think 3inch everything for your car would be quite sufficient

as for price on 4inch dump pipe i dont know exactly, lets just say it helps to know people...
