[quote name='Crusader_9x' date='Apr 17 2005, 03:05 PM']My turbo outlet is 3" as well. Although when i went up to a 4" downpipe i did see a huge difference in turbo response and overall power. All i did was get a long 3" to 4" transition from burnsstainless.

Maybe it was in your head? I think it's pointless going from 4 to 3 inch. If I'm getting 4" DP, then my entire exhaust will be 4" as well.

No it wasnt all in my head. I saw earlier turbo response by about 200-300 rpms and loss of traction in 2nd gear. Where as before the 4" exhaust i had full traction in second. Also i got horrible boost creep after 6krpms with the 4" exhaust where as when i had the 3" it would hold steady whatever i wanted.



I think you missunderstood something, i didnt go from 4" to 3", i went up to 4" from 3". I have a 4" downpipe all the way to my 4" y pipe and then after it y's off it goes down to 3".

Alright I thought you meant a transition from 4" then back to 3. Anyways I already bought this super expensive GP Sports exhaust, I'm not going to spend any more money.
