ok i'm looking to replace my stock y-pipe...im not doing headers at the present time so im looking for a easy/cheap alternative to help out flow a little bit...here's where i need help...im lookin at 3 y-pipes to bolt up to my stock manifolds right now..

-SLP...stainless steel, direct bolt on...only problems is its only 2.5"
-Borla...direct bolt on ect...2.75"
RK Sport...2.5" into a 3" collector...the only thing i don't know is if this will bolt directly to the stock manifolds and fit w/out and fabrication

if anybody has any experience with any of these please let me know what u reccomend...thanks

 

twin 3 inch pipes is WAY OVERKILL on a stock manifold car. Most people around here are running 3 inch cat-backs, and that is just a single pipe. Really no need to go over 2.5 inch Y until you start making serious HP.

 

i think you are misinterpreting the ypipe measurments. as far as i know, the slp units have 2.5" pipes coming off the manifolds, then they have a 3" collector. and i'm sure most other companies are the same way.

 

no im just looking for somethin w/a 3" collector, not 2 3" tubes (i said 3 y-pipes, as in 3 different brands)...so who's had good/bad experiences w/any of the above y-pipes?
