Ok guys I have 3in pipes from the catalytic all the way back but in front of the cat i have 2in ypipe, well I messed up my y pipe i was wondering if I could put a regular 2.5in ypipe that had came off of my non boosted maxima. Let me know guys?

 

Of course you can. 3" Y will just flow a little better and free up some extra power compared to a 2.5" Y.

 

actually i think u have the whole warpspeed exhaust and its a 2.5 y pipe into a 3inch so no u cant use the 2.5inch because the 2.5 wont line up to ur 3.inch

 

where can I can another 2.5 to 3inch like I have and how much?

 

go call warpspeed
