Ebay Y pipe reviewed and dyno'd

370Z Purist

Seeing as they're completely different sections, probably not. If anything, this might result in some rasp, purely due to the resonance of a larger diameter of piping. I haven't seen anyone yet combine the short tails and any other mod other than TPs, which can be very raspy at normal cruising power.

I am also looking into doing test pipes along with the expanded y-pipe, but I'm extremely worried about the sound. The short tails can get annoying if I'm floating around 3k for whatever reason. It should produce pretty good gains though, since replacing the cats and changing the Y pipe pretty much converts the entire thing to straight piping. Headers would be the next step, although at that point, the sound would probably just end up being terrible in every way: loud, raspy, and with lots of drone. Sell everything off and get a CBE at that point, just for your own sanity.
