Iso after market y pipe
 

Recently did my test pipes turns out OEM is too small making funny exhaust sounds like to pick up a cheap used one preferably in Vancouver

370z / G37 Axle Back Exhausts - Top Speed | engine, engine parts | Oakville / Halton Region | Kijiji

I know these guys are selling the axle back system as well as the top speed resonated and non resonated test pipes contact them

what is to small? the flange that bolts up to the headers?

The going from the y pipe to the test pipes makes a bad notice too raspie cuz it's 2.5 test and 2.25 y pipe so makes a terrible sound

hmmmmm weird.... I am running berk TP and OEM exhaust everything else and I have sweet music to my ears! I tried this setup + muffler delete pipes but that was awful :barf:

Problem is I took off resonators prior to this which makes that bad so a y pipe and custom mid pipe will do me

OIC....

If you still have the mids/resonator section you should try putting that back on first maybe
