SZ 2.5" Test Pipes - Nissan 300zx TT

These 2 1/2" Stainless Steel test pipes replace the 2 1/4" main cats in the 300zx with the smooth non-restricted flow of 2 1/2" mandrel bent piping. These pipes will help with spool up and top end power and when mated with downpipes and an exhaust will give you enough flow for 600+ Hp!!

*** For sound reduction without the loss of power you can add resonators for an additional $120 ***
