custom piping exhaust vs. mfg. cat-back exhaust - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

i had a muffler shop install 2.5" piping from the cat with a so-called performance exhaust for about $250. my 240 is na with an injen CAI, i was wondering if i should go with something like 5zigen or apex n1. or will it be around the same HP gains.

any help greatly appreciated, thanx.
