Dont expect anything huge. Maybe like 5hp gain and a few extra if the intake is upgraded. When I got my flowmaster put on, the car def. had more kick to it but nothing outrageous.CZ28.com SN-SFireGT98<br />-1998 Mystic Teal Metallic Camaro, V6, T-tops. <br />Mods-Whisper Induction Lid; K&N Air Filter; Flowmaster Am.

Chevy High Performance Magazine (I think that was the one) dynoed a stock 3.8 and then installed flowmaster cat-back and re-dynoed and showed 10HP/12TQ gain. theres a thread about that article around here somewhere.\'01 Mineral Grey SVT Cobra<br />-former F-body owner
