Re: New highflow y-pipe makes 10hp over stock
It was done at ray's custom exhaust in smynra, tn. I cant remember what he paid for it, but I dont think he ever really inspected it really closely. It is on a 3rd gen with an LS1. The dyno was around 247 if I remember right. And its a six speed. We mostly thought the low power was from leakly rings, so its out for a rebuild. Long tubes are on the way. The car has a hella cam so I cant wait to see some big numbers. I am gonna guess 375.
