Does anyone have any #* on how much hp I'd gain after I put my Magnaflow in? How much would it be with just the muffler? And what difference would it be if I got a Hi-flow cat later on?
Would this also depend on the intake as well? I don't have it yet but I'd expect at least a gain of around 7-10 hp from that. Anyone know? I'd like to be able to estimate how much power I've gained since I started modding. Thanks.
If you were to put a the new intake the high flow cat and a proformance muffler on I would say about a 10-15hp gain. You should run a ram intake with hose like mine, I got a few HP out of that. Also it sounds kewl at idle... it whistles
