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.

i'd say 10 tops with the intake and muffler

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

How is yours set up? I've been constantly thinking of the best way to run a hose of some kind to the filter. Have any pics?

No... I dont have any pics but should have some in a few weeks. It was pretty simple but you would have to see it so you can do it the way I did.

Thanks, I'm trying to customize my airbox until the day I actually get my intake.

What kind of Magnaflow you putting in. I want to have exh. work done but I don't know what to use, plus you have to know the inlet/outlet sizes ect.

I got the Camaro/Firebird Magnaflow. 5" x 8" oval. Got it from http://www.exhaustproslinc.com/
