I have found a shorty header and should have it by mid jan, my ? is can I take off the cat and gut it out for better flow or would that mess it up? I am gona buy a highflow cat but I have to save up because I want to do both cats. And what is the best CHEAPEST cat on the market?

Oh I just saw the down pipe that Matty posted on the header thread, THAT is what I want!!!!! But untill then.

OH man I want those cams on Wagners site!!

IM not sure if we need 2 or 2 1/4". I have heard the latter but when I measured my self I found the pipe to be 2" inside diameter that is unless we measure from the outside.

Just get rid of your primary cat, with a long header, and use the other cat as a high flow.

Warning with header and high flow cat you will sound very raspy.

 

Is it the high flow cat that makes it sound raspy, or is it a combo of both the header and high flow cat?

I've also heard of some people having back-fire problems with the high flow cat, why is that? Too much of a free flowing exhaust?

 

My car makes a poping sound when slowing down and I only have an exhaust.
Im sure with a highflow cat and header it would be srt4 like.

I think its a combo of the header and the highflow cat that make it sound raspy. Then again I have also heard that the pros sound like muscle cars without any cats. So I think in terms of loudness youll be getting more deep sound then rasp.
