the header piping also seems like its smalller than my cat, could that be causeing a leak since it doesnt fit into the cat right so exhaust gas just leakes out?

l figured SHO does it best, so post on here instead of taking it up to mineke and PAYING for their opinion. thanks guys

What kind of header is that?

Normally there's a weird donut type gasket but that looks like it's a normal flat gasket.

Buy a megan racing high flow cat.

You'll see some gains and it will make it bolt up all nicely. Buy the 2.25'' or whatever your header collector is. If u have a catback make sure it's the same diameter or larger.

personally i have 2.25'' header collector, 2.25'' hi flow cat, 2.36'' catback

The header is ment for a complete exh. sys. The stock sys uses a doughnut style gasket between the front pipe and the cat, held together by a tension nut, bolt and spring set-up. The header you have utilizes a flat gasket. Some co.'s offer a joint to fit in between the two. I couldn't name one (darn memory). If you want the full "effect", go with their high flow cat too, or try to find one of thoes joints. You could always go with a different header...
Good Luck :byye
