Seriously, I bought their race pipe and now I'm trying to find a header to replace my manifold with, but every header is manifold to main cat kits, no "direct manifold replacement" header is available :\

Damn. I wish we could like petition or something for Bonez to make a header to work with their race pipe..

Just buy whatever pipe you want and take it to an exhaust shop. They can make it fit.

yeah...they'll just connect the two and make a shorter "catback" than stock. its not a big deal unless you decide to change your exhaust later on. then you have to do more custom work.

bonez does need to make a shorty header so i can just bolt it on and take it off for inspections...here in houston i wouldnt try to get someone to cut some pipes to make my headers fit and have no cats

That would be of no use. The difference in a header, and an exhaust manifold cant be measured up just by using the stock manifold, you have to take in account the REST of the system that the HEADER replaces...the pre-cat. Thats what it replaces, not just the manifold. If you have a racepipe, you don't have cats, you WON'T pass inspection anyway(if you need cats, we dont). Just having a "shorty" header to the race pipe is doing NOTHING...only difference, its tubular, not box, but you aren't running it equal length to the race pipe because of the way its shaped..you would literally have INCHES of header running into a single pipe(racepipe). The header replaces the manifold, and pre-cat, leaving a gap for either a presilencer, or main cat, or testpipe in my case. Order a header, put it on, take it to a shop, have them CUT your race pipe, OR SELL IT, and have a test pipe made to go between the header and catback...you are in the same boat I was at one time...I had a pipe made, sold my racepipe for $50.
