Get with Terry over at Beefcake. He or his guys will get you a really good price on some great headers.

Did you fry a cat because you were getting on it a lot into boost? Normal driving and only getting into boost once in a while shouldn’t kill a cat.

Stock cats are insanely fragile, I blew mine naturally aspirated.

I bought and Installed LTH 1-7/8 lth. And wrapped them with titanium heat wrap. I did bend outward the AC block on pass side a tad, not an issue. Great fit. Good luck

Are you running a Whipple tune?
Were you able to set all monitors for emission inspection?

Hey, ty 4 reply! 1000% they suck, i didnt even beat on car for months, my problem is not enough open road around here, so im stop and go which is irritating...... If i can extend the warranty on car, i could care less.. But if i cant, i have to step up with easier accessible cats to swap new ones on and off if they blow. the stock cats are a bitch to remove, Ya know.

Thanks Anthony

another user here had experimented with GT500 cats and found good success, but it was hardly a bolt-on mod and required lots of custom fab. Those have a stronger substrate and can hold up to more abuse.


I have Kooks 1 7/8" and like them the fitment is perfect and they don't hit the A/C lines. I have Greencats but they do still set the check engine light so you'd need a non-fouler to prevent that.

+1 ^^ I also run kooks, did not have to modify no ac line & are a good fit.

Yeah, that is engineermike w GT500 cats, very helpful guy! but just overwhelming amount of fabbing and modwork. Im waiting on some 500 cats, but dealing with flakey people suck!! So im always onto the next plan, back up plan.
Love Kooks, been hearing a lot of positive things about them.. Wow, Greencats set off CEL? WTF damnnnn! What do you think the issue is? Thanks on tip via anti--fouler plugs!!! Which brand did you get?? I dont wanna spend all that money and can't pass NY emmissions testing. NY is a commie state, cheerleader for california. Thats horrifiying!

Thanks Ant
