Hey,

Trying to figure this out: for the LS2 CTS-V, OBX sells a set of headers for about $500 with resonators. The Kooks package w/X-pipe, which is what the OBX set is based on, is about $950.

Although it's obvious that the OBX headers do not include cats, I'm guessing (please help me out here) that the basic Kooks package doesn't either.

Assuming that neither package includes cats by default, will the OEM or $485 Kooks high-flow cats work on both sets of headers? This is driving me nuts.

I'd think there is no way in hell the OEM cats will work on either. They are very thin and tall, they'd scrape the ground if you pointed them up, and they probably wouldn't fit if you laid them on their side. I think you'd need bullet cats.

What about the Kooks cats? Would they work on the OBX headers?

Your joking right? First American Racing does not make headers for the v1. Second the v has true duals. Why would anyone make a y-pipe setup for this car? You don't have a clue.

go with Kooks. last friday night i helped a friend of mine install some OBX headers with resonators and he only gained 5hp.

He has something else wrong with the car then or a HORRIBLE tune. They will both make within 5hp of each other guaranteed.

There's nothing wrong with his car and he took it to a reputable shop. It's not my car so I can't argue. I'm just telling you guys the results.

I gained 22rwhp from kook 1 7/8 with cats on a car with only a CAI. I dont see how kooks could be that much better then OBX besides fitment to justify the 17hp difference.

He still has the stock cai. Maybe that could be the problem.

There is a rubber 'snorkel' runner that goes from the RH upper side of the upper grill (VIEW LOOKING AT FRONT OF CAR) and feeds air into the inboard side of the airbox.

Remove your radiator 'beauty' cover and you will see it.
