I have a 2003 H2 and a 99 Corvette heavily modded with more to be modded :-)(and a 2004 M3 which is probably getting sold)

I'm actually going to sell my C6 sometime soon.....but only because I want the C7!

I've mentioned many times that OBX has been proven quite a few times. Although cheap they essentially copy the big name brands and put out virtually the same product. When I had my GTO the vette guys went nuts over OBX.

Compare the price of Kooks LT's and OBX LT's and its a no brainer. Send them to get ceramic coated inside and out and you've got a great set of headers.

As far as gains, you won't get much with shorties-long tubes is where its at. That however means reconfiguring your entire exhaust where the shorties will bolt right in place of the oem manifolds.

When I eventually swap mine out I'll go with OBX simply due to the price. Still haven't decided whether to go with shorties or LT's. Probably shorties just because I have no interest in changing the stock exhaust.

Obx seem like the way to go then. I too have no intentions of changing the stock exhaust.

I'm assuming that if the headers are compatible with an 07 they should be fine for 03-06 right?

C7 - grrrrrrr
(the vote is still out on whether on not i like the new vette)
well hey if i could i would hold on to my cars - too much blood, sweat, and cash into them

As for the headers, yeah i understand the difference between the long and the short. I have long on my vette.
Had long on my M3

Given, I would probably go long on the H2 and then do a straight back exhaust . probably straight H/X-pipe

Yeah C3s are ok, but all the ones I know of always had some issues. Whether it was body or engine or electrical.

But hey it was the 70s
