so you will need headers that matchs up with your engine.

6.2 headers should be the same. ive seen people use 6.0 headers on a 5.7....their all similar. some exactly the same.

I have the Dynatech headers. One of the best mods I've done.

Well if heard nothing but good about dynatechs. So just order the 03-06 series and I should be good. But at the same time the price of the OBX and so far good reviews and I know there are bad reviews too but there are always haters. I could get I OBX and a cat back set up for the price of dyna's

i havent heard anything bad about OBX other than their a knock off brand. i would never spend dynatech money on my hummer. my camaro is a different story. but for the hummer, obx would be just fine. even headman headers. they have good stuff.

Another question is since OBX doesn't run cats they run resonaters is that going to hurt performance or have that evil popping sound .

5th gen. When you dad put his OBX headers on since they run resonators instead of cats did it cause a code from the o2sensers
