Hummer H2 For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.

Hey Thanks, Can you tell be the part number. Is it done? Let me know how she runs and sounds. Could you tell me if it will fit a 2006 H2 stock, except exhaust - Borla, and lift. I mean do I need to buy anything else for it to work. Cats? I had longs put on my TA. I think all I had to get was the y pipe. So I'll probably need that?

I think my shop ordered from Summit, but Dynatech headers for GM 1500 2007-2014. Given you have a 2006, you might need that year fit, but mine was the 6.2. But they work. We had to piece together the rest of my exhaust but I went true dual with my 1000hp setup. Otherwise they would bolt up. No cats. The y pipe is made by Gibson for it, but they took so long, we just made our own crossover pipe. You might have to do a little custom fab but not much on the cat back you have.

headers are in and fitted to the muffler, just building the dual exit now. Should be done by March 24. Will post up pics. It should be started and tuned this week.
