Re: What is your "Dream Exhaust System". (Poll)
OBX ARE in fact copies of more expensive headers. When I had my 06 GTO OBX had basically full copies of Kooks which were thousands of dollars. From what I've heard is the vette crews have had great success with OBX. If the vette guys are running them without issue they'll work on an H2. There were also a handfull of GTO guys running them also without issue.

Dynatech Long Tube Headers, straight pipe all the way back. Not really that loud IMO and even the wifey believes it fits the Hummer personality better.

Just got done doing Dynatech longtube headers, ceramic coated, Dynatech high flow cats, and through my Magnaflow muffler on there from my set up before. Sounds good, runs good, I like it. I'm not sure it sounds that drastic of a difference from the stock setup at all really, but does help with performance. Already running a CAI and chip too, so maybe that is why the changes are not as drastic, but power increases are felt.
