I am a master certified tech. I purchased the exhaust for my h2 hummer and i am not pleased with this system. My stock exhaust peeformed better with my dynatech headders. The gibson muffler is a two in one out design and does not flow properly. The fitment is poor. It you look at the onstructions on the gibson web site you can see the front hangar on the exhaust will not line up properly to support the weight of the system causing pressure on the engine pipe. Very disapointed with the system.
