Billy Boat Exhaust
Just put a Billy Boat Exhaust on the Hummer.
I got to say I love it, it sounds awsome!
It has also made a significant difference in power. I know alot of folks say go dyno it before and after, blah blah blah.
There was an instant notice in power from throttle response to gas milage and no more humting gears on the autobahn while going up hill.
