Xtremeflow has it all...
The Xtremeflow Hummers boast the latest is performance equiptment and for good reason. Xtremeflow is the prototype for the following performance additions on the H2 Hummer:
1st Superchargerd H2 anywhere (Used by Whipple Industeries to complete and design the production chargers).
1st Flash Program (only one with removible torque management, a milestone in power programming)
1st Aftermarket exhast and intake system desighned for the H2 (the only muffler on the market that IS NOT a retrofit off of an earlier model chevy pu or similar exhaust system) This mffler is unique for the following reasons;The Xtremeflow H2 Muffler is unlike ANY other exhaust on the market today. Unlike all other exhaust systems, this unique muffler and intake combination has been designed to provide the optimum performance throughout ALL power bands; low end, mid, and high RPM. While other companies concentrate on producing horse power at high RPM's, the Xtremeflow exhaust is designed to provide you with your highest performance from 1350 RPM's to 3675 RPM's - the place where performance is actually needed. A simple fact about exhaust ; ANY straight through design muffler will produce massive horse power gains at high RPM's (5800 to 6000 RPM's) , but a straight through design WILL NOT produce horse power at low end nor mid range where it is actually needed. When considering an exhaust system for you H2 keep in mind this is not a NASCAR and is never going to be run at 5800 + RPM's, use a muffler system that is designed SPECIFICALLY for your H2 Hummer and not one that has been tested to impress you with high RPM horse power gains .
