Performance question

[Screeper]

I would caution against the exhaust uless you like a large increase in exhaust noise with negligible performance results. I installed the exhaust on mine and it does make the hummer sound like a hummer. However the highway drone, and the ability to actually hear how hard the engine struggles gives me some regret. I agree with Klaus. The only thing which will make the H2 a fast truck is the supercharger. I wish I had one. To give you some idea what you are up against, just picture a corvette pulling a four thousand pound trailer.
