I talked to a Hummer mechanic about performance mods made to the H2. He said he drove a H2 with Headers, aftermarket exhaust, and the computer upgrade and felt a big improvement. I am thinking of adding these modifications to my H2.

Has anyone else make just the above mentioned modifications?

Any comments?
