    Default Looking for more HP

    2006 Chevy Sub 8.1. It has a stock exhaust system. I'm pulling approx. 10,000 lbs.
    I wanted to open up the exhaust to get better flow and more HP.
    Any ideas on what type of system and size pipe I can go to without it affecting
    the computer.....


    Thanks Pete

    As long as you leave your converter intact you should not throw any codes with aftermarket exhaust.

    A new cat back system will certainly help, and like Retired mentioned, there are a number of good ones out there. But you may also want to look into a reprogrammer to remap your fuel and ignition to free up some more power.
