Someone recently used my old website (yep, still active I guess after shutting it off 2 years ago) to buy an exhaust kit. I did return the fund since I don't make them anymore. So please, don't go on the website to buy exhausts... but all the links for the different maps are still working.
This might be a stupid question, but is a new exhaust and the airbox mod absolutely required for the Viper RevB map? Also if I am using the speedoDRD will it interfere with the power commander? Also which power commander is compatible with the tune, can I use III, or do I need power commander V?
