get a turbo back exhaust system, as far as goin threw the gears, um....do it as agressive and fast as possible, unless you wanna take care of it,i would recommend to do it fast but not to grind the gears, you launching tech's sound good, do mods and make it faster, the guy with the most money in his car always wins, look at the freakish tiboron guy, twin motors arnt cheap, later
