ur

Hey Guys, I recently installed a UR(Unorthodox Racing) lightweight under drive crank pulley on my 2011 3.8L Genesis and I wanted to give my impressions for anyone interested. Install: First of all let me start by saying the pulley does not have a dampener and the engine is internally...

I have been looking for performance parts and mods to do....seems that the only thing out there r intake filters and exhaust system.... I talked to the dealership today and they said a exhaustwill void my warranty ....really??? 5.0 with no sound ??? Gay.....ideas suggestions. ????
