This afternoon my friend and I installed a MRT catted H-pipe and a Eibach pro kit with BMR adj. on car panhard bar and 2 camber bolts... First off don't waste your money on buying the O2 extension... All you gotta do is un-clip the wire from the O2 harness and run them back over the tranny crossmember and zip tie them to the tranny crossmember... Car sounds a lot louder with the nice H-pipe sound... I will post the before and after video tomorrow after work...
