hey I would like to know what you run?....and how much your E.T. dropped after you put headers on and also after you put slicks on...I have a 2001 WS6, its a real one, T56, 3:42 gears, I just bought it and it had 1 owner its whole life, and nothingg was done to it, still had gm muffler...it has 112,000mi and I put hooker aerochamb muffler on it,msd plug wires, and SLP lid with mac race filter..I took it to the track hoping to run 13.5 and went 13.1 on my first pass, then the tranny went out on me...I cant believe it went that quick...this is my first fuel injected play toy...I wanted an SS but couldnt find one, it took me 3 months to just find my car...I spun all through 1st but it wasnt a smoking spin, I could just hear the tires spinning but it was still going...how much you think E.T. streets would help?...im having sixspeedsinc rebuild my tranny, then dont know what clutch to put in, but installing headers also while tranny is out......I would like to know what you think will be taken off my E.T. with tranny new,street slicks, and headers.......
