So I picked up my 01 Ws6 yesterday and was stoked to go cruise in her. Ended up going cruisin around with around with a couple buddies of mine. One of which has a pretty quick Mach 1. He has X-pipe, 4:10s, tune, and some cool box thing? Not sure what that is. All I have on the ws6 is a catback. Went from a 40 roll where he is best from and pulled half a car to 100. Went from a 30 where I'm decent from and pulled about a full car. I was pretty excited about this! I had been reading about the mach vs ls stories quite a bit and was positive I was going to get walked. Not bad for exhaust only. He put down 303 to the wheels by the way.
