well folks I just got my zx636's pipe in. I really like the way it looks but good god the design is shit... I posted this on the 10 side because i know there making one for the 06. The end pipes are really neat and well thats about all the good i have..... The welds look like seagull shit, the design has enough shit in the way of the exit to get fined by the fire marshal. oh the down tube is really long so its almost like a full sytem with out the headers. however the joints where they conect leak like a 3yr old.... On my zx10 i got the micron and could rant and rave on the great craftsmanship but i'll save that for another thread. but back to the laser, I have a expansion chamber...? WTF does a 636 need a expansion chamber for. I had to make about 4 trips to the hardware store for shit that was "saposed" to be there. the pipe weighs 10.8lbs. I just wanted to let you guys know that if you want a 600 dallor kick in the nuts this is the way to go!!!!!
