all of the above man. use the technigas exhaust instead. the vince pipe has several restrictors welded inside that make it sound good but stop complete scavanging. i used all malossi parts in my zx/50 '01 and now have almost 16,000 miles on it w/ top end 65-68 mph.

The odometer reading is actually in kilometers, not miles.  I made the mistake of thinking I had 13,000 miles on mine but then noticed that it was in kilometers, then 6,500 didn't seem so bad.  With two modifications (boss drive/exhaust washer removed), this bike can reach 50mph.
