J's pipe went to my buddy and it made his bike a strong runner for a stock bike.
For an inexpensive pipe a PT is a great pipe, and I'm talking $175 and under on the top end. IMHO if you're going to spend any more than that I'd be giving a serious look to some of the used Aaens or the DrQ V-1's being in the 400-550 range.
Anything over $600 it's ether the DrQ V-2 or the JH
