I just received and put on my 17 inch tri-oval stainless steel pipes and really like them. As for the complaints others have talked about:
Clamps, mine work fine with no issues. I did slide them up to clamp better though.
Gaskets, mine came out easily using a small thin flat blade screwdriver. Note, the gaskets will deform, but don't worry about that, they still seal great.
Center stand hangs down 2 inches. Mine fit fine. Maybe all the feedback made them do it right.
You need to buy nuts for the exhaust hanger bolts. Not true, just bend the little tang out of the way and the old nuts drop right out.
You need to buy exhaust silicone. Mine came with a tube!
Dents in the exhaust feeder pipes. Didn't notice any, and don't care anyhow about a little ding.
Well, in a nut shell I am very happy. The sound is good but not overly loud. I may take out the inserts to see if I like that better. Sewing machine sound GONE!
Now to install that NIB Audiovox cruise control I scored on Ebay for cheap that even included a vacuum tank!
