Forgot to give my review a couple years ago but this is the perfect replacement for my nearly stock NC50 which my original muffler broke off where the head bolts to the cylinder. Has a way better sound and flow than the original but not soo excessively eardrum blasting tinnitus making loud! Though don't expect serious performance gains like you would with other pipes.
I did have to slightly modify the top mounting hole to get the bolt through and theres no hole for the rear fender holder but otherwise zero issues for over a year (or 2?) time flys

Bolt on?

Happy with the look, performance and sound of this exhaust, which is not so overly loud as my prior side bleed pipe. Very pleased with the separate left side fender bracket! A real bonus! My NC50 is kitted, but still has the stock head. The mounting bracket hole on the right side does not line up properly with the hole near the stator. It is about 1/4" too low, so unable to put a bolt thru it. Tried riding a few miles on pavement with a zip tie at that spot, but the two other bolts that attach the pipe to the head worked loose. Sorry to say I am disappointed ) : # Not able to cut and weld the bracket back on, and no idea where to begin with bending the pipe either. What to do?

Mounted this bad boy today and couldn't be happier. Nice peppy sound and gained some MPH. Direct bolt on. The new fender bracket doesn't mount on the shock as described. It replaces the entire rear fender bracket mounted on the left side. You will need a nut to secure. The original bracket has nut built in. Easy as pie.

This thing is NICE looking. I had to do some trimming and enlarging of the mounting hole due to my 60cc kit. The sound is nice and I think it pulls harder on take off, but I still top out at 30ish mph. If further tuning gets me somewhere I will update this review.
Awesome sound but not too excessively loud!! 
Bolt on?
