EVO U Slip On Muffler - Yamaha Grizzly 660 (03-06)

I understand the 2 weeks to receive it, it isnt stocked. But when I received it the exhaust was not cut right and too long. Measured slip joints to make sure everything was seated and angled correctly. I was a pipe fitter for 10 years and a mechanic for 30. I ended up cutting a 1/4 inch off the front of the pipe and cutting new slots to all proper crimping. For a $420 pipe i would have expected a better product. As far as quality of materials everything seams to be solid. I would have returned it if not for my stock ones baffles came loose and i need my quad.
