Heavy duty and ready to mount
There were very few after market mufflers to fit my 98 Yamaha 600 Grizzly. This one is not only shielded but very well built. All I should have to do is wrap heat shielding around pipe to header and I'm through. I highly recommend this product

Perfect fit
Muffler fit perfect and looks better than I expected not being an OEM muffler. I am glad that I found this product and would recommend it to anyone else looking for a replacement exhaust system.
