    Amazing seller, my second time purchasing from them, always the best prices and even throws good offers your way. Description and communication always on point and expect your item to be shipped lightning fast soon after you place the order. Amazing service highly recommended.

    Well they were very responsive for my questions. After receiving the product i had a question and they responded within a couple hours yes not days which is almost unheard of these days. Shipped as they said it would very fast i was impressed alot of sales these days say it will arrive by a certain day and it doesn't. The packaging was also first class, i was also impressed on that, box wasn't damaged either. They were spot on!

    Sent them an email asking about shipping and to be sure the springs were indeed in stock. They emailed me back right away and confirmed they had them ready to ship. So I ordered them on a Wednesday night and had them by Friday afternoon! Awesome customer service!

  • 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.
