    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!

  • Good buy for the price.

    It fit on my son's warrior great, and came with everything needed to mount it.It sounds way better than the old stock one. You have to weld ears on the pipe to mount the stock heat shield though. For the money i am happy with it.

  • Tinkering required for a 1988 warrior

    Definitely not a snap fit. I had to heat up the slip on flange & flare it to get it over the gasket & the supplied clamp is mediocre at best & had to modify that to get it to tighten up . But it sounds pretty tough. It loud but not loud & stupid . I would reccomend if you dont mind a little tinkering.
