Read so many good things about Mr. Ritter and his exhaust kit for the Polaris trailblazer 250. I sent him a friend request late one nite and he called me and we talked about the kit. This man knows his stuff and it was like I was talking to a friend. I ordered the kit a few days later. Shipping was super fast the directions were easy to understand. What a change it made to the quad!!! Woke this thing up a bunch! Thank you Mr. Ritter for taking you time to talk to me answer all of my questions and for an amazing kit for my quad.
