I met Murray about 10yrs ago from Mountain Mod, he is great guy. The business is kinda a 1 man show, builds great seats/hoods. Have both products on my TRX1. Dont much about the exhaust system, but noticed it says E&S on the muffler. There a yami dealer out of Ft Sask. There good people too. Other than the turbo, best part of my sled is the MM seat!
