I just installed a benz silencer on my trx 300, someone told me it will cause back pressure. The company says it only causes 2%. Has anyone ever used this item, if so any problems with your motor.

 

I tried one on my yamaha rhino and it was alot quiter but suffered on high end due to the exhaust restriction. The head pipe coming out of the motor actually turned red hot. So i am sure you will have the same results, just depends on what you want to do with it. I use mine for hunting but i like to take it out on the road too so it didnt work for me.
