Q: What would you say would be the decibel rating. My bike is excessively loud and tracks don't like me on their tracks becuase of it. I was looking at the GYTR 4.1 because it says it meets the 95 decibel requirement. But it would be cheaper with the FMF 4.1

A: I am still unclear as to what exhaust you are currently running on your bike. If you are running the 4.1 muffler this part should put you in around 96db.

Q: Measurements?
Over 3 years ago
HI, Can you tell me the diameter measurements of the pipe insert and also of the flange? I have a Grizzly 700 muffler that doesn't look like any aftermarket I've been able to find and it says to use YMS-02 screen type arrestor.
