I've got a 300EX and am wondering which exhausts will meet the 93dB requirements at Silver Lake MI? Are they enforcing this rule? I haven't been there in about 3 years.

Are they enforcing it? If so, what pipes fit the bill with the best performance?

If you aren't throttle happy in the parking lot then more than likely you won't be tested just make sure that your USFS approved spark arrestor is installed properly and you should be fine. I had a race LRD on my 400ex, Dubach on the YFZ, and FMF on the 250R and haven't been tested yet.

I finally got the exhaust that came with the quad and it's a White Brothers E Series and head pipe. That should work fine for what I need.

I was there yesterday and they just checked for a Spark Arrestor and they let me right in!
