My buddy Jake bought a race raptor but the machine had an exhaust that was too loud for trail riding in WI (96db). So we did a sound check on the old exhaust, swapped the exhaust out for FMF Q4 pipe and power bomb header, then we retested it to make sure it would pass a sound check.

Here is the video of the sound check stuff we did for battlestuff

 

With the first pipe on there you would need to wear earplugs to avoid going deaf. That's not just loud it's what I call stupid loud. I'm glad to see it quieted down and legal. We don't need anymore trails and tracks shut down.

 

So what was pipe #1?
