hahaha ya, it was only about 2 minutes before I walked in the front door and went into the garage. About 15 minutes later I had her fired and was looking for a pair of ear plugs because it is freaking LOUD. You weren't joking there dez... It makes my CHM system on my CRF sound like a stock TRX. But it like louder, and the places I ride at there is no homes or noise restriction so the loud the better .
It is very loud, but the louder it is the more it is breathing and the more it is breathing the more performance you are gaining (in most cases). This pipe just rips man. I am 100% convinced (from my pipe testing on my CRF450) that the longer, fatter head pipe is what gives the CHM that great torque down low... which is what I wanted. I did not have access to a dyno during my testing so I was doing the test's from the "seam of my pants".
