Entering a XC event this weekend with my '06 yz450f but I've never had to pass tech with it before. Normally do GP's on a closed course.

There's a 99decibal limit, i'm wondering if anyone has ever failed to pass tech because the pipes too loud or if anyones knows what its putting out.

I've had a PMB sparky screen and just added their quiet insert but honestly, don't know if its any quieter.

I may be bringing the wifes WR250 as backup!

I passed a 98db sound check with a pro moto billet endcap along with their quiet insert on my 426 with a freshly packed pipe. Just packing the pipe lowered sound levels by 3-4 dbs. Good luck. -Cam
