Sound Test on YZ pipe on a WR

2 posts in this topic

Thinking of entering an enduro on Sunday, wondering if anybody knows what will pass 99dB's. I've got a YZ pipe on now, and still have original WR pipe and GYT-R insert. :thumbsup:

The original with the GYT-R insert will pass. Mine reads about 90dBA at 3500 RPM. The YZ muffler may or may not be below 99 depending on the RPMs they test at. Bring both of them with you.
