Product ID: WY1009 (2009+ Yamaha R1 GP Dual Slip On Exhaust)
The trackside video was with a camera we setup and rode by while at PKA's Mac Track, and the onboard shots were at Portland International Raceway. This should be helpful for folks wanting to hear how the Competition Werkes exhaust sounds on the bike and from the side of the track.
