Great option to keep your bike quiet ... and public riding areas open as a result. It took under 5 minutes to install using the allen key that came with it.

I have been using this dB Dawg for over a year. Overall I am satisfied with the performance of such a simple, but important, piece of equipment.

dB Dawg is an easy way to pass sound emissions previously unreachable from my bike.

dB Dawg, what a great and easy way to manage your noise output. Quick install, you can't beat it!

Bought this for my 2002 Yamaha YZ250F. I didn't like how loud the bike was. Even with stock exhaust, the bike was fairly loud, especially when you would give it some good throttle, it would bark very loud. This takes the bark out of it dang near completely and it seems a little quieter when normally riding. I measured the actual muffler diameter and it matched this one. So I bought it and it fits well. I have been riding the dirt bike with this on it for about a month and a half, riding about 5 times a week, and it has not moved at all or fell out. I have not had to re-jet my bike or adjust the carb at all. It does run a little richer, but it really does not take away that much performance and the bike most of the time starts on the first kick now, hot or cold. I would recommend this product to anyone looking for a quieter bike.
