Impressed
Absolutely transformed my street from a humble kitten to a roaring lion. The sound is fantastic, but not over powering to an annoying level. Pretty easy to put on after working like a dog to get the clamp off the original muffler; ended up having to use a breaker bar, which made it quite simple. 30 min install.
Most importantly, people finally look up when I'm riding by. I definitely feel safer knowing I'm heard.

In all, this went above and beyond my expectations.

This was a gift for my son's Street 750. Lives the bike up over the too quiet stock muffler. Fit well and easy to install.
