Shipped from Japan. Approved by the Japanese govt at 86db. Well made. I like it because at 86 db its not too loud and the plus is my Grom doesn't sound like a dirt bike. Gives the Grom a good sound. A good alternative to straight thru mufflers. And it runs fine. Stock airbox, no other performance mods.

I believe that these also are a chamber type exhaust, meaning they won’t need repacked ever! Looks good in the black.

I've had that exhaust since 2013! Gave the bike a very tuned sounding low rumble. Louder than the sewing machine stocker, but not loud by a long shot. Seems a bit snappier on my butt dyno. Nothing but great things to say.

Looking good! How much was it and where did you order it from?
