I had been waiting on getting an exhaust system until I found one that had everything I was looking for. My requirements were:
1. Low mount or underbody system
2. Full system for added power when I get a tuner and intake
3. Painted or coated black
4. Lightweight
5. Silencer option
As soon as a
link popped up about the new M4 Performance Exhaust System for the Honda Grom I knew this was the exhaust I was looking for!

The M4 exhaust system arrived promptly after my order and I got to installing it last night. The install was a breeze and it took longer to take the stock exhaust system off then it did to put the full M4 system on. The M4 system only used three mounting locations - two stock header bolts and a spacer provided by M4 bolted into a lower stock location.
Sorry for not taking better photos, but it has been running every day and my shop is packed with several other projects. I will get it out and get some good photos and sound clips as soon as it dries up.

M4 Performance Exhaust System
The other great thing about the M4 exhaust system is how much lighter it is than the stock exhaust system! I know a lot of people don't think 8 lbs of weight reduction is much, but when you only have a 125cc engine I think every pound matters.
The Grom is in there I promise
