Review on Ultimate Motorcycle Slip-On: Honda Grom MSX125 (2013-2022) Compatible by Jeff Kersey

The whistle looks great. Good material and color. The springs are very tight, it's a shame if you're weak and tight lol. Carbon fiber looks cheap but looks the way you want it to. The sound is actually pretty damn good. It comes with a baffle that has a baffle so you can technically control 3 levels of audio with that one whistle. I was very pleasantly surprised at how deep the Thunder sounds when there are no baffles in it. I like it, it's deep and grainy but not enough to upset the neighbors or anything. I've heard of people breaking welds on the manifold, so I made sure to look at the inside weld of the pipe. It looks good and shows signs of heat odor. Don't flip it like it's the end of the world folks and be sure to replace that exhaust gasket you plan on reusing, it's only a few bucks.
