Motorcycle Exhaust with baffler Slip On Muffler Pipe Compatible with Honda MSX125 Grom 2013-2015 Slip-On

I cannot speak for longevity but I had read great things about this exhaust so figured I’d give it a try for the price. Quality is good and it sounds good. I’ve had a yoshi exhaust and it’s similar to that in terms of looks. I don’t think you will see any difference in performance between this and a $500 exhaust on these small bore bikes. I plan on off reading my bike so figured I won’t be upset if this one gets dented or scratched. I’m sure the yoshi and similar exhausts will last longer and are of better quality, but for the price this one is hard to beat.

I was actually surprised how nice this was for $78. The mounting bracket attached to the exhaust mid pipe did not allow for a bolt to be run through it as the stock system did. If the mounting bracket was mounted on the other side it would work. What I ended up doing was threading a bolt through the opposite side and having the bracket rest on the bolt threads. With everything tightened down, it doesn’t move. Still for the price you pay on this system, it’s great. Looks nice, sounds much better (I’ve left the baffle in). Plus this is for a Grom so any power gain you get from a “good” system is nearly null. Buy it, enjoy it and enjoy the money you saved.

Installed on otherwise completely stock bike. Once you figure out how to use the bottom mounting bracket (...more on this in a minute ***), the fitment is great. The faux carbon fiber and brushed stainless look great. The welds and spring anchors and well done. After resetting ECM, bike does run a bit better than stock. If nothing else, the weight savings is worth the money. As far as performance improvement, you have to understand that this exhaust system is WAAAY overkill. The muffler core is about the same size as you will find on 450 motocross bikes (...I know this because I have one) and with the "baffle" NOT installed, there is practically no back pressure and no scavenging taking place. It is also too loud to be ridden anywhere except on a track somewhere or in wide open spaces. I tried it with the baffle installed without the baffle end cap and this was still very loud. Then I tried it with the baffle AND the baffle end cap. This offered the best performance and was still a bit louder than stock and still sounds MUCH BETTER than stock. Defenately lowers the tone. And it runs so much better in this configuration. ***The only problem I had with this exhaust system is that the bottom mounting bracket is so poorly designed that you cannot get a bolt through it and then turn the bolt to thread it into the fixed nut of the factory mounting point. You can bend the tab on the pipe and get a bolt through it but when you get it in place, there is no way to get a wrench on the head of the bolt. I ended up having to drill out the fixed nut large enough to get a bolt through at an obtuse angle and once in place, straighten the bolt up and put a nut with thread locker on the back. If the bracket were about 1/2 to 3/4 inch longer, I could have used the fixed nut that the Honda engineers so thoughtfully provided for this purpose. If it hadn't been for that one thing, I'd have given the "Easy to Install" 5 stars. Oh well. It's still a great value and I would recommend this GROM exhaust to anyone who thinks paying $300 to $500 for a GROM exhaust does not show sound reasoning.

Fitment is off gotta modify it to fit correctly can’t get wrench on the bolt of the bottom mounting point or you can do whAt I did get the bottom parts on then just zip tie your exhaust to the bike I suggest saving up money for a better exhaust but if your on a budget grom build it’s not bad until you get money for a yoshi then you could sell this one for like 60$ on Facebook( will update if the exhaust sucks In use whenever I get this grom stunt build complete)

Really nice exhaust sounds good to, I use it without the baffle, just incase if you guys have a 2020 Grom there’s no place to mount it on there , also the bottom hole doesn’t line up but I bought the fender eliminator and I drilled a hole into the side of it and used the bolt and spacer that comes on the Grom that you have to remove to take off the old exhaust and it works perfect, the spacer is for so it doesn’t sit behind the license plate.

Installed on a 2019 SSR 125 Razkull. Yes it required a bit of massaging to get it to fit but it worked perfect. You have to bring a little off the rears and bolt right next to the rear foot peg. After a bit of modifying it worked fine. Remove the baffle and holy cow is this loud. The best part is we removed airbag on bike and replaced with clone filter, changed out front sprocket to a 13 tooth, and added octane booster and we can get speeds of 63MPH plus the backfire is simply badd ass.

Honestly i didn't expect much but damn this is a neat little exhaust. Everything mounted pretty nice. Only had to finesse her in a little bit but for the money im not upset at all. Sounds super good, I left the baffle in place. I deff prefer the upper style mounted exhaust vs the lower stock mount.

Exhaust sounds great when you remove the baffles. Pretty good exhaust for the price point. Fitment is really tight between the rear spring and swing arm. Had to spend some time adjusting the angle by the torque on the exhaust mount bolts. Some of the springs are a little loose fitting as well.
