M4 Exhaust GP Full System Stainless/Stainless/Black - Fits: Honda Grom 125 2017-2019

Highly recommended,, sounds amazing, now cars could really hear a bike coming,, plug and play, took me not even 10mins and that's including removing the stock one,, just becarefull removing the "Quiet Inserts" totally recommend to put masking tape around inside edges if not you will scratch it all, I didn't scratch mine but a friend have scratch his. God bless every one. Exhaust is LOUD, Sounds Exactly the way I wanted, trust me you won't regret buying it.

The sound is great I do love it. The only thing I hate is the holes that were made by m4 do not fit the Honda grom 2017 just right. I had to try and play with it for a bit and make the hole wider. It wasn't fun doing. I actually feel like I've lost power vs gaining power. I need to take to a professional mechanic to doubt check just in case. To be fair maybe I did something wrong. Maybe I needed to make the hole wider so it could fit better????

4 stars because after first wash using simple green the black paint along the header came off, otherwise deep throaty sound with precision fit and cool design!
