GROM

Honda Grom exhaust options: slip-on or full system

There are two ways to go on a Grom. A slip-on replaces the muffler and link pipe and keeps the stock header, which is the simpler and less expensive route. A full system replaces the header as well. Hindle builds both for the Grom.

Fitment by year

2014-2016 Groms are covered by the slip-on, the high megaphone full system, and low megaphone full systems in stainless and black. 2017-2021 Groms are covered by Evo megaphone full systems in stainless and black. 2022-2025 Grom 125 fitments include the Evo megaphone system, a street version, black finishes, and an Evo muffler system. Everything listed on this page is built for one of those three generations.

What changes

Expect a deeper, louder note and less weight at the back of the bike. Throttle response feels crisper to most riders. We do not publish horsepower figures for the Grom range, so treat sound, weight, and feel as the reason to do it.

Next step

If you want the simplest upgrade, start with the slip-on. If you want the bigger change, look at the full systems above. For other Honda fitments see the Honda collection, or browse the full exhaust system range.

Frequently asked questions

What is the best exhaust for a Honda Grom?

It depends on what you want. The slip-on is the easiest upgrade and keeps the stock header. A full system changes more and costs more.

Slip-on or full system on a Grom?

Slip-on for sound and weight with less work. Full system if you want the header replaced too.

Does a Grom exhaust need a tune?

A slip-on generally runs fine on the stock setup. Ask us before fitting a full system if you are unsure.
