Best Honda Grom Exhaust For Power – (Unbiased Review)

If you’re still using your Grom stock exhaust system, you’re missing the authentic riding experience! You’ll never install the stock once you upgrade your Honda Grom exhaust.

Motorcycle manufacturers try to improve fuel economy and are bound to emission norms, so they underclock the engine power and performance.

Upgrading to the aftermarket exhaust is a popular modification for Honda Grom to increase the power and its top speed.

But, finding an aftermarket exhaust that gives better performance and incredible sound is as complex as learning a new riding skill.

So, to make your task easy, I have shortlisted the top five Honda Grom exhausts that boost power and engine performance, along with louder sound.

Best Honda Grom Exhaust in 2024

I have a 2022 Honda Grom and use the Akrapovic Slip-On exhaust I purchased from RevZilla. I love its deep and high resonance Akrapovic sound.

After replacing my stock exhaust system with this one, I was amazed by the engine performance and sound. I crossed 62 mph for the first time after installing it on my Grom.

So, the Akrapovic Slip-on is definitely an excellent aftermarket exhaust for the Honda Grom. If you have an older Grom model, choose a compatible exhaust.

Read on to learn about the features and benefits of these aftermarket exhaust systems.

1. Akrapovic Slip-On Exhaust

Akrapovic is a well-established brand that manufactures high-quality exhaust systems for motorcycles. It’s a Slip-On model compatible with the latest 2022-2023 Honda Grom.

As I told you earlier, I’m using this exhaust on my 2022 Honda Grom and truly love its deep resonance sound and performance.

The Akrapovic Slip-On exhaust system is made from carbon fiber, which is 36% lighter than the stock exhaust.

The CNC machined muffler inlet cap fits with the exhaust manifold, preventing the gas leakage that causes backfiring issues.

It not only enhances the beauty of your Grom but also increases its power and performance. With my stock exhaust, I used to rev 58 to 60 miles per hour, but after upgrading the Akrapovic Slip-on, I reached over 62 mph. (top speed depends on many external factors so that it may vary in your case).

According to many riders, Akrapovic Slip-on can improve the engine power from 9.0 horsepower to 9.3 horsepower. Leave this power and performance aside; I’m mesmerized by its deep, resonant sound.

Pros

• Easy to install
• Deep and high resonance sound
• Increases horsepower from 9.0 to 9.3
• 36% lighter than stock exhaust
• No backfire
• Great build-quality

Cons

• It doesn’t fit older Grom models.
• Price

2. Yoshimura RS-2 Race Exhaust

Yoshimura RS-2 is the favorite exhaust for Grom racers. If you participate in the Honda Grom racing competition, this exhaust will give you a slight edge to win the contest.

I really had to make a tough decision between the Akrapovic Slip-on and the Yoshimura RS-2. Because brands are trendy, they sound louder and boost your horsepower and top speed.

They are made from a lightweight carbon fiber material, and the price of both exhaust systems is almost similar.

I chose the Akrapovic Slip-on because of its color. However, If I had to choose another exhaust system for my Honda Grom, I would have gone with the Yoshimura RS-2 Race.

So, if you like the Yoshimura RS-2 Race exhaust design and color, go with this. It’s one of the best Honda Grom exhausts for power and performance boost.

Pros

• Increases Grom performance
• Improved horsepower and acceleration
• Diamond-shaped carbon fiber sleeve
• Produces deep and louder sound
• Durable

Cons

• Loop pipe block oil drain plug
• Price

3. FMF Factory 4.1 RCT Exhaust

If you own an older Honda Grom and are looking to install an aftermarket exhaust, FMF Factory 4.1 RCT is a perfect choice.

FMF is a USA-based exhaust manufacturer incorporating the latest Resonance Chamber Technology internally and externally to boost sound.

It creates a high resonance sound that attracts the audience’s attention on a street. Their research and development team has achieved a shorter overall length, less susceptible to crash damage.

FMF Factory is my third choice for Honda Grom aftermarket exhaust lis. However, it’s the perfect exhaust for 2014-2015 Grom to increase power and performance.

Pros

• Lightweight and easy to install
• Improves horsepower and performance
• It comes with a spark arrestor
• Fits with Honda Grom 2014-2015
• The exhaust sound is louder
• 100% made in the USA

Cons

• It only fits with older Grom

4. Hindle EVO Megaphone Exhaust

Many Grom owners in my motorcycle club use Hindle EVO exhaust. The deep, resonating sound adds a touch of excitement to every twist of the throttle.

The full stainless steel headers and mid-pipes not only provide excellent durability but also contribute to the overall performance enhancement of the Grom.

The enhanced airflow and optimized exhaust flow translate into better throttle response, increased torque, and improved power delivery.

Overall, the Hindle EVO Megaphone is a great aftermarket exhaust modification for the Honda Grom. You can visit the nearest automotive store or order online to test its sound and performance.

Pros

• Louder metallic exhaust sound
• Full stainless steel header and mid-pipes
• Heavy-duty exhaust springs
• Budget-friendly option

Cons

• Stainless steel is heavier than carbon fiber

5. LeoVince LV-10 Exhaust

If you can’t speed over $500 for Grom’s exhaust modifications, then LeoVince LV-10 is the right choice. LV-10 is an easy-to-install slip-on exhaust that fits the 2017-2020 Honda Grom.

It’s made from AISI 304 stainless steel that offers excellent durability and performance. AISI 304 is a tough material but heavier than carbon fiber.

LeoVince LV-10 costs half the price of the Akrapovic Slip-O, still offering lightweight and aerodynamic features.

So, if you want racing-style exhaust on your Grom, LeoVince LV-10 is the ultimate budget-friendly option.

Pros

• The matte finish looks good
• AISI 304 stainless steel material
• High-quality TIG welding
• Aerodynamic profile
• Stainless steel mesh
• Temperature resistant
• Extremely budget-friendly

Cons

• Round design instead of hexagonal
• Stainless steel instead of carbon fiber

Conclusion

Grom owners prefer to upgrade their exhaust systems to increase power and performance. This also makes the sound louder and enhances the overall look. Aftermarket exhausts are lightweight and easy to install.

Choose the one made from lightweight carbon fiber that offers an aerodynamic profile. A hexagonal shape is good for leaning because it won’t hit the ground.

I’m using Akrapovic Slip-On exhaust on my 2022 Grom because it boosts the overall performance and top speed, but I love the sound of the Yoshimura RS-2 Race.

These are made from lightweight carbon fiber material that reduces overall weight to increase top speed.
