Leo Vince GP Corsa Exhaust System for Honda Grom

When i have decided to upgrade my Honda Grom, swapping the exhaust is usually the first step. A new exhaust pipe changes the soundtrack, boosts power, and simply gives a new look to your bike. During my research, one name kept showing up: Leo Vince. Their GP Corsa exhaust seemed like the spot-on upgrade for my little bike.
What Is the Leo Vince GP Corsa Exhaust System?
The GP Corsa was mainly built for 250cc to 500cc machines, Grom riders love it because it improves the sweet spot between looks, punch, and price. The made with AISI 304 stainless steel, and the inside is packed with heat-proof fiberglass to make it long-lasting and reliable.

- Precise CAD/CAM design for a perfect fit
- MotoGP & Moto2 inspired styling
- Big weight savings over the stock exhaust
- Better power and throttle response across the RPM range
- TIG-welded 304 stainless steel pipes
- Works with your bike’s stock fuel settings
First Impressions
When I finally opend the box and lifted the GP Corsa EVO slip-on, I felt that I was holding something special. Leo Vinces long-standing rep for top-shelf exhausts shined through, and this piece certainly lived up. It promised a sharper stance, feather-light weight, the right growl, and an honest bump over the factory pipe, and so far i am convinced.
Look and Build Quality
Right away, I was struck by how good it looked. Its brushed stainless-steel link pipe had that neat, almost mirror finish, and the carbon-fiber muffler sleeve added a hint of sportiness. The technopolymer end cap sat flush and clean, rounding off the design nicely. Most important, the assembly felt rock-solid and every joint was smooth, every edge was finished, and nothing rattled when I shook it. Nothing about the piece shouted for attention, yet the overall vibe was sharp and honest.
Performance and Weight Reduction
Slipping it on reminded me how heavy the stock can really was. Thanks to the CAD work, all I needed was a couple of basic tools, and the header lined up just right. Slip-ons usually dont move the needle much on power, yet the bike felt quicker off the throttle; the airflow seemed freer, and the ride just flowed better. That little jump in response made an already fun afternoon even more enjoyable.
The Sound That Changes Everything
Now lets dive into the best part: the sound. Before the swap, my Grom sounded dull and flat, like a quiet commuter scooter. After I bolted on the GP Corsa EVO, the little bike came alive. The exhaust note got deeper, tighter, and way sportier, yet it stays mild enough not to annoy neighbors. Its the perfect mix of aggressive and street-friendly. Every twist of the throttle puts a grin on my face-it honestly makes my Grom feel like a MotoGP machine zooming around town.
