Machine tune GP-MAGNUM Cyclone EXPORT SPEC Certification gouvern

Quality and TextureThe GP-Magnum full exhaust system from Yoshimura is constructed from high-quality stainless steel with a polished finish for the piping. The silencer features a carbon fiber cover paired with polished stainless steel end caps. The overall fit and finish are flawless, reflecting Yoshimura’s reputation for premium craftsmanship.Feeling of UseThis full system offers significant weight savings compared to the stock exhaust. It also provides a deeper, more aggressive sound and greatly enhances the visual appeal of the bike. It’s a noticeable upgrade in both performance and aesthetics.Recommended Additional ProductsAn aftermarket exhaust is usually my first modification on a Honda Grom. Following that, I recommend upgrading the suspension to address the stock setup, which tends to be under-sprung.Installation DifficultyInstallation was straightforward and took about an hour. Basic hand tools and a bit of mechanical aptitude are all that’s needed to fit the system to the engine, frame, and rearset. The instructions were clear, and everything aligned as expected.Cost Performance and ComparisonYoshimura products are typically priced higher than competitors, but in this case, the GP-Magnum full system is competitively priced and offers great value. It’s on par with other high-quality offerings in the market.Shipping and PackagingTo save on shipping costs, I opted for sea freight over EMS. The money saved was put toward other parts. Despite the longer delivery time, the exhaust arrived extremely well-packaged—protected in bubble wrap and air pillows within a sturdy cardboard box.Concerns, Cautions, and Purchasing AdviceI highly recommend purchasing from Webike Japan. It’s my go-to source for everything motorcycle-related—from service items to performance upgrades and riding gear. They consistently offer great availability and competitive pricing.

This exhaust system is high quality made. The welds are so consistent. Great craftsmanship on this exhaust.Installation is very easy.The sound of the exhaust is deep which i really like but maybe thats because i did cut the baffle on the header pipe.

I could not install the YOSHIMURA Exhaust System for Grom that I used before, so I bought this product and installed it this time.
Installation can be done without much difficulty.

The replacement felt the same as last time, but the acoustics were better and the Axel sounded better when it was opened.
And Torque at medium and high speeds has improved.
Fuel consumption is also improved. The fuel consumption is increased by more than 70km/km every time we go on a tour.
The highest I've ever done was 78km/? The highest I have ever reached is 78 km/km, and my touring companions are also very surprised.
We are very satisfied with the Stainless Steel Specification with good cost performance.

First of all, it looks beautiful.
Tension↑

I put it on and drove about 50km.
I think Torque is above NORMAL even at medium to low speeds.
It goes up to high RPM without any problem.
And very bass heavy, but not unpleasant sounding.
Maybe it's the sound that makes you feel like you have more power, but it's fun to ride! I think it's fun to ride!

At this price, with this texture, this fun!
It is Recommendation

Say goodbye to HondaOEM's Ultra Quiet Exhaust System.
YOSHIMURAGPMagnum was introduced.
I was troubled for about 30 seconds with MORIWAKIZERO BP-X which will be released soon.
I decided to go with YOSHIMURA.
MORIWAKI's Exhaust System is an integrated structure, so it can be used on Grom with strong vibration.
I thought the weld between the Exhaust pipe and Silencer might not allow the vibration to escape and break.
I decided to use this Exhaust System with split structure.
As for the Design, it is a pleasure to own with a very beautiful finish.
It is a gem that will satisfy you.
The exhaust pipe also has a subtle curve, and when changing the engine oil
It doesn't seem to interfere. ← this Large thing!
As for the sound, Idling sounds like a pompom boat and is very cute.
But once you open the Axel.
Sounds pretty good. (A little Large fineness) and Adrenaline is secreted.
I thought it would be so much fun just by changing the Exhaust System.
I am very satisfied.
SSCover is also the best cosmetic.
