This full system exhaust sure can change your grom! Not super loud, but good enough to let other driver notice you. Easily notice the acceleration power difference, and the out look just stunning. Beautiful craftsmanship from Yoshimura as always!
About quality and texture: I am happy with the quality of R-77S full exhaust system from Yoshimura. Made up of a two piece stainless steel exhaust pipe that connects to the stainless steel sleeved and carbon fiber end capped muffler.About the feeling of use: A very impressive looking exhaust for the Grom with a good sized exhaust pipe that produces an increase in power and torque with a delight full exhaust sound.Products to buy together: A high flow replacement air filter would also be desirable to purchase along side the R-77S full exhaust and Yoshimura have one available via K&N.Difficulty of installation: The process to install takes about one and a half hours to complete. A new gasket for the forward mounting flange is recommended. Not difficult to do.Cost performance and comparison with other products: Good costing as you are receiving a high quality manufactured product using quality materials that is proven to increase performance as compared to a slip-on exhaust that retains the Honda exhaust pipe.About shipping and packaging: Sea frieght was my perferred method of shipping due to the lower cost but currently unavailable due to Japan Post. Webike kept me updated on the status of my order up to when it shipped. The parcel arrived within the expected date range and was well packaged with no chance of the part being damaged.Any concerns, cautions, or advice when purchasing: This high mount exhaust system is designed for the 1st generation Grom as it comes from Yoshimura but can be made to fit the 2nd generation Grom with some fabrication.View Detail
Since the weight of the upper part of the car body has been reduced, the car body feels so much lighter. Seems like Torque's trough around mid speed is gone! Peak power is up a little. This was not only a feeling, but also an increase of about 4 Km/h in maximum speed on level ground.View Detail
I met a friend after the installation and got high praise for the exhaust sound Are you sure it's government approved? It's such a nice sound It's not enough of a sound to disturb the neighbors, but it's a nice sound that you wouldn't expect from a 125cc car I do? My friend complimented me on thatView Detail
I might hesitate to buy at the price, but I bought it was Large Correct! It was nice to be towards the Full Exhaust System ◎
The sound is really cool! It has become fun to run.
I got installed at Motorcycle store. Since Tail lamp was originally attached directly, there was no problem, but maybe it might interfere somewhere ...
Many webikePoints were reduced, so I could also buy other parts ( ??? )
I would definitely recommend it to those who are on Grom!View Detail
If you are doubtful about Slip-on Silencer, let's choose the Full Exhaust System. Because it is YOSHIMURAExhaust System of the corner For Normal engine Injection setting etc etc. There is no necessity at all.
My EngineSpec. Mukawa SStage, Mukawa river BigThrottle (Power Filter) However, the setting in FI con is (F). Correction is +2 (7) It's patchy..
You can remove Baffle at Hexagonal Wrench. My EngineSpec. In the case of Power, Power comes out, In the case of public road use, there is noise and low speed Torque reduction, so if you likeView Detail
Fácil de instalar, diseño muy bonito y de contrastada calidad, sonido agradable. Os lo recomiendo al 100%.El haber elegido a la empresa DHL para el envío del tubo de escape fue todo un acierto ya que de forma muy rápida te gestionan los trámites que están sujetos a revisión aduanera.View Detail
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.View Detail
Quality Yoshi as to be expected. What was unexpected was how much more fun the exhaust made the ADV150. It is silly to have a aftermarket exhaust on a 150cc scooter, but it does add some character to the scooter.Sound is a low rumble at idle, mostly noticeable when indoors. Typical single sound when revved up, not obnoxious loud, just reasonable.Looks clean and tidy on the bike, makes it look more sporty. Exhaust also frees up one mounting hole on the swing arm. I attached a unused Oggy Knob there to protect the new exhaust.View Detail
Excellent. Exceeded my expectations. It really is a beautiful piece of engineering that can't be done justice in the photographs andbe dine iimpressive the ampount of care they put into making it.Installation is straightforward and can be done in well under an hour. The only thing needed to do is to loosen the footpegs so you can thet the original muffler out and the new one in. The instructions are in Japanese but the diagrams are sufficient. There was a buring smell but that's just the rust inhibitor burning off and it quickly went away. This is normal.The sound is distinctive and sounds like an aftermarket exhaust. About 30% louder and brings a a beautiful single piston 'thumper' sound to the bike. I can't comment on accurately performance but it definitley sounds faster.View Detail
Just ordered the SS version! I was worried that the aftermarket Thailand foot pegs would get in the way but it appears as if the exhaust mount is in a different location- we’ll see!
You know it is a high quality, well-made sticker once you pick it up. Very solid and and thick, and its OEM item, well worth for decorating your bike.View Detail
The order was confirmed one months ago and suppose delivery on Sept. I am very happy that webike can managed to delivery my order one month earlier. The Swing arm are beautiful! Can't wait to install it on my Grom! Rear wheel included, high quality!View Detail
It is a big upgrade for the grom. But I never doubt the level of craftsmanship from Yoshimura. The installation is not easy, but it is manageable. Strongly recommended! View Detail
The delivery was fast, arrived my house within 5 days since the order was confirmed. Good quality and nicely protected. The stickers are beautiful as well!View Detail
Brought this product few months ago, it functions well and fit nicely on my grom! No problem riding my bike on highway at all! The fixing are nicely designed and hey, its Daytona, nothing to worry about.View Detail
