Outstanding Carbon Exhaust System for the Grom
About quality and texture: I am happy with the quality of the full exhaust system S1R carbon silencer from Two Brothers Racing. Made up of a two piece stainless steel exhaust pipe that connects to the carbon fiber sleeved and machined aluminium end capped muffler. About the feeling of use: Premium looking exhaust for the Grom with its gloss finished carbon twill and a well proportioned exhaust pipe that increases power with a deep exhaust sound. Products to buy together: A higher flow air filter panel that fits the OEM Honda airbox would also be desirable to purchase alongside the the full exhaust system S1R carbon silencer to help with performance. Difficulty of installation: The process to install takes about one hour to complete. Remove the head stud nuts and frame mounting bolts to remove the OEM Honda exhaust. For a leak free install I like to use a high temperature silicon sealant at all the slip joints and torque down the head stud nuts and two frame bolts. Cost performance and comparison with other products: Very high costing but you are receiving a high quality manufactured product using quality stainless steel and carbon fiber materials that will increase performance as compared to just a slip-on exhaust mufflers that retains the Honda exhaust pipe. About shipping and packaging: Sea frieght was my preferred method of shipping due to the lower cost but currently this service is unavailable from Japan Post, EMS is much faster which is nice. 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: Along with the high temperature silicon sealant for installation I would also advise on a new exhaust gasket to ensure zero exhaust leaks.

Two Bros Racing S1r Full Exhaust Black Series
I purchased this Two Brothers Racing S1r full Exhaust in Black Series Carbon for my 2016 Yamaha R3. The muffler is super light and is one of the best looking examples on the market. The installation was straight forward and I was able to put it on by myself in my garage in about two hours. The sound and performance gains have been great. A fuel tune is necessary to get full performance out of this exhaust, but it’s well worth it. View detail
Explosion
It looks like Large change SMART than OEM lunch box
Match the color of CeramicBlack to the car body
Is it wonderful?
The sound is very explosive
I felt like I heard it in pre-purchase videos etc. Large Looks durable
I thought it, but it is a quarrel when I actually hear it
TBR made famous for explosive but this series too
It is a feeling that said it told to not miss an example
I have baffle for Japan but it's annoying
Although I hate explosion, those who want to attach this Exhaust System
It may be necessary to devise

feel well.
Since there are not many people installing it, it is good not to get cued at the touring destination. As for the performance, I can not say anything because it is not easy to put in. As a good point, it is light weight, that the style of Right Side is tightened and became fearless, almost volume so the volume is large Large Material : Because it is Stainless Steel, it has lighter sound quality than NORMAL.
Manual version can not be installed with English version because it is made in United States. It takes time to remove the Normal muffler and also to wear the Custom Exhaust also needs to get caught.
