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.
