Two Brothers M-2 Flange-On Exhaust Motorider - Mountain View, CA, USA Two Bros M-2 Flange-On Exhaust for Honda CBR 929RR "The Two Bros M2 Flange-on after market muffler was extremely easy to install. It is well engineered utilizing the factory design. It took less than 30 minutes from start to finish including; 1-removing the stock muffler (loosening and removing the 3 socket head bolts that secure the muffler to the stock pipe and removing the stock muffler hanger bolt from the RH RR passenger footrest).2-cutting down the exposed stock exhaust diffuser (I used a sawzall which was quicker and easier than a hacksaw), 3-positioning the Two Bros muffler and aligning the 3 flange bolt holes, 4-installing and positioning the supplied muffler hanger bracket, 5-then tightening all fasteners. Fit and finish of the Two Bros muffler was superb. It is sleeker and better proportioned than the stock muffler. I purchased the system in the carbon fiber material which had a unique "diamond" pattern with CNC aluminum gold anodized inlet and outlet finished off with a black magnesium end cap. I also purchased a gold power tip, stainless spark arrester, and gold finished end cap bolts from Two Bros giving it a distinct customized look.The only complaint I have is the end cap bolts are made from aluminum and extreme care must be taken to prevent them from stripping out when torqueing them down. In addition, the bolts exhibit a flat satin finish and not shiny gold chrome as shown in the pictures. The sound is amazing with a deep throaty pitch without the high pitched screech you generally hear with other after market systems under extreme acceleration! I was also pleasantly surprised to feel a slight power increase, although this may be a result of a less restrictive exhaust and freer breathing system."
