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.

Two Brothers dual exahaust for my 06 ZX10R

The installation was easy. took all but an hour and a half to complete.

The sound was exactly what I was looking for-- a deep growl.
and loud enough to be heard but not too obnoxiously loud..

The look is spot on.. Highly recommend

A: This exhaust should be quite simple to install. You would just need to unbolt the stock muffer and then bolt this muffler up in its place. The exhaust will also come with detailed instructions for installation.
