Two Brothers Racing M-2 Slip-On Exhaust Systems - Yamaha R1 (2007-2008)

Designed and built with painstaking care and attention to detail, Two Brothers Racing is proud to release our Dual M-2 Slip-on exhaust system for the 2007 Yamaha R1, available with either aluminum, titanium or high-temp carbon fiber canisters.

The entire line of M Series canisters feature the same high level of quality construction and are designed to be fully serviceable in the event of damage (replacement parts are available, please call us), routine maintenance or the occasional repack. Two Brothers Racing’s M series spring-mounted slip-on canisters all feature our patented and exclusive lightweight thinwall die cast aluminum one-piece inlets and outlets. Our V.A.L.E. (patent pending) slip-on exhaust systems and flange-on systems feature CNC'ed aluminum inlets. These special designs provide for ease of maintenance as well as simplified construction, which is what a premium performance product is all about! The exhaust note produced by all of our Top Level exhaust systems is best described as being deep and throaty without suffering from the shrill whine normally associated with other manufacturer's straight through muffler canisters.

The V.A.L.E.™ inlet design eliminates the use of springs and creates an adjustable mount that is solid when fixed in place. The system also features a thinwall s-bend tube that connects to the factory header pipes.

The M-2 Canister has a smaller Oval shape than the M-5

•  M-2: Width: 3.75" Height: 4.85"
