Two Brothers offer three distinct canister shapes to choose from; Standard Oval (C-2, C-7 or M-2), Traditional Round 4.5” diameter (C4) and Large Oval (C-5 & M-5). All of the canisters perform and sound the same, they are simply different shapes. They all incorporate Two Brothers exclusive technology and premium construction material. The different exterior shapes allows you to choose the one that best fits the style of your motorcycle. For instance most people prefer the C-2 / M-2 (Standard Oval) with smaller sized motorcycles (like 600cc machines) while others prefer the C5 / M5 (large oval) with larger sized motorcycles (like 1000cc machines). For those who prefer round canisters we offer the C4 (round). 

M-2	C-2	C-4	C-5

   The entire line of Two Brothers M & C 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), routine maintenance or the occasional repack. Two Brothers Racing’s M & C series spring-mounted slip-on canisters all feature our patented and exclusive lightweight thinwall die cast aluminum one-piece inlets and outlets. Two Brothers 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 Two Brothers Exhaust is best described as being deep and throaty without suffering from the shrill whine normally associated with other manufacturer's straight through muffler canisters.
