The entire line of Two Brothers Racing’s
M-Series canisters feature the highest level of quality
construction and are designed to be fully serviceable
in the event of damage, routine maintenance or the
occasional repack.
Two Brothers Racing’s M-series spring-mounted slipon
canisters all feature our patented and exclusive
lightweight, thinwall, die cast aluminum 1-piece inlets
and outlets. Our flange-on systems and patentpending
V.A.L.E.™ exhaust systems feature CNC
milled billet aluminum inlets and outlets. These special
designs provide for lighter weight, greater strength,
ease of maintenance and simplified construction,
which is what a premium performance product is all
about!
The exhaust note produced by all of our Absolute 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.

V.A.L.E.™ System
The V.A.L.E.™ system is Two Brothers Racing’s revolutionary and patent pending method of
attaching our muffler canisters to the exhaust tube without the use of springs or welding.
Our V.A.L.E. systems allows the muffler assembly - exhaust tube and canister - to be positioned
perfectly on the bike before all the mounting hardware is fully tightened. Once the canister and
exhaust tubes are properly aligned, the V.A.L.E. assembly locks the muffler canister to the exhaust
tube assuring a perfect, leak-free fit.
This system is simple and easy to install, requiring nothing more than a 5mm hex wrench, which is
included with every one of our exhaust systems.
The X-Lite ring is the next step in the evolution of V.A.L.E. technology. CNC milled from 6061-T
aluminum, the design of our X-Lite ring efficiently and elegantly removes all unnecessary material
from the coupling. This reduces the weight of the part while still maintaining its structural integrity.
