We offer two distinct canisters hap es to choose from; small oval (M-2 and M-5). Both of the canisters perform and sound the same, they are simply different shapes. They all incorporate our exclusive technology and premium construction material. The different exterior shapes allows you to choose the one that best fits the style of your motorcycle.

V.A.L.E. = Variable Axis Locking Exhaust The V.A.L.E.™ system is our revolutionary and patented 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 tot he exhaust tube assuring a perfect, leak-free fit.

Regardless of sleeve material or shape,all of our canisters perform and sound the same. We manufacture our exhaust systems from different materials to allow you to best match our canister to your bike.

Polished/Brushed Aluminum Fiber Carbon Titanium
Aluminum is a very lightweight and strong material used extensively in the aerospace, automotive, and of course,motorcycle industries. Aluminum is a wise choice due to its excellent strength to weight ratio, corrosion resistance, and clean look. We use lightweight thin-wall .060” extruded 6061 aluminum alloy that is heat treated to a T-6 condition for increased strength, durability, hardness,and finish hold. After the aluminum has been heat treated, it is cut to length and given a brushed satin or polished finish depending on bike application. Ounce for ounce aluminum is the best value of all our M Series mufflers. As a rule our aluminum mufflers weigh about 8.3oz. more than Titanium and Carbon Fiber mufflers. We have been using Carbon Fiber in motorcycle mufflers since 1992. We are currently the only US Company to exclusively use Filament Wound Carbon Fiber (FWCF) on every carbon fiber muffler we sell. We draw on only the best high temperature resins, and control a proprietary lining system adopted from spacecraft, for additional heat resistance. Our FWCF is continuously wound over a precision machined mandrel for a 100% seamless bond. The FWCF tube is then cured in a high temperature autoclave oven for superior strength and heat resistance. These crucial elements meld to form a precision lightweight muffler that will perform as well as it looks. By weight titanium is one of the world’s strongest readily available metals, making it ideal for our M series mufflers. It is 45% lighter than steel with comparable strength, and twice as strong as aluminum while being only 60% heavier. That’s right titanium is HEAVIER than aluminum, but since it is twice as strong we are able to use very thin (.024”) material to construct our Titanium muffler. The result is a muffler that is about 8.3oz. lighter than our M series aluminum mufflers. Titanium has become an industry standard for motorcycle mufflers due to its durability, corrosion resistance,lightweight, and factory look.
Slip-on Systems Flange-On Exhaust Systems Full Systems
This type of system replaces your existing “s-bend” pipe and exhaust canister. Our s-bends are manufactured from .035" thin wall stainless steel. We then polish them to a satin finish. We use only #304 stainless which will never rust.
After a few heat cycles the steel turns a golden amber color which is the characteristic signature of high quality stainless steel.
These systems not only adds horsepower but also can drop significant weight from your bike. This type of canister can be mounted in the original canister position or in a “high” mounted canister position depending on the bike and our available applications.
This canister bolts to your existing exhaust system directly replacing your stock muffler. You retain your original headers and "s-bend” pipe. This configuration not only adds horsepower but also can drop significant weight from your bike.
Reinstallation of the stock muffler, should the need ever arise, is very simple. This type of canister can only be mounted in the original canister position regardless of the bike.
This system completely replaces your existing exhaust system. This not only adds horsepower but also can drop significant weight from your bike. We build our header systems as a complete unit.
Our finished system flows better at the collectors, makes more power and does not vibrate on the bike.
Our super bike stainless steel headers are manufactured from .035" thin wall stainless steel. We then polish them to a satin finish. The ductile quality of stainless steel makes it possible to produce extremely light and strong headers. We use only premium #304 stainless which will never rust and after a few heat cycles will turn a golden amber color which is the characteristic signature of high quality stainless steel. This type of canister can be mounted in the original position or in a “high” mounted position depending on the bike and our available applications.
