FULL EXHAUST SYSTEM HIGHLIGHTS:
Configuration
4-2-1 or 2-1 collector systems are designed for maximum horsepower and torque increases and the efficient delivery of those gains throughout the RPM range.

Merge Collectors
The key to an efficient system is in the merge collectors. At Two Brothers Racing, our collectors are hand made, 100% TIG welded and optimized for high flow and velocity. A variety of collector lengths, diameters and shapes are used based on application and performance goals for particular models.

Crossover Tubes
Just like all exhaust system components and configurations, the integration of crossover tubes is implemented into Two Brothers Racing exhaust systems only when a performance increase is found through comprehensive track and dyno testing. In some cases, crossover tubes hinder engine performance. You will only see a crossover tube on a Two Brothers Racing exhaust if performance is enhanced.

Mandrel Bent Tube
All Two Brothers Racing systems are created from .035 304 Stainless Steel or the finest quality CP grade 2 Titanium precision bent via our CNC Mandrel Bender with exacting bend tolerances of 0.1 degrees. Headers are mirror polished for a custom finished look.

Stepped Headers
At Two Brothers Racing we only use tube diameter transitions from smaller to larger when it meets our performance criteria checklist. The size change can increase power in one area of the powerband and then sacrifice it in another. Steps in header pipes are carefully placed and thoroughly tested in most Two Brothers Racing 4-2-1 systems but only when performance is enhanced across the board.

CNC Machined Flange Collars
CNC Machined Exhaust Port Flange Collars are precision cut from solid chunks of Billet Stainless Steel or Aluminum to provide a precise, leak free fit.

CNC Machined Aluminum Flanges
CNC Machined from Billet 6061-T6 Aluminum and hard anodized for durability and style. Our Flanges are designed extra thick to eliminate warping and bending under extreme temperature conditions.

Spring Fit Joints
Slip connections are secured with Stainless Steel swivel-hook springs to provide vibration damping, reduce header fatigue and eliminate cracking. They also allow for simplified installation.

Two Brothers Racing M series exhaust 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. V.A.L.E.™ slip-on/full exhaust systems and flange-on systems feature CNC machined aluminum inlets and outlets. 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 Racing's 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.™ Fitment (Variable Axis Locking Exhaust)
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. Two Brothers Racing V.A.L.E.™ systems allow 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 Two Brothers Racing's exhaust systems. The X-Lite™ ring is the next step in the evolution of V.A.L.E.™ technology. CNC milled from 6061-T6 aluminum, the design of Two Brothers Racing's 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.

Strength from Within
Not all cores are created equal. At Two Brothers Racing mufflers are engineered from the core to the cap. We use a stainless steel wound, perforated and corrugated core on all Two Brothers Racing systems. Core diameter and length varies depending on model needs and the desired performance characteristics. Our Stainless Steel Spiral Core is lighter than traditional cores of the same material and even some of our competition’s titanium cores. The Spiral Wound process delivers a 2dB sound decrease, further enhancing our uniquely deep sound attenuation.

CANISTER MATERIALS
Note: All canister materials deliver equal performance with their own unique look.

Carbon Fiber
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 utilize 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.

Titanium
By weight titanium is one of the world’s strongest readily available alloys, 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 or C series aluminum mufflers. Titanium has become an industry standard for motorcycle mufflers due to its durability, corrosion resistance, light weight, and factory look.

Polished Aluminum
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 durability. After the aluminum has been heat treated, it is cut to length and polished to a mirror finish. Ounce for ounce, aluminum is the best value of all our M & C Series mufflers. As a rule, our aluminum mufflers only weigh about 8.3oz. more than our Titanium or Carbon Fiber mufflers.
