 | White Brothers Carbon Pro Exhaust System
....The world renowned Carbon Pro exhaust was conceived with no boundaries or limitations to its existence and with only one objective, to be hands down the best exhaust in the world. Designed by our in house R&D Department and with the help of both the Factory Yamaha and Honda Team’s to do development, this exhaust has easily become that. It is the only exhaust to have a perfect 24 for 24 season, has won more races on a 450 than any other exhaust ever and swept all 3 podium positions in Supermoto at the 2005 X-Games. The looks are with out question above and beyond what had or has been done. Quality is second to none and above all it is the most hi-performance race exhaust as proven by the record amount of race wins and magazine tests it has won.
....Don’t believe us, then ask one of these riders who have tested and raced the Carbon Pro: Chad Reed, Ricky Carmichael, Jeremy McGrath, Doug Henry, Kevin Windham, Heath Voss, David Vuillemin, Tim Ferry, Andrew Short, Mark Burkhart, Ernesto Fonseca, Ben Bostrom, Nathan Ramsey, Nicky Haden and Travis Preston.
.... Transworld MX magazine gave it a score of 9.5 out of 10, stating “just gobs of smooth power” and also saying “torque and bottom end pull were substantially stronger with no loss on top (in fact, our CRF test bike actually gained some over rev), making the Carbon Pro a great aftermarket exhaust choice”. Thanx Transworld, we couldn’t have said it better ourselves.

White Brothers is proud to introduce this incredible new addition to our performance exhaust line-up! The XCR offers unmatched quality, performance and versitility at an amazingly affordable price.
As with all White Brothers exhaust the XCR puts out the power that would only be expected by the industry leader and innovator in 4-stroke exhaust. This exhaust allows you to ride in the forest with a spark arrestor at 96 db and then take the same exhaust out to the track or in a riding area where a spark arrestor and 96db is not required. It has diversity and performance at a price not met by the competition. Using our exclusive “square ellipse” aluminum exhaust canister plus stainless steel exhaust tubing, the XCR exhaust is the best buy for the price.
Our In-house R&D team has achieved the impossible.

 | White Brothers E2 Silencer
The E2 Slip-on muffler was designed exclusively for those who like to ride the trail while also have hitting up their local track, all while using the same exhaust. The “square ellipse” shape was specifically designed for its superirrior silencing capabilities. In fact this shape has become the foundation of our complete line of full-size exhaust systems as used over the past 4 years by the factory Yamaha and Honda teams.
Created to be able to meet the US Forestry sound requirement of 96 db and have a spark arrestor. While also having the option of running it with a more open tip for track use that can be changed with the turn of one screw in a few seconds.
This is an exhaust that set the bar and still stands alone as the leader for a muffler which can be used for either the track or the trail with tune ability, performance, durability and quality not met by our competition. Again using a revolutionary impact extruded one piece aluminum canister/end cap plus stainless steel exhaust tubing, this is the exhaust that will give you what is needed to enjoy off road motorcycle riding of all kinds.
