Introducing the all-new 2007-2012 Jeep JK Wrangler Axle-back exhaust system by Road Race Motorsports. After months of tuning and designs, we are now in production and ready to offer this new axle-back exhaust. RRM dyno-tuned this exhaust to maximize power on both the 3.8-liter V-6 and a variant for the 3.6-liter Pentastar Engine (specify what year you have when calling). It will excel at its best with our Stage 2/3 JK POWER PACKS (patent pending.) RRM has brought out the best in these drivetrains. See our site for details.

This axle-back system is fully hand-fabricated and TIG-welded here in the U.S.A. We then take it a step further and have it fully nickel plated for a full 100% coating to resist the harsh elements. You can expect a nice, smooth tone along with added performance throughout the powerband. Guaranteed not to make a droning sound. Other exhausts out there sound like a 4 cylinder and bother drivers at cruise speeds.

Two Brothers Racing, a leader in American-made and engineered performance exhaust systems, announces the release of its 2011 Polaris RZR900XP Dual M7 Full Exhaust Race System.

This all new dual system is 5 lbs. lighter than stock and the performance gains are remarkable! They can be seen and felt in every part of the powerband. We are sure that when you pull this exhaust system out of the box, install it on your UTV, and feel the performance you will agree that it is The Absolute Top Level. Through extensive testing and racing developments we have produced a winning combination of Top Level Performance with our new RZR Dual M-7 Exhaust System.


Two Brothers Racing’s new RZR900 systems feature the same high-quality components, materials, design and construction you’ve come to expect from the Absolute Top Level supplier. Get up close and personal with these new systems at your local TBR Dealer, log into www. twobros.com or call 800.211.2767
