KTM Exhaust

A staple in the racing community, Pro Circuit is expanding an already reputable line of exhaust systems with the addition of multiple KTM applications.

Now, the owners of KTM 250, 350 and 450 SX-F motorcycles will be able to enjoy all of the industry-leading style and performance gains found in every Pro Circuit exhaust system sold.

Consumers will be able to choose from a diverse line of systems offering a variety of performance enhancements depending on their budget and type of riding. The flagship system is the Ti-4R, which features lightweight, three-piece titanium construction including the RC-4 resonance chamber to reduce noise output.

Built from the same mold as the Ti-4R comes the T-4R. This system provides the same performance gains as the Ti-4R system but is constructed from quality stainless steel and aluminum. Both the Ti-4R and T-4R systems meet AMA 94dB sound requirements and are designed for closed course competition.

Still equipped with the RC-4 resonance chamber the T-4 Exhaust system features aluminum and stainless construction, a removable USFS-approved spark arrestor, and is guaranteed to provide a lightweight yet durable exhaust system.

Rounding out the new KTM applications is the T-4S exhaust. Featuring a slip-on design, this easy to install and lightweight exhaust offers increased performance at an affordable price.

Each of these exhausts comes complete with an extra silencer packing kit. Additional product specifications are below. The Ti4-R, T-4R, T-4, and T-4S exhausts are now available online or at a dealer near you. Please visit procircuit.com to purchase this system and check out other products made by Pro Circuit.
