Pro Circuit Ti-4R Exhaust System

Pro Circuit’s flagship closed-course exhaust system, the Ti-4R ($999.95), is now available for KTM 250, 350 and 450cc SX-F motocrossers. This three-piece titanium design features an RC-4 resonance chamber to reduce noise emissions and meets the AMA Pro Racing sound cap of 94 decibels. Also available: The likewise-race-only T-4R ($779.95), with its stainless-steel header pipe, and the off-road-approved T-4 ($779.95), which comes with a removable USFS-approved spark arrestor and race muffler tip.
