The tubing is mandrel bent to maintain a consistent internal diameter through bends, optimizing exhaust flow and minimizing backpressure for better engine efficiency.

The tailpipe and exhaust tip feature a high-heat black powder coating that withstands extreme temperatures and resists chipping or fading, giving your Jeep a bold, aggressive appearance. The remainder of the system is finished in a mill state to better endure the harsh conditions of off-road driving, reducing visible damage from rocks and debris. Fully sealed seams prevent rust formation, ensuring long-lasting performance and reliability.
