Construction & Design

Crafted from premium stainless steel, these long tube headers and mid pipes are engineered to withstand the rigors of high-performance driving while resisting corrosion for long-lasting durability. The 1-7/8" primary tubes strike an ideal balance between maximizing exhaust flow and fitting within the engine bay constraints.

Mandrel bending technology ensures smooth radius bends that reduce turbulence and backpressure, enhancing exhaust scavenging efficiency. Each weld is precision TIG welded to provide structural integrity and a clean, professional finish. The integrated high flow catalytic converters in the mid pipes maintain emissions compliance without sacrificing power.

Performance & Sound

By replacing restrictive factory manifolds and mid pipes, this Stainless Works system significantly improves exhaust gas evacuation, resulting in noticeable gains in horsepower and torque. The long tube header design enhances low and mid-range torque, improving throttle response and acceleration.

Additionally, the system produces a deep, aggressive exhaust tone that enhances the driving experience without excessive drone, making it suitable for both spirited street driving and track applications.
