Supersprint Sports Catalyst Bypass tubes perfectly mated to the manifold / header exhaust ports for smooth gas flow. Length and diameter are tuned to engine displacement and power-band characteristics. Each product is developed and extensively tested using the exclusive MAHA 4x4 LPS 3000 braked to produce the best power results.

CNC machined head flanges, heavy duty 7 to 12 mm thick steel, and heat distortion resistant.

Stainless steel tubes (for Cat. equipped models), or chrome plated, heavy duty steel tubes, 1,5 mm wall thickness, mandrel bent with CNC bending machines.

Joints between tubes are hand welded. Slide-on type connections are machined to perfect tolerances for leak proof fitting.

An oxygen sensor is retained, where present in the OEM exhaust (no modification is needed to the engine management system).
