In recent dyno testing, this race pipe produced 13hp and 29lbs. x ft. torque and outflowed the factory down pipe by 287%. This system uses a 4" diameter tube and progressively tapers to increase exhaust velocity and usable torque. This high performance race pipe is constructed out of lightweight, TIG-welded 4" stainless steel.Note: Does not fit vehicle with N26 engine. N26 engine is SULEV (super low emission) version of N20 Tig-Welded: 100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks. Tapered Design: A unique 4" tapered design is used to increase exhaust velocity and increase usable torque. This means more aggressive throttle response and increased passing power. Factory O2 Sensor locations: This down pipe uses factory mounting locations for the O2 sensors. Hassle-Free Installation: All hardware and brackets are included for a hassle-free installation. This unit also comes with a lifetime warranty. aFe down pipes are engineered and manufactured in our Corona, California manufacturing facility.
