Long Tube Headers:
Air Injection:
The headers are designed to retain the factory air injection giving you provisions for all factory emissions equipment.

Formed Collectors:
4-to-1 formed collectors decrease turbulence and increase exhaust velocity. The result is increased horsepower, torque and improved throttle response.

Laser-Cut Header Flanges:
High quality laser-cut header flanges provide superior sealing at the head surface.

Connection Pipes (Street):
High-Flow Cats:
This system includes dual, high-flow, metallic, 400 cell per square inch, stainless steel catalytic converters for maximum flow and performance.

Factory Mounting Locations:
3" diameter connection pipes mount directly to OE mounting locations.

Mandrel-Bent Tubing:
This system is constructed of mandrel bent, stainless steel tubing for maximum performance, corrosion resistance, and strength, eliminating cracking.

MIG Welded:
This system comes 100% MIG welded by certified craftsmen for race proven strength and durability. MIG welding provides the strongest welds reducing stress cracks.

    In recent testing, the Street Version produced +33 HP and +30 lbs. x ft. TQ on our in-house dyno (tested on a 2014 Toyota Tundra V8-5.7L).
