Allows the biggest torque gains for faster acceleration and maximum hauling power
If you haul or tow large loads or want to dominate the street scene, drag strip or hill climb, this is the system for you
Includes everything you need to replace your stock system after the turbo
Designed to allow your engine to breathe freely to get the maximum horsepower and torque it can produce — significantly better than stock or 4"" performance systems. 4"" down pipe after the turbo — the largest diameter possible for clearance — with the bottom of the down pipe expanding to 5"". Mandrel-bent 5"" pipes eliminate restriction. Free-flow double-wrapped muffler with 5"" core. Aluminized 16-gauge steel construction resists corrosion to last for years. Side exit behind rear wheel. Not recommended for use on stock engines. Truck must have a performance air filter or air intake kit and a power computer chip or programmer of some type (engine filters, intakes and ignition systems sold separately). Will not fit trucks with a factory-equipped catalytic converter (except where noted). Kit includes all clamps, hangers, hardware and instructions. Note: Dodge and Ford models with shorter wheelbases will require cutting of included connector pipe (cutting instructions included)."
