Kooks 1-5/8 in. Long Tube Headers & Off-Road X-Pipe Combo (05-10 GT)

Improves Rear Wheel Torque and Horsepower. This Kooks 1-5/8” Headers and Off Road X-Pipe Combo eliminates restrictive factory cats and introduces throaty, free-flowing tubing that helps your Mustang’s engine breathe better. This quality engineering and construction provides instant power gains and an outstanding basis for further tuning. The inlet ports of the long tube headers are hand ground at Kooks to ensure perfect, restriction-free fitment.

Racy, Raspy, Big-Bore Sound. The wide-mouthed, tubular Kooks Headers and optimized cat-less x-pipe work with the firing pulses of the engine to harness extra power and produce a raspy, racy exhaust note that builds to a real scream. With the increased volume, nobody will mistake your Mustang for stock.

Cat-Less Design. Kooks Off-Road X-Pipe is constructed from cat-less down pipes that mate up to the Long Pipe Headers. There are no more factory cats to get in the way of exhaust gases and choke off your Mustang’s real power.

Handcrafted Stainless-Steel Components. Kooks Long Pipe Headers are constructed by hand from the finest 304 stainless steel and feature mandrel-bent smooth-radius curves and hand-ground inlet ports to eliminate all possible obstructions. They’re complemented a durable stainless-steel x-pipe.

Tune Recommended. Installation of the Kooks Headers and Off Road X-Pipe makes a huge difference to the breathing of your engine. To harness the full benefits, ECU calibration is recommended.

Application. The Kooks 1-5/8” Headers and Off Road X-Pipe are specifically engineered for 2005 through 2010 Mustang GT models.
