Kooks 1-3/4-Inch x 3-Inch Long Tube Headers; Stainless Steel (05-10 GT)Find parts that fit my vehicle

Get the Breathing Your 4.6 Really Needs. Capable of supporting tunes up to 750 horsepower and beyond, the Kooks 1-3/4” x 3" Long Tube Headers are built to bolt straight on, liberate huge power, look great and sound spectacular. With precision hand-ground inlet ports, laser-cut 3/8-inch two-bolt flanges, and Kook’s unique scavenging spike, these gorgeous bundles of power bolt perfectly to your heads, won’t warp or bend, and optimize gas flow through smooth, carefully constructed passages to let your V8 Mustang really show its stuff.

Big, Bad Burble. The Kooks Long Tube Headers don’t hold back. The tubular construction, big inlet tubes and 3” collector conspire to produce serious sound. From idle to high revs, these headers ensure furious power gets out.

Deletes OEM Cats. These headers have to be used with a Kooks X-Pipe or H-Pipe. OEM catalytic converters are deleted so your car can only be used off-road, not on the highway, and will not be emissions or CARB compliant.

Hand-Made T304 Stainless-Steel. These Kooks Long Tube Headers are hand-assembled from aircraft-grade stainless steel. They look as good as they sound and will do so for years.

Calibration Required. Installation of these Kooks Headers deletes the factory cats. Tuning of the car’s ECU with the included O2 extensions fitted will be required. Cars with automatic transmission will need extra O2 extensions.

Application. These 1-3/4” x 3" Long Tube Headers fit 2005 to 2010 Ford Mustang GT.
