Really Big Bore Performance. The Kooks 1-78” x 3” Mustang headers have that big meaty bore that maximizes the flow of exhaust gases from the head of your 4.6L V8 for serious high-power applications. The primary bore is so big that Kooks recommends using the Flaming River Steering Shaft (not included).

Big, Big Burble and Roar. With headers the size of these 1-7/8” babies, you know you’re going to enjoy the sound. Whether it’s the serious race sound pinging off the pipes at the head or the huge-throated roar from the outlets, the noise is going to be big once you bolt these on.

Eliminates Factory Cats. The 1-7/8” x 3" Mustang Headers must be used with Kooks connection pipes so the stock cats are eliminated. Straight-through and catted connection pipes are available.

T304 Aviation-Grade Stainless-Steel. Kooks produces its headers from the best T304 aviation-grade stainless steel. The flanges are laser-cut 3/8” stainless steel for maximum strength. These are the best you can get.

Recalibration Required. These huge headers radically alter your engine’s breathing so you’ll need tuning to get the best out of them. The included EGR and O2 sensor extensions help to optimize performance and emissions.

Not CARB Compliant. You cannot use these headers anywhere in California. They are not CARB compliant.

Application. The 1-7/8” x 3" Long Tube Headers fit the 1996 to 2004 Mustang Cobra and Mach 1 models.
