Kooks Custom Headers

You can't have a conversation about high performance headers and exhaust systems without bringing up Kooks. Kooks Headers and Exhaust has been at the top of the list since the 60s, helping racers of all kinds "Get Kookin'." Whether it's a car built for the drag strip, road course or circle track, Kooks custom headers have proven to greatly improve the performance of vehicles of all kinds.

Lethal Performance first started using Kooks custom headers back in 2005 when it was time to upgrade the headers on our 2003 Cobra to help support higher power levels. Over a decade later, we looked to Kooks once again when we chose a longtube header setup for a 2016 Shelby GT350. Needless to say, the quality, sound, power and overall system fit of Kooks Headers blew us away and continues to impress.

At Lethal Performance, you can find Kooks longtube and shorty headers, midpipes, catbacks, axleback muffler systems and more. All are made from high grade T304 stainless steel and can fit most model year Mustangs and Ford trucks. Find the perfect high performance headers and exhaust systems for your vehicle here!
