Kooks Headers and Exhaust company are at the top of the list when speaking about high performance headers and exhaust systems for your car or truck. They've been in the business since the 60s helping racers of all kind. Whether it's a car built for the drag strip, road course or circle track Kooks custom headers have show to greatly improve the performance of your vehicle. Kooks offers both longtube header and shorty headers, midpipes, catbacks and axleback muffler systems which are all made from high grade T304 stainless steel.
Lethal Performance started using Kooks products back in 2005 when it was time to upgrade the headers on our 2003 Cobra to help support higher power levels. We equipped that car with a set of Kooks 1-7/8" longtube headers along with a 3" offroad midpipe and had excellent results helping the car to make 879rwhp. Our next set of Kooks longtube headers went on our 2008 Shelby GT500 that ran a Whipple supercharger. The Kooks 1-3/4" longtube headers we put on that car fit perfect and helped support the upper 700rwhp range.
Moving along to our newest car, a 2016 Shelby GT350 we looked to Kooks once again for a longtube header setup. Since the GT350 had a Whipple Supercharger on it we wanted to get the most flow and performance from the exhaust side. We decided on the Kooks 1-7/8" stepped longtube header setup along with their matching 3" offroad midpipe and their catback exhaust system. This was our first time using their complete system with mufflers. To say we were impressed is an understatement. Their full system fit perfect, sounds amazing and helped us make big power. These are the reasons why Lethal Performance will continue to run Kooks custom headers on our cars as well as recommend them to our customers.
Kooks offers high performance longtube header and exhaust systems for most model year mustangs as well as ford trucks. Whether it's a Mustang GT, Mustang Cobra, Shelby GT500, Boss 302, Shelby GT350, S550 or an S197 Kooks Custom Headers has what you're looking for.
