Kooks specializes in high performance exhaust systems for domestic cars and trucks. Kooks manufactures exhaust systems ranging from Custom built headers for race applications to bolt on systems for production cars.
These headers were designed to bolt directly to your existing KOOKS X-Pipe. But, the added benefit is that if you have a KOOKS compatible exhaust, such as SOLO w/KOOKS connections, or a CORSA w/KOOKS Connections, mating these to your setup should be pretty simple. Please keep in mind, if you are mixing brands, there may be slightly more work than just a bolting it up, but nothing too crazy.
Best investment by far. Had them ceramic coated could tell the car was breathing better even before the tune.
