Product Description

If you want high quality, look no further than Kooks Custom Headers. These are some of our favorite headers to install on any vehicle, simply because if they’re called Kooks, you know they’re going to fit great! Made of extremely high quality stainless steel. These are the perfect upgrade for the stock manifolds, which tend to crack and leak over time. The 1 5/8″ header flows better than stock, freeing up power. Check out the DYNO results HERE. Good for 11 rwhp and 16 ft/lbs tq when we tested on our dyno. Pair it with our mail order tune to maximize results! Available with a green catted connection pipe, high flow catted connection pipe, or off road y connection.
