Kooks Universal 2in x 4in Merge Coll w/9-10in Long Body. Plus 2in for Slip

Kooks Headers has been a big name in high-performance exhaust for over 50 years, known for building parts that win races. This universal merge collector is a great example of their work, designed to help you get the most out of your custom exhaust setup. It takes the exhaust gases from four primary tubes and smoothly merges them into a single 4-inch outlet, which is key for maximizing power and improving exhaust scavenging.

This collector is constructed from T304 stainless steel, a well-built material that holds up well against exhaust heat and corrosion. It features a 4-into-1 design with a 2-inch inside diameter inlet that slips over 2-inch primary tubes. Kooks also includes their patented scavenging spike inside, which helps direct exhaust flow and can improve overall engine performance. The outlet is a 3-1/2 inch merge that transitions to a 4-inch outside diameter. It also comes with two A/B style tabs to help secure it to your primary pipes during fabrication.

This part is intended for custom exhaust fabrication and is sold individually. Remember that this collector is not CARB approved and cannot be shipped to California.
