Product Details
Kooks Headers has been a leader in high-performance exhaust for over 50 years, known for crafting parts that maximize power. This 3-inch Y-pipe is specifically made for your 2007-2018 Jeep Wrangler JK 4-door when you've swapped in an LS engine. It's designed to connect seamlessly with Kooks headers and cat-back exhaust systems, ensuring your LS swap breathes freely and performs at its best.
This Y-pipe is constructed from 304 stainless steel, which is strong and resists corrosion. It features Kooks' GREEN catalytic converters, which are 300-cell high-flow units designed for maximum power output without sacrificing emissions compliance in most areas. The inlet connections use a Torca Swivel Seal style for a secure and leak-free fit. This Y-pipe is intended to be used with Kooks Headers part numbers 37102200 or 37102400, and connects to Kooks cat-back exhaust part number 37104100. It's designed to work with LS engine swaps using kits like the RPM Extreme LS Swap Kit.
A minimum 2-1/2 inch suspension lift is recommended for proper clearance. For 2-door models, you might need to relocate the fuel tank. Because this is a custom setup for an engine swap, other parts may be required for perfect fitment. It's a good idea to contact Kooks Headers and Exhaust before ordering to ensure you have everything needed for your specific build. Please note this part is not CARB approved and cannot be shipped to California.
