Kooks 2007+ Jeep Wrangler JK w/LS Swap 3in Catted SS Y-Pipe Kooks Headers Required

If you're putting an LS engine into your 2007-2018 Jeep Wrangler JK 4-door, this 3-inch stainless steel catted Y-pipe from Kooks Headers is a key piece of the exhaust system. It's specifically designed to work with LS engine swaps, particularly when using the RPM Extreme or Motech LS Swap Kits, and it must be used in conjunction with Kooks brand headers. This Y-pipe is constructed from T304 aircraft quality stainless steel, which is known for its strength and resistance to corrosion, making it a solid choice for off-road vehicles that see varied conditions.

This Y-pipe includes catalytic converters to help reduce emissions, though it is not CARB approved and cannot be shipped to California. The T304 stainless steel construction means it's well-built to handle the demands of a swapped engine and the rigors of off-road use. Kooks has been in the performance exhaust business for over 50 years, and their products are dyno and race tested to ensure they are designed for maximum power. All Kooks products are handcrafted in the USA.

When planning your LS swap exhaust, remember that this Y-pipe is designed to connect to Kooks headers. Ensure you have the correct Kooks headers for your specific LS swap application to ensure a proper fit and optimal performance. This part is backed by a limited lifetime warranty to the original purchaser.
