Kooks 09-10 Ford F-150/ Ford Raptor 5.4L 3V 2 1/2in x 2 1/2in OEM Cat Y Pipe Kooks HDR Req

Starting with 16-gauge 304 stainless steel construction, this Kooks catted Y-pipe is built to handle the demands of your 2008-2014 Ford Expedition or 2009-2014 Lincoln Navigator. Designed to connect directly to your vehicle's OEM exhaust system, it features a 2-1/2 inch outlet for a smooth transition. This Y-pipe is specifically engineered to work with Kooks Headers, utilizing a 2-bolt flange connection to ensure a secure and leak-free fit with their performance header systems. The integrated high-flow catalytic converters are a 400-cell design, intended for naturally aspirated applications and are not suitable for forced induction setups.

This Y-pipe is a key component for improving exhaust flow when paired with Kooks headers. The 2-1/2 inch diameter piping helps maintain exhaust velocity while allowing for increased volume, contributing to improved engine performance. It's important to note that this system requires Kooks headers with 2-1/2 inch collectors to ensure proper fitment and function. The included Y-pipe clamp ensures a solid connection to your existing exhaust system, making installation more straightforward.

Please be aware that this Y-pipe is not CARB approved and cannot be shipped to California. It is designed for performance enhancement in naturally aspirated engines and should not be used in forced induction applications. Ensure you have the correct Kooks headers installed to properly integrate this Y-pipe into your exhaust system.
