Kooks 14+ GM 1500 Series Truck 5.3L 3in x OEM Out GREEN Cat SS Y Pipe Kooks HDR Req

If you're looking to get more out of your 2014-2018 GM 1500 Series truck or 2015-2020 SUV with a 5.3L engine, this 3-inch stainless steel Y-pipe from Kooks Headers is a solid option. It's designed to connect to Kooks Long Tube Headers and then transition to your factory exhaust system, helping to improve exhaust flow and sound. This Y-pipe features a high-flow GREEN catalytic converter, which is a 400-cell unit designed to help reduce emissions while still allowing for better exhaust gas movement than a stock converter.

Crafted from T304 aircraft-quality stainless steel, this Y-pipe is built to last. Kooks has been in the performance exhaust business for over 50 years, and they build their products in the USA. This Y-pipe uses a ball and socket connection to mate with the headers, which helps ensure a good seal. The outlet is designed to connect to your OEM exhaust system, and it reuses your factory hardware for that connection. It includes clamps to help secure the connections.

Keep in mind that this Y-pipe is specifically designed to be used with Kooks Long Tube Headers. It's also important to note that this part is not CARB approved and cannot be shipped to California. If you're aiming for improved exhaust flow and a more aggressive sound on your GM truck or SUV, this Y-pipe is a well-built component to consider.
