What is the main benefit of the Kooks GREEN catalytic converters?

The Kooks GREEN catalytic converters are 400-cell high-flow units. They are designed to be more efficient at reducing emissions than standard converters while minimizing exhaust flow restrictions, which can help improve engine performance.

What other parts are needed for installation?

This H-pipe requires Kooks headers with 2-1/2 inch collectors to be installed. You will also need to reuse your vehicle's OEM clamps for the connection to the factory muffler section, as only the H-pipe outlet clamps are included.

Can this H-pipe be used with forced induction setups?

Yes, the Kooks GREEN catalytic converters are suitable for use with forced induction applications like superchargers or turbochargers, offering improved exhaust flow for these performance setups.

Product Details

If you're looking to get more out of your 2005-2010 Ford Mustang GT's 4.6L 3V engine, this Kooks GREEN Catted H-Pipe is a solid choice. It's designed to connect to Kooks headers and work with your factory exhaust system, helping your engine breathe easier and potentially unlock more power.

This H-pipe is constructed from T304 stainless steel, which is known for its strength and resistance to corrosion, meaning it should hold up well over time. The system features Kooks' GREEN catalytic converters, which are high-flow 400-cell units designed to be effective while minimizing restrictions. This setup is specifically made to bolt up to Kooks headers that have 2-1/2 inch collectors, and it uses a ball and socket connection to the headers for a good seal. The outlet is 2-1/2 inches, designed to connect to your stock exhaust using the factory clamps, though new clamps for the H-pipe outlet to the factory muffler section are included.

Keep in mind that this H-pipe is not CARB approved and cannot be shipped to California. It's also important to note that this part requires Kooks headers to function correctly. If you're aiming for an improved exhaust note and better flow, this H-pipe is a well-built option for your Mustang GT.
