HKS MTL CAT CZ4A 4B11

HKS is well-known for making performance parts that help engines breathe better and make more power. This direct-fit catalytic converter is built for the CZ4A chassis with the 4B11 engine, designed to replace the factory unit while improving exhaust flow. It's a solid option if you're looking to upgrade your exhaust system and want a part from a brand with a strong racing heritage.

This catalytic converter uses a high-flow metal substrate core, which is more durable and efficient than traditional ceramic cores, especially under demanding conditions. The stainless steel construction means it's built to resist corrosion and withstand the heat and vibration of daily driving. Because it's a direct-fit design, it bolts up to your existing exhaust system without needing any cutting or welding, making installation straightforward for a qualified technician. While it's designed for improved exhaust flow, it's important to note that this part is not CARB approved and cannot be shipped to California.
