Show original supplier description
The ZZPerformance ZZ-GPDP-2.5-C is a direct-fit catalytic converter engineered to enhance the exhaust system of select GM vehicles. With a 2.5-inch diameter, it is designed to facilitate improved exhaust flow compared to stock components. This downpipe serves as a direct replacement for the factory catalytic converter, allowing for a straightforward bolt-on installation without the need for modifications on compatible applications. This catalytic converter is specifically designed for models equipped with the 3800 engine. While the primary listing title mentions Monte Carlo, Impala, and Regal, it's crucial to verify fitment with the "Add your vehicle" tool to ensure compatibility with your specific year, make, and model. The OE/OEM part numbers cross-referenced include 10343189 and 24205, further aiding in identification.
