The 3" MagnaFlow 4451309 California OBDII universal catalytic converter is the best replacement for your stock cat on your OBDII vehicle. It complies with CARB requirements, and you can install it in your truck or car if you live in the state. The converter helps to reduce poisonous emissions while also improving the performance of your exhaust and engine.
The converter features a monolithic honeycomb design for the catalyst. It increases the exhaust flow surface area for maximum conversion even with high exhaust volumes.
The cat also has a ribbed heat shield that provides a rigid wall for heat protection. It creates a stable structure to contain the hottest exhaust fumes. You won't have to keep an eye on the Check Engine light.
The MagnaFlow 4451309 California OBDII universal catalytic converter has a firmly welded seam to create a strong bond between the catalyst and the wall. It ensures that the catalyst stays intact and does not loosen and shift inside the converter.
It is designed to fit your vehicle's OEM exhaust system regardless of its make or model. It may fit perfectly or require a little modification depending on your vehicle model.
The converter is made with premium-grade stainless steel that won't rust, oxidize or corrode. It stays strong for years and takes all the heat to maintain its hold.
The manufacturer provides a 5-year or 50,000-mile limited warranty for every purchase of the MagnaFlow 4451309 California OBDII universal catalytic converter. This is a guarantee of quality and performance beyond the ordinary. If you need help with your warranty or you would like further information, feel free to reach out to PartCatalog.
The cat is proudly made in the USA with a local labor force, raw materials, and technology. Your purchase not only helps to support local businesses but also creates jobs for thousands of Americans every year.
