Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-989. With features including free-flowing mandrel-bent tubing and highly corrosion resistant, stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed to fit the 2002-2006 Chevrolet Silverado 2500 HD, 2002-2006 GMC Sierra 2500 HD, and additional vehicles. Avoid potential exhaust leaks by using the included gaskets to get a proper seal.

Last about a year ishhh
Size: Single Slat, Color: Glossy Black&M-Color
Plastic mold isn’t as straight as it should be, the clips don’t line up like oem. Product is wiggly. Had on car for over half a year. Hasn’t faded. Just wish the fitment was better. Update: the grill lasted about 1 1/2 years, it began to fade, and I had a slat crack, no evidence of impact. I ended up buying a better made product and replaced this grill.

Fits a 2001 330!
Size: Single Slat, Color: Black, Size: Single Slat, Color: Black
The grill in my old 2001 330 broke off and I was really happy to find a nice looking replacement at an inexpensive cost. The black looks really sleek on it and has breathed some new life into it. Next up is to replace the emblem.
