Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51578. 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 2009-2013 Chevrolet Silverado 1500, 2009-2013 GMC Sierra 1500, and additional vehicles. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Excellent Air filter - Easy installation.
Style: BE-743 1-Pack
Excellent AC and Heater Cabinet odor defense air filter. I noticed immediately the smell coming out of the vents was fresher and the musty smell that was coming from the vents was crisper and cleaner. Very easy installation that you can do yourself and don’t need to pay a shop to do. The price is one of the best online and coms in quickly. It’s very sturdy, filter quality is excellent and it definitely improves the air quality and flow in your car. Fits perfectly like any OEM filter, this is a great buy for the price of an installation that will take you Les then 10 minutes to do yourself.
