OEM Grade Direct-Fit Catalytic Converter

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-178. 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 specifically for the 2009-2015 Cadillac CTS and interchanges with OE part 22940825. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed Federal emissions requirements set forth by the EPA, complying with legal standards for OBDII Federally registered vehicles with California or Federal/EPA Emission systems.

Great Phone Holder
Style: Holder+Dash+Vent+Windshield
I bought the version with the suction cup mount and I’m very happy with it. It holds my phone securely in place and doesn’t move around while driving. It’s also very easy to place the phone in the holder and remove it when needed. The suction cup sticks well to the dashboard, and you can position it so the phone stays in a safe, easy-to-see spot while driving. Overall, a great and reliable phone mount. Highly recommend!

Best product and customer service around!!
One of the best car mounts I've ever bought! I love the mount’s powerful magnet, which ensures your phone stays locked in place even on bumpy roads, and the strong adhesive that sticks firmly to the back of the Tesla screen and holds it steadily. Plus, their customer service is off the charts. Very helpful and responsive.
