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 value for price. Cute, lightweight. Could be used anywhere.
Size: 3 Panel, Color: White
Nice, lightweight. Good value for price. It's exactly what I needed for my hallway to keep my cats separate from each other. I used two zip ties to eyescrews in door trim and it opens up perfect to wall. Warm air gets thru and cats can see out/in. But can't get under or over. It's perfect for my use!!!!

Great seller and really nice items!
Size: 6 Panel, Color: White
These room dividers are really lovely. They are great quality and just perfect for providing privacy in a sunroom while still allowing light in to keep the room sunny. I highly recommend.

Nice divider!
Size: 4 Panel, Color: White
I use this as a "barrier" to keep my cat out of the guest room. I don't have to close the door anymore because the divider allows light and air through. Adds a nice touch to the decor, as well. Very lightweight and serves its purpose.

Good Room Divider
Size: 4 Panel, Color: White
This room divider worked great to mask my "utility area" in my living room because I'm low on storage space. It's functional and pleasing to the eye, but the quality could be better as there were pieces of debris on the unit and fraying strings. It also can tip over if not positioned just right. I do like the versatility of it though because even though it's a four panel I can fold in one of the panels and use the other three. Overall I like it, the price could be lower based on the quality but its good.
