Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4551419. 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 2003-2005 Chevrolet Silverado 1500, 2003-2005 Chevrolet Tahoe, 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. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to be certified by CARB for legal use in CA/CARB restricted states for the listed vehicles.

Easy to assemble. Works well. Looks nice.
Color: Light Grey, Color: Light Grey
Works for what we need. Easy to put together. Diagram provided was clear. One of the lil screws didn't fit perfectly, but it works well enough. Came with all the lil tools you need to assemble. Product frame is sturdy and hardware (seems heavy duty enough, metal and not plastic) all fits together very nicely. Would buy again if i need another one.

Great value!
Color: Light Grey
I purchased this for a divider in the sanctuary of our church. Making a private prayer corner.. It is way better than expected. Follow direction . When you make the "M" shape put close together. I had the letter tops to far apart and it complicated things. Otherwise it was awesome. Would definitely buy another one if needed

NO DELIVERY DO THEY EVEN HAVE THE PRODUCT TO SELL??
Size: 5 Panels, Color: Grey
There is a problem with the Seller delivering on the products sold. Or someone is selling on behalf of the seller and not being able to deliver. Purchased 3-part panels used no problem, and are nice, but we also needed the 5-panel divider. which has been promised twice for delivery and NOT delivered without explanation. We'll have to send the other back as we'll need something that match.

5-Panel Office Privacy Divider
Size: 5 Panels, Color: Grey
The Natwind 5-panel partition is a practical solution for creating privacy or dividing space in offices, studios, or shared rooms. Measuring 122.8" x 71", it provides generous coverage, while the foldable design makes it easy to set up, move, or store. The freestanding panels are sturdy and offer some acoustic dampening to reduce noise. A versatile and portable divider that works well for temporary or flexible room layouts. Solid quality and sturdy.
