Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 5481353. 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 2007-2008 Hummer H3, 2007 Chevrolet Colorado, 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.

Nice comfort and warm seat cover
Color: Pearl, Size: Front Seat Cushion-1 Pc
Used when traveled to Florida and back (3,000+ miles). Nice comfort and fit onto my Honda CRV seat good. It has straps and clips to hold it in place and rubber backing to keep it from moving around. In the winter it warms you up quickly, added bonus not expected. The quality is good, not problems with piling, or coming apart.

It’s great quality in terms of the fur, but the non-slip aspect lacks.
Color: Pearl, Size: Front Seat Cushions-2 Pcs
I wanted this not to provide extra cushion - although it does. I got this more to protect my seats in my sedan because they are tan in color and a suede-type material. So my jeans would bleed blue or black pants ect… would cause problems. It works perfectly for the purpose I wanted it for. I no longer damage my seats, and it does not appear that my pants colors bleed into the sheepskin either. Or at least it’s so minimal I have not noticed. I even spilled a bit of water by accident, and it came off very easily too so that’s a bonus. It’s lacking in the non-slip department. I understand the bottom is designed to be non-slip, and I do utilize the clips that attatched into the seat (the clips just slide out). Despite this is slips often. It’s not a deal breaker, but it was very disappointing. It’s frustrating to re-adjust. The gripping material underneath is not super textured like I thought. The clips not working as indented is also annoying. They don’t provide any gripping it just comes out no matter how hard I push inward. Also, the color I bought is slightly different from what I received. I know colors vary from photo to life, but it seemed like the color was just off a tad. It was supposed to be a lighter beige according to the photo, but it’s darker. Not a deal-breaker again, but something to consider. It was close enough for me. Overall still a good purchase, but depending on why you are buying these things may stand out to you.
