Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 458011. 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 Chevrolet S10 and 2003 GMC Sonoma. 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.

Great Product at an Amazing Price!
Size: 41.3 x 27.5, Color: Coffee
I bought 2 of these crate liners to use as beds when I board my dogs and I couldn't be more thrilled with them! These beds are much sturdier than I expected for the price, very thick and comfy and both of my dogs love theirs! Even my 130lb Fila x Rottie is supported by this bed, and he's cushioned from the cement floors at the boarding facility enough I don't worry about any pressure sores on him. I'll definitely be buying extras of these beds to have on hand.

Price is right. Soft and squishy night for my chonk of a dog. She’s a big girl, weighs 140lbs. Fits her size nice. Treat your furbaby to a comfortable bed.

Nice doggy beds for the fur-babies!
Size: 41.3 x 27.5, Color: Grey, Size: 41.3 x 27.5, Color: Grey
This is nice, soft and fluffy, the fur-babies seem to love it. It does shed a lot so far. Females have been fluffing it themselves (dig/scratching) and has seem to be holding up well. These arrived vacuumed sealed. I was a little worried there would be a strong scent but was pleasantly surprised they aired out very well. I think these will be a nice addition to my fur-babies kennel. I only wished I would have sized up one more for a better fit for my kennel that’s interiorly 53x45. I think these 47x35 instead of 41x27 would have fit better. Other than the shedding and (my fault) the sizing I think they are great. I think a removable cover would have been nice but these are priced right I could always just buy again if need be.

Very happy!
Size: 41.3 x 27.5, Color: Grey
Buy this bed! My fur son is a destroyer. Toys, balls, beds. Nothing is safe. Knock on wood, this bed has held up to his destructive behavior. And it’s so fluffy! It is big enough that I don’t think it’s going to fit in my washer. I will have to take it to the laundry mat to wash it eventually. At that point I will update on true durability. But all in all I find it to be a quality purchase.
