Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 5491966. 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. Avoid potential exhaust leaks by using the included gaskets to get a proper seal. 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.

Color is awesome but material isn’t.
Size: 34W x 32L, Color: Blue, Size: 34W x 32L, Color: Blue
The color is pretty much as advertised. I wear a 33 so I order up a size and they were both too long and too big. Instead of returning them I washed them and put them in the dryer. The length after washing turned out perfect but the waist is still a little too big. It should also be noted that the quality of the material isn’t the best. After washing them this is how the pockets will look. You have to iron them each time to get them flat again. I would buy again because of the variety of colors but only at a cheaper price.

The jeans are a nice color, and length… they run SMALL… I wear a 33-34 and bought a 36. They were skin tight but breathable material… I sent them back to order a 38

I’m happy with the jeans
Size: 40, Color: Pink
I am very satisfied with this purchase. A lot of compliments too. They fit well, stretch to the material but the skinny fit look. The quality so far is great.
