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.

Quality!

Stylish and most importantly they are comfortable right out of the box, no breaking in required. This is my second pair, I now own both the black and brown colors to compliment almost any outfit. Worth the price!

Absolutely comfortable.
Size: 9, Color: Brown Multi
I am always on the lookout for a professional, but very comfortable shoe (education field with a lot of walking). These Florsheims fit the bill and make me wonder why I never bought these before. Something about them just didn't "look" comfortable to me but man was I wrong. These are easily among my most comfortable work shoes with the bonus of also looking more professional. I will say they have some heft to them, so if that's a problem for you these may not be right for you. As for me, they are right as rain. I purchased the black and brown ones (with white souls) and they are at the top of my rotation now. I look forward to trying some more from Thai company.
