Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4551006. 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 2003-2006 Chevrolet Silverado 2500 HD, 2003-2006 GMC Sierra 2500 HD, 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.

Stainless Steel 3-in-1 Sponge/Brush Holder with soap dispenser for Kitchen
This is an ideal item to organize your sink areas. Perfect for kichens but also for bathroom use. I love the built in soap dispenser. The one I currently have doesn't have a dispenser. And the big liquid soap container is always falling over. Mine irack is bigger but this one is more organied. Easy to clean. stainless steel. Smaller foot print so it sits right near the faucet easily. 7.3"L x 5.3"W x 6.5"H And, it has drainage holes in the front rack to keep your sponges fresh by quickly drying. I was going to put this in one of our smaller kitchens in a guest house, but I may just snag it for my kitchen! Good value. Priced right.

Sticky wicket!!
This product arrived as described with one exception. There is a label on the front with a sheer plastic covering which mostly comes off, however the paper and adhesive remaining defy every solvent known to man!!! It has been soaked (twice) in Goo Gone, twice in rubbing alcohol, once in stainless steel cleaner and three times in Dawn power wash.....It remains.... I'd go after it with a razor blade, but I don't want to scratch the stainless.
