Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4551644. 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 2007-2010 Chevrolet Silverado 2500 HD, 2007-2010 GMC Sierra 2500 HD, 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 personal item for travel
Color: Black
I recently used this bag on my cruise. It fits perfectly under the seat for a personal item. The quality is nice and the bag is spacious to back many items. The only thing I didn’t like is that I kept having to adjust the straps due to them coming loose.

Hidden Gem!
Color: Desert
Huge and suitcase like on the inside. The zipper is the same color as the backpack and looks luxurious. Very soft and cushy even with heavy stuff in it. Like a laptop. Which there is a specific place for it that is cushioned. But my favorite by far is the clear pockets on the inside. I like that you can see what your getting out of your bag and where to find what. Also the outside pockets are really useful! And kinda incognito which is great for if you want to put valuables there. You can use this for travel, school and work. It's very versatile. Very good for organization. Comgortable and easygoing. Quality is 5/5.

Lovely Bag
Absolutely love this bag. The strap is a little tricky to adjust but once you do it’s are perfect. The whole thing came in a duster bag with material to protect the interior and integrity of the shape. Great product.
