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.

VELCRO Ties Are the Standard to Rely On
Size: 150Pk - 8" x 1/2", Style: Cord Wrap Cable Ties, Color: Black and Gray
I am a big fan of VELCRO brand products because of their quality and utility. I have used their rolls of Velcro hook and loop tape as well as their little patches, and I became a brand loyalist. Yes, there are many other manufacturers, but these are certainly as good as it gets. This product is your very basic, very thin, and very copious supply (for my neighbors in Rio Linda - that means plenty of them). You get two big spools of these little eight (8) inch ties that are adhesive throughout their length - that means you can tie the smallest cables to anything almost up to their full length. If you need a longer wrap - use more than one and just extend the length by piggy backing them. The real advantage of this bulk package is that you are not tempted to save some for later - you have enough to use as many as you like and can happily go tie crazy on all your cords! It's VELCRO party time. We live in an electronic age, and I have a lot of more pricey hook-and-loop specialty ties, and I try to keep a few back as spares. Forget that - with these little ties, I can actually use them and do what I need to get those tangled cords in shape. O.K. maybe I am a geek, but I cook my chicken - dead already, and I believe in independent segregated wiring and not tripping over things or spending time untangling messes when I need to move gear. These big rolls will make your life easier - I use them to attach notes to little jars or vials - to tie two gloves together when I am not wearing them - and other uses even cutting them into smaller pieces. That's one of the advantages of these bulk spools - lots of supply. Yes, the individual ties are dinky thin little things, but they hold very well (why you buy genuine VELCRO) and you don't feel stupid using them up on anything you feel like. They are expendable, and that adds to their ultimate utility. Darned useful product. Buy it - use it; enjoy.

Computers, electronics cabling? You NEED these!
Size: 100Pk - 6” x ½”, Style: Cord Wrap Cable Ties, Color: Black
If you do any cabling, be it TV or computer or anything else, these ARE worth there weight in gold. Seriously! They'll keep your cable runs, extension cords, etc in a nice neat easy to work with bundle that you can have out of the way. Adhesion is very good also which is also important. Just the right size for most applications and if you need something large they make them to fit your needs. Cable management has always been a pet peeve of mine and makes a difference that not only shows but makes future work and maintenance much easier. Whenever I see a rat's nest cluster of wires I always know it means shoddy workmanship!

Very Effective, but Not the Instructions
Size: 150Pk - 8" x 1/2", Style: Cord Wrap Cable Ties, Color: Black and Gray
These work very well, but when you remove them from the box, you see two donuts, one grey, one black, of 75 tightly wrapped cable ties each. So far, so good. First deficiency: The "how to use" pictures---three of them---are tiny light line drawings in 7/16" x 7/16" boxes. If you don't have a 400-power microscope, maybe a magnifying glass will do. Maybe Velcro---a "name" brand that should know better---thinks that the use of these devices is obvious. Well, "obvious" is obvious only when it's obvious, and that can vary from person to person. They should assume nothing. Second deficiency: Before trying (and, one hopes, succeeding) at using these ties, one must determine exactly now to remove the first tie from the outside of either donut. Obvious? No, not really, because, as it turned out, it requires some effort to remove the first one---the placement and circumstances of which do not at all (not on my set of these, anyway) suggest in any concrete way which one should be taken first. No one wants to tear up a couple of ties just to figure out how not to tear up ties by removing them incorrectly or out of order. The punishment here is four stars that could have been five.
