Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4551404. 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 specifically for the 2003-2004 Toyota Tundra. 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.

Great cable
With no other reviews I was a bit hesitant to buy this cable at first. I've seen so many other brands and sellers that sell cable that is half the gauge they claim. Or cable that is not totally copper and has tin or other poor metals in it. Especially at this low price I worried. I went ahead and bought some anyway though and figured I would chance it. For the amount of money I'd be saving it was worth it. If it wasn't as advertised I could just return it anyway. It arrived in a couple days. It is truly 1/0 AWG, and it is 100% copper. Strands packed dense but still flexible. Comes in a nice carry case. I crimped and soldered on some ends. Everything looks great and is working great. Would definitely recommend and would buy again.

Great wire.
Color: Black, Size: 15 feet
The flexibility is wonderful to work with. I used the red and black for a car audio application and it was a perfect choice for bending and snaking through the engine compartment and interior of the car. I have some just sitting on a bench and it still hasn't corroded and it's at least 3 years old. The insulation is very supple and has a nice feel to it and it carried current no problem of course.
