Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 444312. 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. Designed to fit the 2003-2005 Toyota Corolla, 2003-2004 Toyota Matrix, and more, this direct-fit catalytic converter also interchanges with OE parts 17410-22500, 17410-0D150, among others. 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.

Great for Tall Guys
I got this for my husband, he has a pullover that he has worn for years and it needed replacing. Finding one like this that was lightweight and loose fit was a big challenge. He loves the quality and fabric and its not hot but still helps when their is a breeze or chill. I liked that the color and pattern are versatile for all seasons. He is 6'5 and it actually fits his torso! Just get it!

It’s a hit!
Color: Brown Grey Camo, Size: Large
I picked on of these up after seeing it online. I have multiple Maelreg items and all are great quality. They are my go to golf and casual clothing brand. Super comfortable, soft, light weight, and perfect fit. Olive on the east coast and this color is all the rage in the area. These are some of the best value 1/4 zips out there.
