Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-408. 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 2016-2017 Cadillac ATS, 2016-2017 Chevrolet Camaro, and more, this direct-fit catalytic converter also interchanges with OE part 12656953. Hardware is included to eliminate the hassle of working with corroded factory parts.

read the fine print
Size: X-Large, Color: Black
I really need to learn to read the small print. That pocket line on the chest turned out to be a fake pocket and the actual; zipper on the sleeve is also a fake pocket; my bad but in my defense I'd never dreamed that anyone would put either on a shirt. Also my search term was men's "cotton shirt w/ pocket shirt" and it brought up this polyester wonder. But at least it fits well and seems well made.

High‑style look that feels way more expensive than it is.
Size: X-Large, Color: Orange
Okay, let’s talk about this shirt because I was not expecting to love it as much as I do. The Men’s Long Sleeve Polo Shirt with the quarter‑zip is giving premium designer energy without the designer price tag. From the moment I put it on, the fit was chef’s kiss—slim, clean, and athletic without feeling tight. The fabric has that smooth, high‑end feel you usually only get from brands that make your wallet cry. But here? You’re getting elevated style at a totally reasonable price.
