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.

Nice shirts! Fit perfectly!
Color: Dark Green, Size: Large
REALLY nice shirts! Bought dark green and black for my 23 year old son before he left for his six month cruise job to East Asia and they look to not wrinkle at all, plus they fit perfectly and look great! He's 5' 10" and about 170 lbs and wears a large. It fits a little loose, but he likes it that way. I would highly recommend these shirts!

Color is off, but still a nice shirt.
Color: Brown, Size: X-Large, Color: Brown, Size: X-Large
The shirt is great as far as quality. Material is very nice. Hubby wears an XL, and I bought the XL and it fit him perfectly. He is 5'11" and weighs 210lbs. The reason I gave a 4 star, and not a 5 star is because I ordered the brown color. When you look at the brown option on the color option, you will see from my pictures posted that I did not receive a brown shirt. What I received was more like a rust color or a copper color. I kept it because I actually liked it. But Amazon needs to do better with their color descriptions. If you're looking for a genuine brown color, this is not the shirt for you.
