Overview:

Keep the check engine light off with MagnaFlow HM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 55321. 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 1997-2002 Ford E-250 Econoline, 2000-2004 Ford E-350 Super Duty, 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.

Soft, comfortable fitting jeans
Size: 30W x 30L, Color: Black Rinse
Good quality and a great slim fit, but a bit expensive for a blend. Since they aren’t 100% cotton, they have a slight stretch that makes them more comfortable and softer than standard jeans. I’m happy with the look and feel, but I’ll have to see how they hold up over time.

Very nice and would highly recommend!
Size: 32W x 30L, Color: Medium Grey
The fit is exactly what I was looking for, slim without being too tight, and it fits true to size, so I get that modern look but still feel comfortable sitting or walking around all day. The denim feels soft yet sturdy, which makes me confident it’ll hold up well over time. I also love the classic 5-pocket design. It’s functional and keeps my essentials handy without adding bulk. The color holds up after a few washes, and there’s minimal fading so far, which is a big plus for me. Pairing these pants with a casual tee or a button-down is effortless, they easily transition from work to weekend vibes. For the price and quality, I feel like these are a solid addition to my wardrobe. Definitely recommend if you’re looking for a slim, comfortable, and versatile pair of jeans.

Love these jeans
Size: 34W x 30L, Color: Black Rinse, Size: 34W x 30L, Color: Black Rinse
Nice jeans. THe fit is great, the material is kind of stretchy, and the black color is true black not a faded look. Hard for me to find a good pair of jeans but these I love.

They feel like cardboard
Size: 36W x 29L, Color: Medium Grey
I kept these hoping to replace a denizen slim 216 that I can’t find anymore. These are not as a soft and rather quite stiff, maybe due to the recycled content. They might do for the occasional trip out of the house but I’m not impressed and glad I didn’t pay full price.

All Day Comfort
Size: 34W x 32L, Color: Medium Grey
If you like the trim look of slim-cut jeans, you will love these. The silhouette is near perfect without veering into skinny jeans territory and the extra length make mine perfect with boots. The denim is good quality and the stretch fabric retains its shape, resisting the baggy look after multiple days of wear. The grey color is just right without the unnatural whiskers and wear-lines added by other brands. I love these jeans and look forward to many years of uses.
