Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-169. 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 2009-2016 BMW Z4 and interchanges with OE part 18 30 7 647 040. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Little big
Size: 20, Color: Rinse Wash
They run just a tiny bit big. The length is more ankle length instead of capri length as shown. However, I liked the wash and the length doesn't bother me. Perfect match to the essentials jacket.

good stretch
Size: 10 Long, Color: Dark Wash
Honestly, these are one of those surprisingly good basics—especially for the price. The biggest standout is the stretch. They’re really comfortable and move with you, so they don’t have that stiff “jeans” feeling. They hug your body in a flattering way without feeling too tight or restrictive, which makes them easy to wear all day. The mid-rise fit is also a sweet spot—not too low, not too high—so they’re super versatile with different tops. What I liked: Very stretchy and comfortable (almost feels like jeggings, but still looks like denim) Flattering skinny fit through the legs Easy everyday jeans—work, errands, going out Great value for the price What to know: Material is on the thinner side (more comfort than “structured denim”) They can lose shape slightly after a full day of wear Not the most durable long-term compared to higher-end denim Final thoughts: These are perfect if you want cute, comfortable, affordable jeans you can throw on with anything. Not premium denim, but for everyday wear—they definitely get the job done and are worth having in your rotation.
