Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51737. 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 2001-2003 Mazda Protege and 2002-2003 Mazda Protege5, this direct-fit catalytic converter also interchanges with OE parts FSAG-20-600A, FSAH-20-600A, among others. Hardware is included to eliminate the hassle of working with corroded factory parts.

Great Denim jacket!
Size: XX-Large, Color: Tinted Light Wash
I purchased a 2xl for my husband and it's a great quality and price. He really loves it. It's a good stretch and he's able to place a hoodie or a thicker shirt and still be comfortable if need be. Will be purchasing him another color of this jeans jacket.

Good Value Denim Jacket With True to Size Fit
Size: X-Large, Color: Black
Great denim jacket for the price. It feels durable and well made, though the quality is not quite on par with higher end name brands, which is to be expected at this price point. The fit is true to size and matches expectations. It is comfortable out of the box and, like most denim, should become even more comfortable as it breaks in over time. The arm length runs slightly long, but if you usually find sleeves long on jackets, this one will fit similarly.

Great base to add patches to
Size: X-Large, Color: Black
I've bought this jacket twice now (lost the first one...). Great base for my DIY patch jackets. I buy an XL even though it's a size too large for me. It's a standard denim jacket, not much to write home about. Good pocket size, and I appreciate the functional chest pockets.

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.
