OEM Grade Direct-Fit Catalytic Converter

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-178. 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 2009-2015 Cadillac CTS and interchanges with OE part 22940825. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed Federal emissions requirements set forth by the EPA, complying with legal standards for OBDII Federally registered vehicles with California or Federal/EPA Emission systems.

Comfortable, durable, and cute — perfect everyday shoes for kids
Size: 2 Big Kid, Color: Pink Milk
I purchased these Crocs Unisex Classic Clogs in Pink Milk for my daughter and they were a perfect choice. The color was a beautiful soft pink and exactly as pictured. They were incredibly easy for her to put on and take off by herself, which was a huge plus. The lightweight material and comfortable footbed made them her go-to shoes for both indoor and outdoor play. They were durable, easy to clean, and the sizing was accurate. We have bought several pairs of Crocs over the years and these maintained the same high quality. I was very happy with this purchase and would definitely buy them again.

Toddler boy loves them!!
Size: 9 Toddler, Color: Purple, Size: 9 Toddler, Color: Purple
My toddler boy absolutely loves the color purple and he squealed with delight when he got these from the Easter bunny. They are true to size and he says they are very comfortable to wear. Easy for him to slip on by himself. He decorated them with sea animals and they are his favorite shoes to wear every day! They’ve held up great over the last month so far. Photo included of his favorite way to wear them (on the wrong feet lol). Will definitely purchase another purple pair when these get too small.

Perfect pristine condition
Size: 12 Little Kid, Color: Mint Tint
Bought this in a neutral light green for my grandson's extra shoes for his weekend visits. Got a size larger than what he wears now, so he has to wear them "four-wheel drive" (w/ straps). Honestly, I just got the cheapest in this size, because he's at that big growth time, and they'll end up in the charity box before he wears them out. Crocs are of a good quality, and seem ideal for little growing feet. They clean up easily in the dishwasher or with a little scrub in the sink. They're easily replaced, and if they get swept up by the wind and deposited into a lake, they will float and may be easily fetched up in a net and returned to the owner (true story). Crocs dry fast, and keep feet from lingering odors without additives.

They Shouldn’t Work But Here We Are
Size: 13 Little Kid, Color: Mystic Purple
Let’s address the elephant in the room: Crocs look like a rubber cheese grater had a baby with a sandal. And yet somehow these things are a parenting cheat code. The comfort is unreal (10/10). Kids slip them on and suddenly they’re walking on clouds, bouncing around like tiny caffeinated marshmallows. Cleaning them is almost suspiciously easy (10/10) mud, juice, questionable playground goo just rinse and move on like nothing ever happened. The ventilation holes (9/10) actually do their job, keeping little feet from becoming sweaty disasters, though they also double as convenient entry points for sand, pebbles, and whatever treasures your kid decides to collect. Style wise (7/10), look… no one is winning fashion awards here, but kids love them and confidence is half the battle. The heel strap (9/10) deserves a medal flip it back and suddenly your child enters “sport mode” like a video game character with boosted speed stats. The color options (10/10) are wild enough to satisfy even the most chaotic tiny human, from neon explosions to surprisingly normal shades. They’re ridiculously lightweight (10/10), which is great until your kid forgets they’re wearing them and tries to wear them to bed. Durability (9/10) is solid they can handle running, jumping, puddle stomping, and general kid nonsense without falling apart. And the independence factor (10/10) Huge. No laces, no struggle, no dramatic “I can’t do it!” moments just slip on and go. Crocs as a brand (9/10) clearly know their lane comfort over cool, and honestly, it works. Final Score: 9.2/10 They may not be pretty, but they’re practical, indestructible, and weirdly lovable like the chicken nuggets of footwear
