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.

My Heels Were in Bad Shape. Like… Really Bad
Color: Gray
These moisturizing heel socks with the gel cushions were honestly a small miracle for me. After recovering from cancer treatments, my skin became extremely dry everywhere, but my heels were the worst. They cracked so deeply they looked like fissures and were even bleeding. I tried lotions and bandages repeatedly with very little progress. A friend suggested I treat my heel like it might have a fungal component, so I applied Lotrimin cream, put these heel socks on, and hoped for the best. Within three days, my heels were fully healed. I completed a 7-day routine, and my feet have never been softer. The silicone gel cushion is comfortable, soothing, and stays in place. I loved it so much that I still treat myself about once a week, even though I really don’t need to anymore. They are also washable. I hand-washed mine in the sink and let them air dry, and they came out looking brand new. If your heels are cracked, painful, or need serious care, I highly recommend these.

Ehh. Not for me.
Color: Gray
Foot slides when walking in them. The fit was tighter than lead to believe. It did hold the moisture in but the silicone patch is small

Flawless Finish & Fantastic Value
These blenders are a total game-changer. The quality is fantastic, they are incredibly soft, bouncy, and provide a seamless, smooth finish for my foundation. I was also impressed by how well they handle powder for setting. Getting a 6-pack is an unbeatable value for the quantity. I am officially a fan and will definitely be purchasing these again!

best makeup sponges on the market....even better than the $20 ones
best makeup sponges on the market....even better than the $20 ones. super soft, even coverage, doesn't absorb too much product & extremely affordable for a multi-pack so you can start throwing away your sponges when they go bad instead of hanging onto them for concerning amounts of time
