Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51277. 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 2003-2005 Mazda 6 and interchanges with OE parts AJ57-20-50XC and AJB4-20-50XB. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Good sunscreen
I really like the little bit of glow it gives my face. I’ve used it several times while on the water and it has worked well. I’ve not had any skin irritations.

Finish looks great. The light tint makes for a more even distribution. The smell is pleasant. SPF will help protect the face from the sun. I would purchase this again.

Replaced 3 products
This is a very good product. Everyday I use CeraVe lightweight 30 or 50 spf and mix Drunk Elephant D-Bronzi and B-Goldi drops for a tint and shimmer. This is the only “makeup” I wear as I don’t like heavy makeup and prefer just a subtle glow with a daily sunscreen. This product effectively replaces all of those products for me. I put this on to try yesterday afternoon and my husband immediately said “Did you do something different? You look good.” It’s is a little more runny than I expected but applies thinly (as I prefer) and provides just enough tint to cover some of my redness. The glow is beautiful. Love the packaging, the pump is very easy to manage and keep clean. Too soon to know if it will cause breakouts or how well it holds up in the sun (although my other experiences with SunBum have been that it works well). I will update my review if I have breakouts. Buy this! Edited to add: a dermatologist complimented my skin due to this product “your skin looks great, you’re glowing!” I have not had breakouts from using this product. I still use everyday with a little cream blush and mascara and call it good. I stock up when this goes on sale but even when not on sale it is a great price. Still not 100% sure about it’s effectiveness at sun protection although I’m pretty sure it’s better than nothing. Wish this exact product was available in 50 spf. Still a fave!

A tinted sunscreen.
It was really nice. However, it has a strong tint to it and feels like Makeup with sunscreen. Nice, but uninexpected.
