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.

Stays in place no white cast. THE BEST!
Size: 1.7 Fl Oz (Pack of 1)
BEST facial sunscreen I have ever used. I also use Color Science tinted sunscreen when I’m not wearing any “makeup” . I was looking for a sunscreen to use under my regular makeup. I’ve tried several products that were highly recommended . This sunscreen actually makes my high-end makeup look smoother, softer and even looks to blur the wrinkles more than just the makeup. My makeup stays put it doesn’t pill, shred or melt off. I also wear it without makeup when exercising outdoors, so of course I’m going to sweat. It doesn’t burn my eyes if I sweat and actually stays in place. I also put it on my neck and Décolletage and it does not melt off. I know it’s pricey, but it’s worth it. I highly recommend this product. Check out the other Color Science tinted sunscreen It’s amazing too.

Truly no cast
Size: 1.7 Fl Oz (Pack of 1)
Goes on very smooth and there is truly no white cast. No weird smells, no stringing eyes etc. This is a great product, just wish the price point per oz was better

No White Cast
Size: 1.7 Fl Oz (Pack of 1)
No white cast. I use the 2 finger method and have medium-deep skin tone. I have slightly oily skin and it does not leave my skin with a greasy, shiny or sticky either. I will definitely buy this again.

Best sunscreen in the market
Size: 1.7 Fl Oz (Pack of 1)
Very good quality sunscreen. Doesn't cause break outs. Good for sensitive skin. Invisible and blends into skin well but does leave a slight white dew to your face. This is okay with me though
