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.

Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
Love this product. May not be compatible for someone who doesn't like smell of coffee that does not detract from the product. it's really good for hair.

So far nothing amazing
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
So I’ve been using for a couple of weeks now and I haven’t noticed any difference. I am going to continue on. I don’t know if it takes time for it to actually show some results. I will say two things about it. It comes solid for 12 my jar cracked and broken And it’s non-returnable so I just have to deal with it so that’s unfortunate after paying $20 second of all it is a solid mass so you have to put it in your hands and kind of warm it up for it to become any sort of an oil and I wouldn’t even consider it an oil at that it’s more of like a cream once you warm it up in your hands, but it doesn’t make your hair greasy. I use a small amount I would think that the jar would last a long time given that you don’t need a lot to get through to your scalp unfortunately, with my jar being cracked, I don’t know how that’s gonna affect the longevity of the product And it does have a smell think of burnt coffee beans that will dissipate after about an hour to an hour and a half after putting it on, but if you’re not putting it on, I’m just going to bed. It might be become an issue. I’m gonna wait it out. I hope I do see results from doing this but again so far nothing.

Wonderful product
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
I used this on a bald spot I had and it worked extremely well. Consistency is key though it needs to be used every day

It works and I love it!
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
I love this product.. been using it for a few months now. My hair is more manageable and my thinning crown looks and feels fuller. The smoky smell, am not bothered because it disappears after a few minutes. I use it twice a week, massage very little amount on scalp and hair, then the next day wash it off with shampoo. I used to need to dye my gray every 3 to 4 months when some appear. Now, it's been 4 months since my last visit to the salon. I noticed my hair has darken a bit. I can delay my salon visit for another month unless I need a haircut!! Yehey!

Good moisturizer. Rich scent.
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
Raw Batana Oil provides goods moisturizing to hair and scalp and best applied with a little heat or steam. Pomade goes on easily once heated and does not feel heavy, greasy, or oily. Its rich fragrance eases on the nose after a short while. Difficult to say whether it is actually useful or whether it encourages hair growth. Leaves hair soft and easy to style.
