Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4451218. 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 Hummer H2. 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 California Air Resource Board requirements, and has undergone additional testing to be certified by CARB for legal use in CA/CARB restricted states for the listed vehicles.

Love this Brand!
Bought a lamp post a few years back by this brand and absolutely love it. No need to run electric wires and the light looks no different. Bright all night long with a regular looking light bulb. Looked up this brand again to purchase some lawn stakes. Has the same brightness as a regular light bulb and will last much longer than traditional solar lawn stakes. Very happy with the purchase!

Item is plastic. Didn't unwrap because I was looking for glass solar pathway lights.
Size: 2 Pack
I didn't realize these were plastic. I wanted glass. The description said plastic but I didn't read that part of the description. I did not try them out to see how the light was so I can leave a review about that.

Bright
Very pleased with the light output from this solar light. Really shines a very large patch. I’v placed it in a area that needed some extra light so my security cameras can see a bit better overnight. This light did great. Anything in its area is easily identifiable. It went together fast and with full sunlight lasts till almost dawn. I’ll be getting a second so I have a matching pair. Four Stars ⭐️⭐️⭐️⭐️!!!

Love these solar lights
Why I chose to buy these expensive version of the solar lights: (1) 11 hours (hi setting light 80 lumen) to 18 hours (lo setting light 10 lumen) once fully charged by the solar. (2) The light emitted by the light bulbs are bright, and stay bright from dusk to dawn (3) Large battery capacity compared to competitors - 3.2 volts. (4) Bright bright bright - look like a real electricity powered light bulbs. (5) The morph solar panel is big, so it's able to absorb more solar power from every angles.

Quality all the way around
Size: 2 Pack
Build quality is excellent with both plastic an metal parts. Can't say how long they will last, but my Gamma Sonic solar pole light is still going after 5-6 years. I also have some Gamma Sonic solar spot lights still working after 3 years. Expensive but worth it in the long run.
