Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4451208. 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 to fit the 2003 Chevrolet Venture, 2003 Buick Rendezvous, and additional vehicles. 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.

Great sublimation paper
Size: 120g 8.5" x 14"
I like using this paper and have purchased numerous times. The one I buy the paper is a little thicker and the designs print beautiful vibrant colors.

Works Very Well
Size: 120g 8.5" x 11"
I am new to sublimation printing, and purchased this based on recommendations from multiple websites. I'm so glad I did! It transfers well onto several mediums, including shirts, totes, mousepads and cups. I've never had any jams or misfeeds, and the quality of the paper is high. I'll definitely purchase again!

Great protection from super glue spills
Size: 11"×17" 20Sheets & 8.5"×11" 10Sheets, Color: Teflon Paper
I work a lot with super glue and found that these work very well when covering work surfaces. Super glue will not permanently stick the Teflon sheets and in most cases are reusable.
