Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-812. 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 2017 Audi Q7 and interchanges with OE part 4M0 254 200 NX. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Size: 4x9.5inch
First, the sizing is absolutely perfect for these projects. Instead of wasting large sheets and having to cut them down, these pre-cut sizes save a ton of time and effort — and most importantly, reduce paper waste. The quality of A-Sub paper has always been excellent: it holds vibrant colors beautifully, releases ink consistently, and produces crisp, sharp designs. Both of these sizes continue that tradition. I’ve noticed my images transfer smoothly and evenly every time, whether I'm working on ceramic mugs or glass tumblers. In terms of value, these smaller sheets are definitely worth the price. You get professional-quality results without using more paper than you need, which in the long run saves money and materials. Overall, I highly recommend these A-Sub sublimation papers for anyone looking to streamline their mug and tumbler production. They’re efficient, reliable, and a great investment for any sublimation business or hobbyist. - send me stuff to review.

Best Choice for Sublimation Paper
Size: 13x19inch
I'm just a beginner but have been doing sublimation for about a year. Of all the papers I have tried, A-Sub is by far the best for color transfer and ease of use. I also use A-Sub for my photo printing. I am now a firm believer in their products and don't see changing.
