The header does great, but does even better with the stuff behind it. We tested the first header (1.5-1.625) with a stock car and saw power at the top and midrange but haven't had a chance to test the new header on its own. As soon as we pull it off and switch to the next design we'll throw it on another local stock car here and get some dyno data with the header alone. I need to look into the SARD parts (and their tagline 'Be Improved by SARD'). Always have loved them. Met up with one of their silicone manufacturers (Contitech / Continental in Korea) when I worked at a previous shop. They pull out the stops when it comes to quality. IIRC, their silicone couplers were like 4.5mm thick and had 3 tightly stacked layers of reinforcement. Doing it right.
