The Stainless Works collector adapter is a TIG-welded 304 stainless steel exhaust transition with a 3" 3-bolt flange and a 2-1/4" OD outlet, built to resist corrosion and hold up under heat and vibration. An O2 bung is welded into the tubing roughly 2" from the flange’s inside edge for sensor installation. The adapter includes a limited lifetime warranty and is made in the USA.
