The Stainless Works collector adapter with a 3-1/2" inlet and 3-1/2" outlet is a straight-through TIG-welded 304 stainless adapter with a 3-bolt flange for matching diameter connections. Its robust stainless construction resists corrosion and provides a solid flange-to-pipe interface for exhaust assemblies. Made in the USA and covered by a limited lifetime warranty, it simplifies joining like-sized collector and exhaust tubing.
