This exhaust flange is used in our 3" exhaust systems. It is CNC waterjet cut from 3/8" thick 1018 cold roll steel or 304 stainless steel. Standard through-bolt holes have been replaced with radial slots to create an adjustable connection.
This flange is available for those who wish to connect their existing exhaust system to any of our 3" exhaust products. Gaskets and hardware are available separately.
