This Diamond Eye stainless-steel exhaust adapter steps from a 3.5-inch inner diameter to a 4.0-inch inner diameter over a 6-inch length, providing a straightforward junction for exhaust runs that require those sizes. Constructed in stainless steel (SS) and sized for welding or clamping, it is intended to join mismatched pipe diameters and simplify exhaust routing when transitioning between 3.5" and 4.0" sections.
