Dinan Resonator Delete Kit - 3.25in - Stainless Steel - BMW F22 M235i

The Dinan Resonator Delete Kit for the BMW F22 M235i replaces the factory resonated section between the catalyst and rear muffler with 82.6mm mandrel-bent T304 stainless steel tubing, stepping up from the stock hydro-formed 80mm pipe. The mandrel-bent construction maintains consistent interior diameter through any bends, reducing restriction compared to stamped alternatives. The result is a more free-flowing exhaust path, increased volume, and a more aggressive exhaust character while retaining the rest of the factory exhaust system. All mounting hardware is included for a bolt-on installation.
