The Dinan Resonator Delete Kit removes the hydroformed factory resonated section and replaces it with 3.25in (83mm) T304 stainless steel tubing for freer flow. In place of the resonator, a mandrel-bent X-pipe crossover promotes even flow to both banks of tips and smooths the uneven-flow harshness of the stock system, adding volume for a louder, smoother, fuller sound. The tubing wears a brushed finish and installs bolt-on with the included mounting hardware.
