Type 4 Resonator Rear Exhaust Kit

440 / 550 Type 4 Resonator Rear Exhaust Kit

This resonator kit features a single design compatible with 440/550, incorporating a J-tube and an in-hull resonator design. It utilizes perforated stainless steel tubing rather than aluminum to enhance sound dampening and prevent internal damage (no more broken internals). The kit is designed to work with the OEM adjustable mount (not included).

The Type 4 is a 2 1/4" J-tube with a 2 1/2" ID resonator. 

To install the hull must be cut into to remove the stock exhaust and to replace it with the in-hull resonator. The amount of cutting and cutting location depends on make and year of the ski, see instructions for more details.  

Resonators are the only true performance (tunable) exhaust system.

Kit comes with 1 silicone coupler and 2 clamps.
