I have a 2015 Mustang GT with headers and resonator delete. So it wouldn’t be so loud in the mornings I installed the Roush active exhaust. I have had the kit for 5 years and now the valves rattle. It’s sounds horrible. I reached out to Roush and was told I would have to buy whole new adapters with actuators at $400 a piece. Anyone have a idea how to fix this?
