Give Your Edge ST the Voice It Deserves
The 2019 to 2024 Ford Edge ST hides a genuinely quick twin turbo V6 behind an exhaust note that stays quiet no matter how hard you push it. The B933-C933 catback system from Thermal R&D swaps in full 2.5 inch T304 stainless steel piping and a three canister muffler layout, giving the Edge ST a deeper, more aggressive voice while true Helmholtz tuning keeps highway drone out of the cabin.
