The ROUSH Resonator Delete X‑Pipe for 2015–2023 Mustang GT 5.0L increases exhaust flow and produces a race‑inspired tone by removing the factory resonator. The 2.5" mandrel‑bent stainless assembly improves flow and reduces back pressure while remaining compatible with Ford's factory active exhaust. Engineered with OEM CAD data for a direct fit, the X‑Pipe is a quick, durable way to sharpen sound and support gains in horsepower and torque.
