Roush exhausts are developed alongside Ford engineers to deliver a signature, aggressive exhaust character that transforms the V6 Mustang's sound profile — a deep, throaty note under acceleration that remains refined at idle and cruise. The black tip finish adds a purposeful, blacked-out aesthetic to the Mustang's rear end. Axle-back installation means no tune is required — a straightforward bolt-on upgrade that transforms the V6 GT's exhaust note without touching the front of the exhaust system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e⚠️ V6 Specific – Not Compatible with Mustang GT (5.0L):\u003c\/strong\u003e This exhaust is engineered specifically for the \u003cstrong\u003e2011–2014 Mustang V6 (3.7L Cyclone)\u003c\/strong\u003e.
