  • Mandrel bending maintains a constant inner diameter with no kinks or creases.
  • This improves exhaust flow and reduces backpressure in the system.
  • This system includes single tip High flow mufflers that improve the stock sound of the Mustang V8 This system will produce louder deeper exhaust tone, with a healthy V8 burble at idle, building to a powerful roar at high revs. Check your local noise ordinances for legality.

Vehicle Fitment

  • Ford Mustang 2015–2017

Please confirm the model year, trim and engine size against your vehicle before ordering — Roush parts differ between engine options (for example 2.3L, 3.7L and 5.0L), and some exhaust kits are specific to vehicles built with or without the factory active exhaust system.

Manufacturer's Warranty — Roush

ROUSH warrants ROUSH® retail parts and accessories — including exhaust systems and air induction systems — against defects in materials and workmanship for 90 days from the date of retail purchase by the original end-user purchaser from an Authorized ROUSH Performance Dealer, and proof of purchase is required. ROUSH® wheels are covered separately — the finish is warranted for the earlier of one year or 12,000 miles (19,500 km). ROUSHcharger® / supercharger kits 421432, 421435, 421542, 421984, 422184 and 422337 carry a parts-only 3 year / 36,000 mile (60,000 km) warranty from the date of original installation, limited to ROUSH® components and to the original vehicle owner; it is not transferable, and it is void without premium fuel of at least 91 octane (R+M)/2 or with oil-change intervals longer than 5,000 miles. Some supercharger kits also offer an optional Limited Powertrain Warranty sold separately — ask before you buy. You must register the part online within 30 days of the installation date on your service order for any of this coverage to activate. ROUSH services its own parts: open a case at 1-800-59-ROUSH (1-800-597-6874) or rppcase@roush.com before any work begins, because unauthorised work may not be paid. ROUSH covers the part only — installation and removal labour are not covered, and neither is sound, which ROUSH does not warrant because it is subjective. Also excluded are normal wear and improper installation, road hazards, abuse and neglect, racing and overloading, altering or disassembling the part, non-ROUSH® approved components such as headers or converters, and caustic cleaners on painted, vinyl-striped or metal-finished surfaces. Appearance change is excluded by design — 409 stainless discolours and black-painted exhaust tips fade with thermal cycling, and neither is a warrantable defect. Coverage is valid in the United States and Canada and is governed by the laws of Michigan. Installing aftermarket parts may affect an OE warranty.

Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by Roush. Contact us if you need help with a warranty claim.
