Roush Performance Exhaust System Kit

Roush Performance Exhaust System Kits: Engineering the Perfect Sound

Few names in the Ford performance aftermarket carry the same weight as Roush Performance. When it comes to exhaust system kits, Roush doesn't simply bolt on louder pipes — they engineer the entire acoustic and performance experience from the ground up, leveraging decades of motorsport expertise and their own in-house testing facilities.

Built from the Ground Up: Materials and Construction

Roush exhaust systems are crafted from 304 stainless steel, known for its anti-corrosion properties, ensuring long-lasting durability. Every kit is mandrel-bent for precision and increased airflow, a manufacturing method that maintains consistent pipe diameter through every bend to eliminate the flow restrictions common in crush-bent systems. Included in the package are a mandrel-bent x-pipe, mid-pipes, and dual high-flow mufflers, all contributing to an enriched sound profile and elevated performance characteristics.

Cat-Back Systems: Performance Without Compromise

Roush cat-back exhaust kits are available for an extensive range of Ford platforms. Mustang exhaust kits cover model years 2005 through 2024, with options offering aggressive sound with up to a 12 lb. weight reduction over stock. For truck owners, F-150 exhaust kits deliver increased airflow, reduced back pressure, and a signature aggressive tone. Systems install easily using OEM hangers and mounting points — no welding required.

Active Exhaust Technology: Four Modes, One Powerful System

What truly separates Roush from the competition is their patented Active Exhaust platform. The Roush Active Exhaust gives drivers the ability to "tune" their exhaust note using an iOS application and vehicle parameters for virtually infinite sound possibilities. The system utilizes digitally controlled actuators that can be mapped through an OBD2-based Wi-Fi interface to adjust the exhaust flow.

The Roush Active Exhaust system features four modes: TOURING, SPORT, TRACK, and CUSTOM. TOURING mode closes the exhaust tailpipe valves completely and keeps the exhaust volume at its absolute minimum. TRACK mode is the loudest of the modes — it keeps the Active Exhaust valves fully open at all times when the engine is running. CUSTOM mode allows the operator to employ an iOS application and Wi-Fi module attached to the vehicle's diagnostic port to personalize the exhaust sound for unique calibration.

Engineered and Tested In-House

The Roush Active Exhaust was designed and manufactured in-house at Roush Performance. Roush engineers have full access to their own high-tech manufacturing and testing facilities, including a state-of-the-art semi-anechoic NVH (noise, vibration, and harshness) lab. This level of internal R&D means every exhaust system kit is validated for both sound quality and real-world performance before it reaches customers.

Warranty Backing You Can Count On

Roush Active Exhaust Kits carry a Lifetime Muffler warranty from the date of retail purchase, except on electrical components. This long-term coverage reflects the confidence Roush places in their own engineering and materials.

Whether you're building a track-day Mustang or simply want your daily-driven F-150 to announce itself with authority, Roush Performance exhaust system kits offer the engineering pedigree, material quality, and technological innovation to deliver a driving experience unlike anything from the factory.
