Description
For Louder and Deeper Tones. This Roush Axle-Back Exhaust with Black Tips, which is designed exclusively for AmericanMuscle, is designed to produce louder and deeper exhaust tones. It features a healthy rumble at idle, which builds to a powerful roar when you step on the pedal. Enjoy a drone-free experience inside your Mustang's cabin, while you get powerful and aggressive tones outside.
Enjoy Maximum Performance. Get the best out of your Ford Mustang GT with this Axle-Back Exhaust upgrade. Featuring full mandrel bending, this exhaust assembly offers a constant inner diameter without any kinks or creases for that smooth performance. The assembly is also designed with reduced back pressure in the system and improved exhaust flow. As such, you get increased horsepower and maximum performance.
Exceptional Quality. Designed for guaranteed performance and long-lasting service, this exhaust assembly is comprised of high-quality components. From the mufflers to the equipped mounting clamps, these are all constructed from corrosion-resistant T-304 stainless steel material. The tips are 4-inch, black, dual wall tips, which are unique. You can rest assured that this exhaust assembly can withstand years of abuse and still look great and perform like new.
No-Welding Installation. Getting this axle-back exhaust mounted to your Mustang requires some cutting. You need to cut through the factory muffler and tip assembly so you can slide in the new ones. No welding and drilling needed as you will use your vehicle’s factory hangers and mounting points.
Backed By Limited Lifetime Warranty. This axle-back exhaust is backed a limited lifetime warranty from Roush. The warranty coverage starts from the date of purchase and covers for defects in materials and workmanship only. The coverage starts from the date of retail purchase by the original purchaser for the original vehicle on which the product was installed. Proof of purchase required for warranty coverage.
Application. This Roush Axle-Back Exhaust with Black Tips is specifically designed to fit 2024-2025 Ford Mustang GT Models without Active Exhaust.
