Aggressive Exhaust Tones. With this Roush Axle-Back Exhaust with Black Tips, which is designed exclusively for AmericanMuscle, you are bound to experience a drone-free cabin, while your Mustang EcoBoost is roaring with a powerful tone outside. It’s an exhaust assembly that’s perfect for Mustang enthusiasts craving for a more aggressive tone and deeper exhaust sound whenever you step on the pedal.
Performance-Grade Exhaust. This axle-back exhaust is the best way to get your exhaust system up to speed with your Ford Mustang’s high-powered engine. Designed to give your vehicle an aggressive tone and sleek look, this exhaust assembly features embossed tips and mandrel bent mufflers. What you get is an exhaust system that offers high flow and reduced back pressure for better performance.
High-Quality Construction. Roush is a leading brand name when it comes to high-performance and quality exhausts. In fact, this axle-back assembly is comprised of components that are constructed from high-grade T-304 stainless steel. As such, you can rest assured that these exhaust components are corrosion-resistant and can withstand years of abuse. The dual-wall exhaust tips are black, a unique feature only for AmericanMuscle.
Minor Cutting Required. Although the components in this exhaust system are designed to fit your EcoBoost, some minor cutting will still be required during installation. Using a reciprocating saw, you need to cut the factory exhaust pipe in order to insert this Roush exhaust. No welding or drilling needed as this assembly simply uses existing factory hangers and mounting points.
Roush Limited Lifetime Warranty. Roush offers a limited lifetime warranty for this axle-back exhaust system. The warranty coverage shall start from the date of retail purchase and covers for defects in materials and workmanship. An original proof of purchase is required to be eligible for warranty coverage.
