      For an Aggressive Growl. Featuring straight-through design, this Roush Extreme Axle-Back Exhaust with Black Tips, which is designed exclusively for AmericanMuscle, is much less restrictive and therefore, gives off tough and deeper sound. With this installed on your Mustang, you get to enjoy aggressive growls and roars as you step on the pedal while still maintaining a comfortable and drone-free cabin experience.

      Improved Overall Performance. This axle-back system offers a complete exhaust redesign and boosts in speed and acceleration. Designed using CAD data from OEM manufacturing, this exhaust system offers a perfect fit and can even be used with your Mustang’s factory rear valance. With straight-through resonators, there’s less restriction in this exhaust so you can easily achieve increased horsepower and overall improved performance.

      High-Quality Construction. This exhaust assembly is comprised of high-quality components that are manufactured using 304 stainless steel material. The tips are painted black for superior look and durability. All these components are guaranteed to have great resistance to corrosion and can withstand years of abuse.

      Straightforward Installation. Getting this axle-back exhaust installed should not be difficult since these are designed for direct-fit applications. Simply unclamp the old ones and slide in the new exhaust kit using the supplied hardware. No welding and drilling needed.

      Backed By 3-Year Limited Warranty. This axle-back exhaust is covered by a 3-year limited warranty from Roush. The coverage starts from the date of retail purchase and includes defects in materials and workmanship. You need to present a proof of purchase for warranty coverage.

      Application. This Roush Extreme Axle-Back Exhaust with Black Tips is specifically designed to fit all 2005-2010 Ford Mustang GT and GT500 models.

        Perfect sound

        I was a little hesitant and it was a very hard decision deciding from all of the different exhaust options. But after a little research this was an awesome choice. My GT sounds great
