Will this exhaust kit fit my 2009 Mustang GT with the factory rear fascia?

Yes, this Roush cat-back exhaust kit is designed to fit 2005-2009 Ford Mustang GT and GT500 models that have the factory rear fascia. The 4-inch polished tips are intended to complement the stock appearance.

What is the primary benefit of the CNC mandrel bends used in this exhaust?

The CNC mandrel bends maintain a consistent inner diameter throughout the exhaust tubing, even in the curved sections. This smooth flow path significantly increases exhaust gas velocity and volume compared to stock or serrated-bent pipes, leading to improved horsepower and torque.

Does this exhaust kit include all the necessary hardware for installation?

This Roush cat-back exhaust kit is designed as a direct bolt-on replacement for your factory system. While it includes the main exhaust components, it's always recommended to refer to the manufacturer's installation instructions to confirm if any additional hardware or clamps are needed for a complete installation.

Product Details

This Roush cat-back exhaust kit is built using 2.5-inch diameter stainless steel tubing, formed with a CNC bender for smooth, mandrel bends. This design maintains a consistent inner diameter through the bends, which is key to increasing exhaust flow compared to stock or serrated-bent pipes. The result is a noticeable increase in both horsepower and torque for your 2005-2009 Ford Mustang GT or GT500, along with a deeper, more aggressive exhaust note that lets everyone know you mean business.

While this system is designed to produce a robust sound outside the vehicle, the engineers at Roush have worked to minimize the common issue of interior exhaust drone. You'll enjoy the enhanced sound without the annoying resonance on longer drives. The kit features 4-inch diameter polished 304 stainless steel tips, each embossed with the distinctive "ROUSH" logo, adding a sharp visual upgrade to the rear of your Mustang. This cat-back system is designed to fit Mustangs equipped with the factory rear fascia.

Installation of this system is straightforward as a cat-back replacement, meaning it connects to your existing catalytic converter. You'll want to ensure you have the proper tools and a safe workspace for installation. This kit is a popular choice for Mustang owners looking to significantly enhance their vehicle's sound and performance.
