What is the primary benefit of a cat-back exhaust system?

A cat-back exhaust system replaces the factory exhaust components from the catalytic converter back. This generally leads to improved exhaust flow, reduced back pressure, and a more aggressive, performance-oriented sound from your engine.

What material is this Roush exhaust system made from?

This Roush cat-back exhaust system is constructed from 304 stainless steel. This material is well-known for its resistance to corrosion and its durability, making it a great choice for exhaust components.

Does this exhaust system include everything needed for installation?

This kit includes the x-pipe, mid-pipes, mufflers, and exhaust tips. While it's designed as a direct replacement for the factory cat-back section, you should always refer to the manufacturer's installation instructions for any additional hardware or specific procedures.

Product Details

If you're looking to give your 2018-2023 Ford Mustang GT with the 5.0L V8 engine a more aggressive sound and a noticeable boost in performance, this Roush cat-back exhaust system is a solid choice. It replaces the factory exhaust from the catalytic converters back, including the mufflers and tips, to really let that V8 engine breathe and sing.

This system is built from corrosion-resistant 304 stainless steel, so it's made to last. The pipes are mandrel-bent, which means they maintain a consistent diameter throughout the bends.

You'll get a distinct Roush performance sound, thanks to the dual high-flow mufflers and the included x-pipe, which helps to smooth out the exhaust pulses for a cleaner tone. The polished 304 stainless steel tips give the rear of your Mustang a sharp, performance-oriented look.

When installing this system, it's always a good idea to check your local noise ordinances to make sure you're compliant. This kit is designed specifically for the Fastback models of the 2018-2023 Mustang GT.
