FlowMaster American Thunder Cat-Back

The Flowmaster Sound is the true tone of American muscle and performance. Available in a wide range of domestic and import applications for automobiles and trucks. Flowmaster mufflers produce more power than OEM and competitive aftermarket products.

What makes Flowmaster so unique is that its performance improvement is paired with our unique exhaust tones. The “Flowmaster Sound” is offered in many different tones depending upon the muffler series. From the deep, aggressive tone of the 40 Series to a quiet and subtle, but unmistakably rich Flowmaster tone of the 70 Series, you will find the right application of performance and exhaust sound you want.

Flowmaster's systems will improve acceleration and passing power, as well as help improve fuel mileage. Every system is individually engineered and dyno-tested for each application and includes all required mounting hardware

All tubing is mandrel bent for superior exhaust gas flow, and is a key to the system's performance improvements.

 

Both mufflers and tubing are fabricated from aluminized steel for corrosion resistance

Flowmaster's systems are designed with the latest technology to provide even better performance than a single Flowmaster muffler installation.


 

Looking for the famous, full-on "Flowmaster tone?" Look no further. American Thunder will deliver the aggressive tone you want, as well as the performance you demand
