Improve the exhaust flow on your 1999-04 Mustang 4.6 with this stainless steel Flowmaster American Thunder cat back. Flowmaster American thunder cat backs provide maximum exhaust flow with a deep throaty muscle car sound with less interior resonance. This cat back provides better acceleration and increased horsepower by reducing back pressure through the mandrel bent tubing.
Flowmaster American Thunder cat backs are designed using mandrel-bent 16-gauge stainless steel steel tubing. The 409 stainless steel protects against rust and corrosion for a long worry free live. This 2.5" mandrel bent tubing allows for superior exhaust gas flow for great sound and performance. Installation hardware gaskets and instructions are included for an easy installation.
