Product Description

This 2.5 Inch Flowmaster American Thunder Axle-Back (single rear exit) exhaust is designed for 2005-10 Mustang V6 4.0.  It's constructed from 409S Stainless Steel to resist corrosion and utilizes a Flowmaster Delta Flow 60 Series Muffler for an aggressive exterior sound.

This aggressive sounding system is designed to replace the original rear mounted mufflers located behind the rear axle. With easy fit in mind, the system is mandrel bent for maximum performance and includes specially selected mufflers to support the performance image of the car. As an America Thunder system, it delivers an aggressive exterior tone with moderate interior sound level that is suited to the enthusiast who wants their performance to be heard. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, the system includes all necessary parts and hardware for easy installation.
