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 American 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 does require cutting of the factory system and includes all necessary parts and hardware for easy installation.

  • Dyno tuned for maximum performance
  • Axle back system
  • Includes hangers and hardware for easy installation
  • Aggressive and powerful exterior exhaust tone
  • Mandrel bent 16 gauge 409 stainless tubing

Regarding order 708:

I would order from Autoplicity again without hesitation. The order process was simple and I received my order within a few days. I am very happy with my purchase.
Completely amazed by this seller.  I recieved the rack in just 2 days and the price was unbeatable.  I'm just stoked to have finally found a bike rack worth having!!
