Description

Flowmaster FlowFX exhaust systems are a "sound" choice for your vehicle. Delivering a moderately aggressive tone, they're built with bright 409S stainless steel tubing, and FlowFX straight-through mufflers with large cores for maximum performance and a deep sound. Many systems also include 304 stainless steel tips finished in a black ceramic coat or polished, and embossed with the Flowmaster logo. Flowmaster FlowFX exhaust systems are designed for ease-of-installation, and include all necessary parts, hardware, and detailed instructions. Choose the style, pipe size, muffler quantity and configuration for best fitment on your vehicle.
