Review FLOWMASTER Exhaust System Kit

The Flowmaster 817658 Exhaust Kit is an ideal upgrade for your vehicle, designed to deliver exceptional performance and a bold, distinctive sound. This exhaust system is engineered for select Ford applications, ensuring a perfect fit and optimal functionality.

The core of this exhaust kit lies in its 1 -inch mandrel-bent tubing. Mandrel bending ensures a smooth, uniform shape throughout the length of the piping, allowing for maximum exhaust flow and reduced backpressure. The tubing is constructed of 304 stainless steel, providing superior strength and durability against rust and corrosion.

The exhaust system comes with a high-performance Flowmaster muffler. This muffler features a unique internal design, which includes a series of chambered resonators. These resonators work in conjunction with the muffler's deep-flowing core to produce a deep, resonant exhaust tone. The muffler's inlet and outlet are CNC mandrel-bent for a perfect fit, and it is also constructed of 304 stainless steel for longevity.

The Flowmaster 817658 Exhaust Kit also includes high-quality exhaust hardware, such as clamps, gaskets, and bolts, all made of stainless steel to ensure a long-lasting installation. The kit is designed to be a direct replacement for your factory exhaust system, making for a straightforward and hassle-free installation process.

Upgrading your exhaust system with the Flowmaster 817658 Exhaust Kit not only enhances the performance of your vehicle but also gives it a unique, aggressive sound that sets it apart from the rest. The kit is backed by Flowmaster's limited lifetime warranty, ensuring your peace of mind with your purchase.
