    Flow Path Mufflers. MAC Flow Path Chambered Mufflers feature a patented multi passage design, following Helmholtz's Theory of Tone, to produce a muffler that effectively flows exiting exhaust gases all while maintaining a desirable tone. With no packing that can burn out, Flow Path Mufflers will sound the same mile after mile, year after year.

    High Quality Construction. Mandrel bent from durable 2.5" aluminized steel tubing for strength and corrosion resistance, this MAC Performance Cat-Back features two "Flow Path" chambered mufflers with turn down tips to match the original factory GT appearance.
