    Manufacturer's Part Number:

    Give your car the wild howl of American muscle that it deserves with these ROUSH Mustang Exhaust Kits.
    The mufflers of these kits features ROUSH's unique and innovative open-chambered design. This differs substantially from the conventional fiberglass-packing found in other mufflers. The result is a less inhibited sound, increased air flow (maximizing power), and increased longevity (there is no fiberglass that would break-down over time). Another great feature of this exhaust kit is the lack of the typical in-cockpit boom at cruising speeds found with most performance exhaust systems.

    Not only is the sound high-quality with the ROUSH Mustang Exhaust Kit, but the looks are as well. The tips are made from high-quality 304 stainless steel and are finished with a special chrome flashing process. The problem with conventional chrome plating is that the layers of bonded chemicals (which achieve its shiny appearance) are susceptible to cracking and flaking, especially when subjected to heat (as is found with an exhaust). The chrome flashing used in for this Mustang exhaust is bonded micro-porously to the metal surface. The result is a finish that is highly resistant to cracking from localized damage and heat color change. The inlet pipe and mufflers are made from 409 stainless steel for enhanced durability.

    Installation of the ROUSH Mustang Exhaust Kits is quick and easy. The exhaust uses the factory hanger mounting positions (you won't have to fabricate your own). These kits also features new OE-quality spherical clamps for a great fit.
