This muffler differs substantially from the conventional fiberglass-packing found in other mufflers. The ROUSH muffler produces 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.

The result is a finish that is highly resistant to cracking from localized damage and heat color change. Conventional chrome plating are susceptible to cracking and flaking, especially when subjected to heat (as is found with an exhaust) The inlet pipe and mufflers are made from 409 stainless steel for enhanced durability.

This kit carries a 3 year limited warranty and has no negative effect on emissions.
