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
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.

this their “Passive” system. Meaning, the outside tips are open and
free-flowing all the time and the inner two tips are bolted onto the
muffler with a removable block-off plate that is pre-installed from
Roush to limit sound and flow. The end user can easily remove this
plate in a matter of minutes to reap the full benefits of both sound
and performance from their new quad tip Roush mufflers. Roush is in the
works of releasing what they call an “Active Exhaust Module” that will
install in the location of the block off plate. This kit will convert
the passive system to an active system, giving you the ability to
actively control the sound level and exhaust flow coming from the inner
