These 4.5 street compliant high-flow mufflers have been specifically tuned to deliver an aggressive exhaust note and improved performance. The straight-through perforated baffle reduces airflow restriction, and produces a rich exhaust note throughout the entire RPM range. You get a great performance, a powerful base rumble and a throaty tone while on the throttle, while maintaining a mellow note while cruising.
