Description

If you're looking for the best-flowing, meanest-sounding exhausts in the business, then SLP Performance Loud Mouth exhaust systems are for you. Many models use a specially designed resonator instead of a traditional muffler, allowing them to provide unmatched power increases and a wicked "wide-open" sound. Others are axle-back style without mufflers or resonators. Choose the exhaust best-suited for your vehicle. Gains of up to 25 hp are possible, depending upon the application. You'll feel and hear the difference with an SLP Loud Mouth exhaust system!
