2009-2013 Corvette LoudMouth II Exhaust System

Bolt a LoudMouth II® Axle-Back Exhaust System onto your 2009-2013 C6 Corvette/Grand Sport for gains up to 12 extra horsepower. The tone is deep and powerful letting everyone know you're coming, with an aggressive rumble your LS3 deserves. The secret to the system's distinctive sound and performance gains are a pair of polished stainless SLP bullet-style mufflers, stamped with our SLP logo. This system features four polished 3.5" dual split round tips, providing you with the ultimate Corvette look. The modular design gives you flexibility to change to our louder SLP resonators (#31062). The rest of the exhaust system is hand-crafted from 2.5" 304 stainless steel
