Bolt on a Loud Mouth® Axle-Back Exhaust System from SLP on your 2010-2013 C6 Corvette/Grand Sport for gains up to 12 extra horsepower. The tone is rich 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 Loud Mouth resonators, 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 quieter Loud Mouth II® bullet-style mufflers. The rest of the exhaust system is hand-crafted from 2.5" 304 stainless steel, and is covered with our Limited Lifetime Warranty.
