Bolt on a Loud Mouth II™ catalyst-back exhaust system from SLP on your 2005-07 Cobalt SS for significant horsepower gains over your stock restrive exhaust system. The tone is deep and powerful letting everyone know you're coming, with an aggressive rumble. The secret to the system's distinctive sound and performance gains is a polished stainless Loud Mouth II™ bullet-style muffler, stamped with our SLP logo. This system features a polished 4" double wall round tip, providing you with the ultimate Cobalt look. The modular design gives you flexibility to change to our louder Loud Mouth™ resonator (# 31062). The rest of the exhaust system is hand-crafted from 2.5" 304 stainless steel, comes complete with hardware, detailed installations and is covered with our Lifetime Warranty.
