Bolt on a LoudMouth II® Cat-Back Exhaust System on your 2005-2007 Cobalt SS for significant horsepower gains over your stock restrictive 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 SLP 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 SLP resonator (# 31062). The rest of the exhaust system is hand-crafted from 2.5" stainless steel, comes complete with hardware, detailed installations and is covered with our Lifetime Warranty.
