Show original supplier description
The SLP LoudMouth Cat-Back Exhaust System is engineered to enhance the performance and sound of your 1998-2002 Chevrolet Camaro LS1 or Pontiac Firebird. The system is built for direct bolt-on installation, replacing the entire exhaust from the Y-pipe back. The stainless steel construction ensures longevity and resistance to corrosion. Fitment is specified for all 1998-2002 Chevrolet Camaro and Pontiac Firebird models equipped with the LS1 engine, including Base, Z28, Z28 SS, Formula, and Trans Am trims. Installation involves removing the existing exhaust system from the Y-pipe outlet back and securing the new system using the provided hardware or existing clamps.
