2004 GTO 5.7L V8 SLP Exhaust System, "Loud Mouth II" w/PowerFlo-X Crossover Pipe
2004 GTO 5.7L V8 SLP Exhaust System, "Loud Mouth II" w/PowerFlo-X Crossover Pipe ,
SLP's new GTO Loud Mouth II exhaust system employs an integral X-pipe crossover and dual low-restriction mufflers to provide superior flow and performance, while minimizing interior resonance. Expect a smoother, mellower tone than that of our Loud Mouth system, along with a subtly aggressive edge under hard acceleration. Like all SLP exhaust systems, the GTO Loud Mouth II is hand-built from 100 percent stainless steel and carries a limited lifetime warranty.
