SLP Exhaust System, ''Loud Mouth II'' 2004 GTO.

SLP’s new GTO PowerFlo 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 PowerFlo is hand-built from 100 percent stainless steel and carries a limited lifetime warranty.
