SLP Loudmouth II Exhaust System - 2004 Pontiac GTO

$713.74

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