SLP 04 GTO "Loud Mouth" Exhaust System w/X-Pipe

Looking for the ultimate GTO cat-back system? Lethal Performance introduces SLP's new GTO Loud Mouth employs an integral X-pipe crossover and specially designed "Shotgun" race resonators to provide superior flow and performance, while minimizing interior drone. The resulting tone is deep, rich, and powerful--the consummate fusion of muscle-car aggression and grand-touring civility. Like all SLP exhaust systems, the GTO Loud Mouth is hand-built from 100 percent stainless steel and carries a limited lifetime warranty.
