Product Information-

SLP PT# 31060

Looking for the ultimate GTO cat-back system? 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.

  • Constructed entirely from mandrel-bent stainless steel (2.5" OD)
  • Equipped with an integral X-pipe crossover for optimum performance and sound quality
  • Custom-designed "Shotgun" race resonators provide virtually unrestricted exhaust flow
  • Exclusive modular design allows easy interchangeability between resonators
    and SLP high-flow mufflers
  • Features two hand-polished, double-wall tips
  • Designed to OEM standards of fit and durability
  • Covered by our limited lifetime warranty
  • Priced significantly less than competitors' stainless systems

Should you get a Loudmouth I or II?

SLP's Loudmouth I (the item offered in this sale) exhaust utilizes SLP's unique shotgun resonators offer a very loud muscular sound similar to many power boats out there. These mufflers are very high flow, but are also loud enough to get unwanted attention at times.

SLP's Loudmouth II exhaust utilizes a straight through bullet muffler, which produces a deeper, less raspy sound than the Loudmouth I. While the Loudmouth II is quieter and will comply with most noise pollution laws, it is still one of the louder exhausts you can buy.
