Description

SLP Performance knows all about getting the maximum performance for your ride. That's why they designed the Loud Mouth II race mufflers. These exhaust components offer flow and performance similar to that of the original Loud Mouth resonators, but feature a ceramic-wrapped, perforated core that reduces high-frequency noise and in-car resonance. Each Loud Mouth II muffler is constructed from hand-polished 304 stainless steel. They're available with different inlet/outlet sizes, as well as individually or in pairs.
