Get maximum flexibility from your SLP cat-back with these "Shotgun" race resonators. Standard equipment on many of our Loud Mouth systems, they make it possible to switch between muffled and "wide open" exhaust configurations in a matter of minutes. All resonators are constructed from hand-polished 304 stainless steel and embossed with the classic SLP logo.

NOTE: Sold in pairs. May also be used in the fabrication of custom exhaust systems (4" body, 2.5" inlet, 2.5" outlet). Does not fit 3" F-Body system.
