You asked for it, and we were listening! In response to overwhelming popular demand, we’ve developed an all-new system that combines the classic tone of a straight-through muffler design with the superior performance and quality you’ve come to expect from SLP. Built entirely from high-luster stainless steel; the Mustang Power-Flo™ features 2.5 mandrel-bent tubing; two ultra-low-restriction SLP mufflers; and a pair of our signature hand-polished, dual-wall tips. Includes detailed instructions and all required installation hardware.
Applications:
1999 - 2004 Ford Mustang

specifications. Loudmouth also refers to some systems without any resonators such as the 2010 Camaro Loud Mouth and the 2005 Mustang Loud Mouth Axle backs where the mufflers are removed altogether. Images below are representations in order to better understand the differences.
