This is a video showing what my Magnum sounded like before and after I had an SLP Loudmouth 1 cat-back exhaust system installed. Before it was installed there was only a K&N CAI on the car, but now there is a K&N CAI, an SLP LM1 system, a Jet 180 degree t-stat, and it has a 93 Octane CAI Predator tune.
