Get ready to rumble when you install a "Loud Mouth" rear axle (aka axle back) exhaust system from SLP Performance Parts on your exhaust pipes! This affordable, easy to install kit eliminates the factory mufflers on your Ford Mustang or 2010 Chevy Camaro entirely, drastically reducing backpressure for enhanced power, torque, and a mind blowing high performance sound. Nothing elese even comes close!
