SLP Loudmouth II Exhaust, Loud Mouth II 99-04 Mustang GT/MACH 1.
SLP’s Mustang cat-backs from LMPERFORMANCE have always been the
best-performing exhaust systems in the business. Now they’re the most versatile,
too! Using groundbreaking modular technology first seen on our Mustang X-pipes,
we’ve developed a line of systems that can be quickly reconfigured to fit
changing performance, noise-level, and sound-quality requirements. Simply loosen
a few band clamps, swap muffler types, retighten, and you’re done. No other
exhaust offers this level of performance and adaptability!
Along with
the included race mufflers, the Loud Mouth II system is compatible with our
original Loud Mouth™ resonators (#31062) and our all-new, straight-through-type
Power-Flo™ traditional mufflers (#31065). Buy all three for complete control
over your Mustang’s sound and performance characteristics.
