SLP 99-04 Cobra "Loud Mouth II" (modular) Exhaust System

The best-performing cat-backs in the business are now the most versatile, too! Using groundbreaking modular technology first seen on our Mustang X-pipes, weve developed a new line of exhaust 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 youre done. No other cat-back offers this level of performance and adaptability!

This system includes our all-new Loud Mouth II race mufflers, which combine flow characteristics similar to those of our original Loud Mouth resonators with a deeper tone and reduced resonance. Get both for complete control over your Cobras sound and performance characteristics.
