SLP’s Cobra Loud Mouth has always been the best-performing cat-back exhaust in the business. Now it’s the most versatile, too! Using groundbreaking modular technology first seen on our Mustang X-pipes, we’ve developed a system 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 system offers this level of performance and adaptability!
Along with the included resonators, the Cobra Loud Mouth system is compatible with our all-new bullet-type Loud Mouth II race unit. Buy both for complete control over your Cobra’s sound and performance characteristics.
NOTES: Includes Loud Mouth resonators. Loud Mouth II mufflers sold separately.
