SLP's F-Body cat-backs have always been the best performing exhaust systems in the business. Now they're the most versatile, too! Using the industry-exclusive modular design architecture, SLP 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 muffler, the F-Body Loud Mouth II™ system is compatible with our original Loud Mouth™ resonator (#31066). Get both for complete control over your car's sound and performance characteristics.
