| 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 our industry-exclusive modular design architecture, 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 muffler, the F-Body Loud Mouth system is compatible with our original Loud Mouth II bullet-type race muffler (#31067). Get both for complete control over your car’s sound and performance characteristics.
NOTES: Includes Loud Mouth resonator. Loud Mouth II race mufflers sold separately.
