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, we've 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, re-tighten, and you're done. No other cat-back offers this level of performance and adaptability!

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

NOTES: Includes SLP race mufflers. SLP resonators (#31062) sold separately.
