The Gibson CFT Superflow muffler integrates chambered resonance and louvered tuning to manage exhaust velocity and tone, delivering a deeper sound while maintaining flow. This dual/dual oval 4x9x18in model with 3in inlet/outlet is fully welded stainless and non‑packed to avoid long‑term sound loss. The reversible layout and louvered internals are built for efficiency and durable operation under repeated use.
