The Gibson CFT Superflow stainless muffler is a chambered oval unit that tunes exhaust flow to deliver a deeper tone and improved throttle response. This Offset/Offset 4x9x18 inch body uses 2.25 inch inlet and outlet plumbing. Its chambered, louvered core and directional ports draw and expel gases at higher velocity; non‑packed, fully welded internal construction avoids sound degradation while promoting maximum flow and increased power.
