Gibson Exhaust 55143S CFT Superflow Oval Offset/Center Muffler Stainless Steel

The Gibson Performance 55143S CFT Superflow Muffler is a high-performance stainless steel muffler engineered with Gibson's proprietary Convergent Flow Technology (CFT). Unlike conventional mufflers, the CFT Superflow actively tunes your exhaust by combining resonance chambers, directional louvered tuning ports, and angular induction to draw exhaust gases in and expel them at a higher velocity — resulting in increased power output and a deep, aggressive exhaust tone.

Key Features:

• Convergent Flow Technology (CFT): Resonance chambers and directional louvered tuning ports work together to optimize exhaust flow and boost performance
• Chambered and Louvered Core: No packing, no baffles, and no weak deflectors — eliminates sound degradation over time
• Non-Packed Construction: Maintains consistent, deep sound quality throughout the life of the muffler
• Fully Welded Solid Internal Construction: Built for long-lasting durability and structural integrity
• Deep Powerful Tone: Produces a performance exhaust note with minimal interior drone
• Reversible Design: Flexible installation orientation for easier fitment
• Oval Body — 4 x 9 x 13 in.: Offset inlet / Center outlet configuration
• Stainless Steel Construction: Corrosion-resistant finish with lifetime warranty coverage against internal rust-through
• 50-State Legal: No emissions certification (EO) required; legal for sale and use in all 50 states

The Gibson CFT Superflow 55143S is a straightforward, high-impact upgrade over restrictive factory mufflers. Its packerless, baffleless design means performance and sound quality that won't fade over time, backed by Gibson's commitment to quality stainless steel construction.
