GIBSON SUPERFLOW™ ROUND CENTER IN/CENTER OUT HIGH-PERFORMANCE MUFFLERS

SuperFlow™ muffler delivers more power, torque and the Gibson "big block" sound at the tailpipe! Straight-through design and all-welded construction delivering maximum flow and increased power for improved low- and mid-range performance Baffled and chambered for better volume efficiency and unrestricted flow; never packed or screened and with nothing to blow out Extra-thick muffler case and heavy-gauge tubing help keep noise contained within the system, not in the cab! SuperFlow™ mufflers deliver, on average, a 30% improvement in flow and restriction than stock mufflers. Limited lifetime warranty.
