A high performance muffler has to give you more usable power, great sound, and last. Sounds simple, right? Yet there are so many on the market that don’t deliver. The power is too high in the rpm range to be usable, the exhaust noise resonates throughout the cab, or the muffler rots out in a few years. If you want a muffler that exceeds the performance advantages provided by all other mufflers on the market, get a Gibson Superflow Muffler with Suspended Flow Technology (SFT).
The all-welded construction SFT Superflow muffler is baffled and chambered for better volume efficiency with unrestricted flow. The straight-through design provides maximum flow for increased usable horsepower and torque. The SFT Superflow is so efficient it has only 5% exhaust flow restriction, as opposed to the 34% or more restriction in a typical stock muffler, and the 10-20% restriction that exists with some aftermarket mufflers.
With a SFT Superflow muffler you get powerful “big block” sound at the tailpipe without a lot of resonance in the cab. And the increased flow and great sound is achieved without using any muffler packing, so there’s no packing to blow out. Your exhaust flow and sound will remain consistent throughout the life of the muffler.
SFT Superflow aluminized mufflers are made of heavy duty gauge steel for extended durability and longer life. Stainless steel SFT Superflow mufflers are constructed from aircraft grade T304 stainless, for optimum appearance and corrosion resistance. Aluminized mufflers are warranted against defects in materials and workmanship, but not rust through, for as long as the original purchaser owns the vehicle on which the muffler is installed. Stainless steel mufflers are warranted against defects in materials and workmanship, including rust through, for as long as the original purchaser owns the vehicle on which the muffler is installed.
Gibson SFT Superflow mufflers are manufactured in the USA.
