Back in the day, before the EPA, Ralph Nader and the Sierra Club neutered street performance, the big–block V8 reigned supreme. On streets, strips and tracks, the unmistakable rumble and otherworldly power found its way to many a winner's circle. And now, you can get that classic power and sound back, thanks to Gibson SFT Round Superflow Mufflers.

Just like the big–blocks from the classic muscle car era, Gibson SFT Round Superflow Mufflers are all about low– to mid–range performance. That means tire–turning torque off the line and headlight–sucking passing power when you need it. The secret is in reversed tuning ports and pressurized chambers that maximize exhaust flow and scavenging. And, with this outrageous performance bite, Gibson's chambered and louvered internal design barks with the big V8 growl.

Gibson gives you a wide selection of inlet and outlet sizes, plus your choice of single or dual outputs. Choose aluminized steel for a wallet–friendly wallop or T304 stainless if you want some shwing with your performance. Even better, Gibson crafts your SFT Round Superflow Mufflers in the USA and backs ‘em with a Lifetime Warranty.

This was replacement muffler for catback system bought 4 years ago. The inlet pipe of muffler rusted out after so required replacement. Muffler is well built and has good throaty sound at idle and under load but is more mellow at cruise.

Great muffler. I was tired of the louder flow through muffler I had before. This one is 25% over stock. Still delivers all the HP and TQ like a Maggy with half the sound. If your tired of waking the neighbors this is the one for you. Delivered in 3 days awesome service..

Too Quiet

I bought this muffler expecting it to be deeper and louder than my stock muffler, but it was only barely. Definitely not worth the money.
