Product Description

Gibson's SFT Superflow uses a baffled, chambered design instead of packed fiber or a screen, delivering an aggressive "big block" exterior tone while keeping cab interior noise noticeably lower than comparable aftermarket mufflers. Because nothing inside can pack down or blow out, the sound and flow characteristics stay consistent over the muffler's life.

Built entirely from welded stainless steel and backed by Gibson's lifetime rust-through warranty, it's a solid pick for big block engines running catalytic converters - but note the warranty is voided by off-road/racing use or forced-induction/nitrous setups not equipped from the factory.
