The Gibson MWA Superflow offset/center oval muffler is a stainless straight‑thru design that prioritizes maximum sound and exceptional flow. With no internal packing or weak baffles, it flows nearly as freely as a straight pipe while keeping interior drone minimal. Low‑profile, non‑directional construction and quality stainless materials deliver an aggressive tone and a lightweight, durable unit made in the USA.
