Overview

Behind a dual exhaust with two pipes in and two pipes out, this MagnaFlow muffler sets a single oval stainless body across both runs. The listing names the sound as deep signature and sells it as a universal fit for cars and trucks.

MagnaFlow backs the stainless shell with a construction warranty that covers the life of the muffler. The listing contains no description text, no internal design and no vehicle list.

Who it's for

A fabricator or shop building or repairing a dual system can drop this body into the run. Owners of a single exhaust, or anyone who needs a bolt-in part for one named car, should choose a different muffler.
