An off-road exhaust skips the muffler for maximum flow and the loudest sound, with a turn-down exit that angles toward the ground instead of a bumper-mounted tip.
why this one — MagnaFlow's muffler-delete Off Road Pro Series for first-gen (2011-2014) 3.5L trucks, for the loudest, least-restricted sound.
No manufacturer or independent dyno figure found for this specific product. Cat-backs on turbo trucks with a downpipe/tune doing the real work typically carry no standalone gain claim; sound/tone is the primary value prop.
