The OEM over axle pipe on the 2011-2014 Mustang V8 leaves a lot to be desired. The stock unit is manufactured with the goal of suppressing the motors sound as much as possible. This sound deadening robs the motor of vital flow and horsepower. Take your horsepower back with the Lethal Performance Over Axel Pipes.
The Lethal Performance Over Axle Pipes are made from T304 stainless steel and connect your OEM or aftermarket Axle Back Exhaust system that uses stock connections.
