Free-flowing Exhaust Systems may maximize peak horsepower; this is typically accomplished by making the path as straight as possible, using a consistent diameter throughout the system and eliminating obstacles such as Catalytic Converters and pre-catalytic converters or by replacing the Muffler with a less restrictive (and usually louder) one.
In a normally-aspirated engine, this often results in a loss of back pressure which may negatively affect low-end torque.
Forced Induction Engines are not as susceptible to this side effect.
