Do you mean "back pressure?"

For naturally aspirated cars, a little back pressure is good. On cars with forced induction (ie. turbo), less is better.

Actually both NA and Force Induction Vehicle need "some" back pressure,
in general, the less Back pressure, the more top-end Horse Power, the more backpressure, the more low-mid range torque..
but it all depends on the setup..

backpressure is the pressure that builds up when your exhaust fumes don't exit your exhaust system fast enough. Basically the more backpressure you have the better torque you have the less backpressure the more horsepower. However too much backpressure is bad
