Close to 700 hp and have ran a 3 1/2" side exit exhaust forever and never a problem w/the police not even w/slicks on the street.............They are a bit loud but I don't buy the idea that small pipes make hp in a big motor, just not true and I know of a few 8 second and quicker NOS cars w/some BIG exhaust........... beer
