sorry if i have stepped on people toes or people have lost the point im trying to make
is a giant exhaust good for the street? only if we lived in a world where we were all deaf
will a giant exhaust loose you power? only if you motor doesn't have a well designed header/extractor.
i honestly WANT to see a dyno that proves back pressure will show a gain somewhere on some motor
