I have added several performance modz... to my 2000 Honda Civic EX, nothing doing with the exaust system (headers, cat. converter, pipes, muffler)... my car roarz loud... like it has a good exhaust system... but it doesn't it has that stock pipe thatz opening iz a about 1" 1/4... and I'm wondering if that loud sound iz all the pressure being forced out the cheap ass stock muffler... can not changing exhaust components... weaken the TOP SPEED my car will get from these modz... acceleration does well.. but TOP SPEED doesn't really change... could it be pressuring building up at a certain speed that it can't acheive higher speedz because the pressure build up in the exhaust chamberz or what?.... help me out here on the importance of the exhaust system
