i have an 06 f4i with factory pipe.ill be buying a new pipe one day but i want it louder. whats the best way to knock out the baffle in my stock pipe so it will be louder. my friend bought a f4 with this done and it dont sound too bad.i was just going to stick something down in there and start knocking but i wasnt sure about getting the baffle wedged sideways and restricting the airflow
any suggestions..........
