Does anyone know the difference between the Ford Racing M-5230-S, the M-5230-SGT, and the M-5230-5GT? Which has better sound quality? Which is the loudest? Which one should I put on my 09 GT 500? I prefer louder but not cackling!
What kind of exhaust should I put on my GT 500? I put a ford racing power pack on which came with different mufflers and it still isn't loud enough! I don't want to keep buying different mufflers and experimenting.
