Cant Decide which one to get. The Magnafolw comes with the cat-back pipes that are 3" vs the borla still runs a 2.5". Anyone done one of these on the GT500 yet. Dont want a loud exhaust just looking for a deep mellow sound. Also does anyone know if a bassani x pipe off of a 05 mustang will work on these cars. I have one just laying aroung collecting dust. Thanks for your input.
