    03 Mustang gt exhaust

    Okay so my girlfriend has a 03 mustang gt (yeah she had it before i was with her). She has the magnaflow true dual exhaust on it. I thought it was a bit quiet so i got under it to look to see how it was setup and i saw there was FOUR catalytic converters! 2 on each pipe! Is this normal? I know nothing about mustangs.

    And god forbid i try to find it online, ive looked for hours and its hard to find out anything about mustangs because the web is overloaded with 3.8l bs!
