    for starters you have a **** catback. but still extractors and hi flow cats will improve the note somewhat.

    Yes, extractors and cats will make it more distinct and louder. The bonus is between 20 and 30 kW too.

    I can do 4-1's and high flow metal cats for $1330 shipped. All direct fit including gaskets.

    the middle mufflers on any exhaust these days are a straight through style and changing these will result in no change to exhaust sound, best to do whats mentioned extractors and hiflows

    Also the diference between xforce Medium note and LOUD note is the resi is replaced with one hotdog per exhaust side
