just fitted supersprint back box

  1. #1
    just fitted my supersprint back box

    yet to fit the manifold and centre pipe

    got the manifold but not got the centre pipe yet


    i started the car after i fitted the supersprint rear box and its VERY quiet?

    is that because its still got the cat in place and now a straight through pipe?

    or because i havent fitted my 4-2-1 manifold yet?

    It'll be quiet untill you give it some beans on a open country road.

    yeah but i just gave it a few revs and it still doesnt seem loud

    but like i said its running standard manifold with cat and standard centre pipe

    break it in a little. have you driven it yet though or just sat at idle?

    is it a race bbox or a road setup?

    i just left it at idle as the car is off the road at the moment

    i think its the race one not too sure??

    Yeah its the race one, dont worry it will get louder, mine took about 3-4 days of driving till mine got properly loud and with a 4-2-1 mani and centre section it makes it raspy and loud and fook when hard accelerating, have fun

    The standard centre pipe has a silencer in it, it wont be loud untill you get rid of the standard pipe.

    It doesn't sound loud at all tho Desmo... I recon it's as loud as a standard box! lol

    Thats because the bore of the exhaust is only 50mm, a big 100mm one like a sportex is a bit like an amplifier. Remember group n exhausts cant be louder than 98db, basically its not designed to make it louder. The race race section is the bit that makes it loud

    does it sound different at all tho?

    as said its a little like a standard exhaust at the mo lol but as stated its brand new so needs to be worn in

    will be getting the race section for it aswell tho and i got a 4-2-1 manifold to fit
