    you can get the light mapped out

    only other problem your have is the MOT. unless you have a friend in a garage or keep your old cat and swap back before the mot is due

    Thank you for the fast reply, right yeah they make me a custom de-cat pipe n put new flanges ect.. on old ones so it can be refitted by myself before MOT's I understand they don't make much performance diffrence I just hear they give a nicer sound is this true do you know?

    I love me Audi s3 it's just they don't sound mean for the power they are really. I want it sounding a bit meaner n like it eats the road lol.

    Thanks again for the reply!

    If you really want a meaner sound, get a downpipe and decat from either pipeworx or xspower. Making a decat for the standard twin downpipe design is pointless and a waste of time, I don't think you'd be overly impressed with it. A proper 3 inch downpipe and decat you will

    Pm Sam Bryant on here, he got me my downpipe and sportcat sorted cheaper then anywhere else and rapid postage from USA!

    I think he's on at min on thread tt180 post downpipe Decat.

    And YouTube the noise, I agree as above you need both downpipe and Decat or sport cat for better sound.

    Cheers, Sean
