    If your looking to get more power you would be better off with a good remap tested on a dyno dynamics rolling road
    That spending your time and money removing the cat
    Here is a dyno of a e46 320d 150bhp 2003
    ImageUploadedByTapatalk1369092836.854924.jpg
    I remap these from 150bhp to 195-200bhp with 330-340ft of torque

    Dyno lottery all the time i had it done at awesome gti i used to be in the vag scene and it was a rolling road day with other vags and audis and that
    i got 3 runs for £35 quid.
    Best run was 191bhp and 322ft torque
    hopefully with a decat and my new maf i should hit the 200bhp

    To be honest, a pain in the @rse!
    If you have access to a hoist or pit it helps but the nuts that attach the pipe to the manifold are a sod to get to and will be mega tight.
    You will need a good selection of stubby and offset wrenches, sockets, extensions and strong friends!
    Also, have a load of washers available in case the flange on the decat pipe is thinner than on the old exhaust.Mine was.
    Good luck Rich.
