    i recently brought a downpipe and decat, it fits all 1.8t engines and s3 engine with adaption to the flange, i was just wondering how easy would this be to fit to a 1.8t quattro? i was going to leave the decat off for now as it needs welding on to where the cat ends and i know nothing about welding. would i be able to fit just the downpipe shiown below or would it all need to be fitted together?

    OK mate, it WILL fit a 1.8T engine with a K03.

    It will NOT fit an S3. No, no, no, no, no.

    That downpipe is for the K03 mate, end of.

    Easy to fit on the K03 turbo to be fair, not a bad job at all. It just bolts on. I believe that downpipe comes with gaskets and everything needed to change.

    yeah ive got a 1.8t quattro but not the s3 its the 180bhp model. so it should fit? but will the downpipe fit on its own like is there a 3 holed bolt flange to connect onto the standard cat? or will i have to add the decat? and have the decat welded on?

    it will in theory fit a 1.8TQ, although you might find it's tight against the prop/transfer housing.

    the whole part below has to be fitted, as the downpipe alone will be well short of your cat back system.
