Like probably a hundred other people on here, I've just bought the new XS Power 3" downpipe and cat. It all looks spot on, well done Welly for all the perseverance, you're a legend for getting that sorted! So from what I've read on fitting one on an S3, there's the hard way (removing the head) or the harder way (not removing the head), neither of which sound too appetizing but I'm potentially willing to give it a go (never done any engine work before). What I'm hoping for is a text book Audi-Sport fitting guide with step by step fool proof instructions for the below-average modder. Is it worth getting my hands dirty on this or am I going to screw up, not fit the cambelt properly and destroy my car? More than happy to cut the old downpipe out if that makes it easier, but I am doing this on my drive so only have drive on ramps. Any help/suggestions would be much appreciated!
