You dont need to worry about the turbo side as that doesnt leak 99% of the time, but if you want to get rid of that, you should get a k03 silencer removal kit from ebay/aliexpress. I got mine from ali from a firm called Volm. Fitting was perfect, seal was perfect. worked with the oem discharge pipe. I got a k04 version but there's a ko3 version too.
As for the intercooler side, yes that's an option. Cut down the quick connect housing, measure your discharge pipe to intercooler rubber hose diameter and get someone to weld you an aluminium extension of the same or slightly smaller diameter. If possible, get them to do a dent in it, so the collar has something to grip so it doesnt just slide off.
Note: Tried adding images to post but they dont seem to be uploading. I've included imgur links instead.
