Ok, so today we took off the old exhaust and downpipe and fitted the new one and also fitted the piping for the intercooler.
The hardest part was getting all the heat shields off so that we could get the down pipe off. Once done, it was farly easy to remove the very heavy downpipe.
The new stuff went on very easily, and we had to fabricate a bracket to attach the back box... this will be fitted on monday.
