I was wondering if it's ok to drive my car normally if I'm going to put a downpipe with sports cat and cat back exhaust (i.e. turbo-back) to my car without exhaust specific map? Does the engine run on lean mixture or is there some other things that could go wrong with this setup? I have the 1.8 tfsi engine in my car btw. I'm going to get stage 2 map put on my car later on but it could take a couple of months before I'm going to get it.
