Has anyone have had any rusting problems with any of OEM or aftermarket parts for their S? My HKS cat-back suffers from minor rusting problems as well as my HKS wastegate. My OEM header suffered the same. I've checked out a few other Sz around and they don't seem to have any rusts on any parts. I was wondering if this is a problem that I'm suffering (maybe my location have to do with something???) Anyone have any part of their S (under or inside of engine bay) rusting?
