Guys don't worry one bit about that rust you're seeing. It's clearly 409 grade stainless because (a) it's an inexpensive system and (b) 409 will almost immediately form that thin layer of surface rust to protect itself from further corrosion. A lot of OEM exhausts are made out of 409 for these reasons. One reason you pay more for Corsa is because they use 304 stainless which is a higher grade and will look almost brand new for years even in the salt belt.
