Since no one from the company wanted to answer my Q on the GB thread, I figured I would ask out here!!!! What is it made of? Cat core?

16 gauge T304 Stainless steel piping , stainless steel cat w/ ceramic core and monolitic honeycomb catalyst for maximum flow , stainless steel turbo flex with interlocking stainless steel liner flex pipe ( Inner braid lining ones are very bad for turbo use, they dotn last )

there you go

What are they coated with?Mine came last week.

High Temp paint
