2006 apex exhaust material

[Chudwick]

Hey guys, I swapped an apex engine into a rzr and it fired right up. Next up is the exhaust and I want to reuse the flex pipes that came stock on the sled. It only had 600 miles so they’re pretty much brand new. I think I read somewhere that the stock exhaust on these might be titanium or some funky alloy. Does anybody know for sure what kind of metal these are ?

The flex pipes are a low grade stainless. Header pipes, if original were titanium.
