2 1/2" pipes in stainless.
The cats are Magnaflow.
The mufflers are Dynomax VT. They have a flapper valve in them so at low throttle they are nice and quiet and whey you give it a bootfull they open up and really roar.
They work similar to the variable mufflers fitted to HSV GTS's although they are electronically controlled on the HSV's.
I will do the tailpipes when i get the final ride height sorted. After that i will pull the whole system off and paint it.
