Bob,
Welcome to the Corsa fan club. Any pics of the install?
I share your comments about the sound qualities of the system, relatively quiet drone free when just cruising down the road then full LT5 thunder when you put your foot in it.
In my case I went with 3" to 2.5" stainless reducers from SW to transition from the 3" cat outlet to the 2.5" Corsa tube diameter. Added 4" flexes just after the reducers to help eliminate bending forces in the system. Also used some exhaust pipe sealant in the joints to eliminate any small leaks.
