Anyone have a Corsa WAV for 2500HD

[mtnman2k1]

I was wondering if anyone has a WAV or can make a WAV for the corsa cat-back on a 2500 HD CC 6.0 with everything else stock (no headers, removed or upgraded cats,..etc). I know the corsa site has a wav for the GMC Yukon Denali, but I'm sure the sound would be different due to the different setups (longer plumbing on the 2500HD CC, slightly different engines).

I have been waiting for one to come out for my truck but nothing yet. Wonder what makes it 03-04 only???
