Power vault 1 catback

I have the power vault 1 catback on my VX and the front of the muffler rusted out. Does anyone have any ideas what to replace it with? And what are the inlet and outlet sizes? I just need a muffler the other pipes are good.
The power vault is 19" long.
Thanks Steve

i think magnaflow makes an 18" glasspack thats similar to the pv

Does anyone know what are the inlet and outlet sizes of the Power Vault 1?

I'd Guess 2.5 or 2.25... but Don't know for certain. An Aero Turbine is a good substitute though.
