Twin Pipe back box exhaust for my S4

[holywood3645]

I have a stainless steel later elan sprint single pipe back box on my car and would prefer the original S4 twin pipe style.
Does anyone have on lying around that they would like to sell or exchange?
Any recommendations on GOOD tight Fitting aftermarket unit.

Thanks
