2006 Accent Atlantic Exhaust alternatives?
 

Hi Guys,
hope someone might be able to help.
My better half drives a 2006 Hyundai Accent Petrol hatchback 1.4 GL FWD III MC 1399cc, 71KW, 97HP, G4EE. Its an auto-box and she loves it, but I'm struggling to find centre and rear silencer boxes for it. I managed to find a front flexi and replaced that as it was badly corroded and blowing, but I noticed the middle and back boxes were getting bad as well. Are there any middle/rear boxes from other models which might fit (maybe even with some modification)?

I'm in the United Kingdom.

Thanks for any suggestions.
