Prices for pre- and rear silencer series Quattro NG Type89

Hi meal, have me for my 90s Quattro with NG machine times prices for pre- and final silencer. According to the workshop should cost the ESD 393 EUR and the VSD 247 EUR. Are these still very dense at AUDI????? For the price I get at FOX in VA a group A system from KAT (VSD 200 EUR, ESD 450 EUR). ESD ́s from Supersport or Jetex in VA cost only 350 EUR and new retrofit parts in original quality are thus at 200 EUR, with EBAY stood already ESD ́s for 89 EUR and VSD ́s for 33 I’m now thinking about what to do. The car is running again after the repair and if that stays like this – will watch it – then it is still made TÜV-finished, i.e. new exhaust system. But will also be asked in parallel with a vehicle recycler here with us. Maybe he still has a reasonably intact car standing around or his AGA. So, what do you mean at the prices? What irritates me is that I was looking for parts with the Ertaz in the small talk about the AGA and he looked at the ETKA and stood for the ESD 229 EUR in it, or did he forget about it?
