No way an SS cat-back system should cost you that. They obviously don't want the work or think you're a moron. Either look for a Cybox/Ragazzon system or keep shopping around at local exhaust places. Even here in Australia where we pay more for everything I have been quoted ~320GBP to get a full cat-back S/S system and would suggest you should be able to get a similar quote over there somewhere.
Though one tip, make sure you mention you want a straight through with only 1 or 2 silencers. Most of these places quoting those absurd prices are probably factoring in replacing all 3/4 silencers on the OEM setup! VERY expensive! So get a straight through with a decent sized central silencer and maybe a small rear silencer. Should get a cheaper quote!
