I have one which I took off my car after 400 miles so it is like brand new. 
  
Why would you want the most restrictive part of the OEM zorst system. 
  
OH! and I am not local

Got a nismo zorst and hi flow cats and Y-pipe keeps blowing.. its 2nd one ive gone thru - i seem to be the only one whos experiencing this in UK..im thinking maybe just put back the original rigid stock Y pipe 
  
I think if poss anyone local i can just come by and pick up.. posting that heavy lump wud cost a fortune.. 
  
thanks
