I actually got mine done at Kwik Fit! I assumed it was the same as the Brit version so booked it in as that, I didn't realise it went up and over the 4WS kit. They spotted it straight away and tracked a proper one down. They had to get a genuine Toyota one sent over from Japan but it only took them a week and just(?) ?60 more than their pattern version of the pipe for the Brit spec car. About ?240 for the middle and rear sections, fitted. That was a couple of years ago now though. I suspect it depends how helpful the guy who serves you wants to be. This was the Four Lane Ends branch in Newcastle.   Hope this helps. Dave.    

thinking about it i got a local tyre and exhaust firm to do me a quote for a replacement standard exhaust for my st203 but it came to like £600 or something crazy like that but that was the whole system if it's only a section of the exhaust then it shouldn't be to bad keep the cat if poss

Cheers for the help, I got a quote from powerflow for a custom exhaust and they quoted 460 for a complete system (which is what I need) but being a student I didn't really want to spend that much. Managed to track a 4ws being broken for parts on ebay and got one in good condition for cheap. thanks for the help though!
