Don't bother with Toyosports they have all there parts imported from china, and unless you like very poor customer service avoid like the plague.
I got mine from Turbo-revs on ebay the guy is much more helpful and the downpipes are better quality than the toyosports one.
If you want one with a cat in there was a manufacturer on Piston-heads selling the much cheaper than Miltek.
I will try and find the link.

http://www.jaex.co.uk/Sure it was this place that was offering them custom built to you spec
Around £200 for a de-cat and £300 for a 200cel cat version.
