I've been looking for this exhaust for almost 5 days and so far I spoke to about 40 dealers and nobody had it in stock.
Luckily, Greddy had 1pc in stock for retail sale but it was for $990.
Compare to other dealers selling it for around $850?
Well worth it because it's been back ordered so either I get one for $990 straight from Greddy or wait until mid December. (not sure)

 

Look in the classifieds. Might get a used one in great condition and for a lot less.
