We are located in the wonderful heartland of america :) Wisconsin, roughly 20 minutes outside milwaukee metro area. The manifold would be most likely the most expensive part since it would be a tubular equal length made of schedule 40 stainless steel, roughly unbreakable :) Manifolds usually go for i believe 800 with that setup. I imagine if I sat down and made up a jig to make a log style manifold it would be much, much cheaper but not flow nearly enough. Downpipes including flex sections on average are 350 made of mandrel bent stainless steel. I believe the rest of the exhaust made of stainless mandrel with no welds or anything since its from the bender would be 750 including the high flow cat and and a thermal muffler. I believe the Fmic kit would most likely go for 750 with what ever flange for a bov you wanted. Intercooler kits would use a 450 cfm garret core, unless you wanted a larger one, full 2.5" piping, all T-bolt clamps and silicone adaptor hoses. Piping would be polished stainless for that oh so nice chrome look. If some one was very serious about a full setup, I could probably fabricate their full kit on my car and then ship it out, with a full manifold, turbo, all oil lines, water lines, gaskets, downpipe and exhaust, intake pipe, and a front mount kit. Basically you get a giant box and it all bolts right on. I need more people to post on here before I go ahead and make the jig for this roughly the response from 20 or more people would be enough and we are at 9 right now I believe and its only been a day:) So please let other people know from other forums with these cars as to what I am looking to do.
