from memory adam paid a little less than paid for my powercraft 4-1...but got a complete exhaust system...headers thru to tip...not just a straight thru system either
one thing to consider for the 7a build is that due to the extra height of the block you will more than likely encounter the problem of off the shelf headers like powercraft/toda fouling on the firewall/underside...so you need to factor a way around this into the planning...
personally i went for cusco rubbers/sptech lowered mounts (same as tecarts) and converted to a ae101 sump/windage tray for more clearance"shouldnt" have any problems now
anyways...another excuse to post a pic of the powercraft headers
