I got a call yesterday as well and a charge to my CC. I should have mine by Friday or Monday.
Interesting that none of the exhaust components are on his website anymore, only the header is on there. Guess he took the front section, mid-pipe and muffler off as this is it.

Got it today. Looks like an RB flange, (2) 2" OD pipes into a 3" OD pipe into a 4" bullet type muffler, 4" outlet into a 3" OD pipe.
I'm going to dyno again in January, should be able to compare numbers since my last dyno was just a few months ago. Only other change besides this exhaust section since last dyno is an AWR 3.5" intake tube from TB to AFM. I'm hoping to see at least a 2+ rwhp gain on the dyno for these mods.

I just installed the midpipe today with 3" after it to a magnaflow. it's so damn loud I'm going to try and shove a silencer in there somewhere. LOL! But it pulls much much harder above 5k! I need a new tranny cause my power band is from 5k to 8k now and 2nd gear shift into 3rd puts me at 6k. lol!

Your power band really should be about 6-8k+. Put Miata gears in the RX-7 box. That is the 2nd best thing I ever did, the best being a 5.12 R&P.

The complete ISC setup is supposed to be hands down the best exhaust system. This is what I have been told and read from many of the top cars who have tried several systems.
I have recently learned that the ISC header is the same as the Mazdaspeed header, the only difference being the ISC one is stainless. I've got the Mazdaspeed header and the rest of the ISC exhaust now. Going to the dyno in about 2 weeks...
