It was only the rear section plus the Y pipe. Mid pipe is discontinued. Got it from b2autodesign.

Well, it seems that exhaust is in the states and it shipped out today, should be here on Monday. That was fast!

I still don't know what to do for the midpipe. I know of a few custom shops around (they bend, weld and create custom exhaust), but it still takes about 1.5 hours to get there and that's a royal PITA.
I wish i could just buy the piping somewhere that bolts right between the downpipes and the rear section. Any suggestions?

You could buy that car treats midpipe that's for sale on eBay. It resembles the HKS midpipe, i think several members have purchased it......it deletes the secondary cats as well!! Congrats on your exhaust being in the US, that's awesome!!

i'm concerned about drone and while the HKS system has 0 drone, the fact that car treats' midpipe deletes the resonator and secondary catalytic converters concerns me.

I believe that the now discontinued HKS midpipe had a resonator, right?

Yes the HKS has the rear resonator, it's a bit smaller than the OEM resonator.....

Lobuxracer has there comments concerning that product:

Add to this the "49 State emissions legal" and we've got straight up fraud. It is illegal to remove a working catalytic converter from any emissions controlled vehicle in all 50 states according to the EPA. It doesn't mean you can't do it and get away with it, but to claim this product is emissions legal couldn't be a more bald faced lie.

If it were my decision, I'd pick something else. Custom made might be better, but it might also be worse. It all depends on who is doing the work and where they're getting their materials. Burns Stainless makes some of the best collectors and X pipes out there. If a shop is using Burns, they're concerned about quality and will likely do excellent work (no guarantees, but at least they're starting with good stuff).
Their web site is here:

As I have previously said, modify the stock mod pipe or have one fabricated by a good good muffler shop that can mandrel bend and has the ability to do decent welding. Also look into the 2 into one Burns merges that Lobux recommends.
