I finally got the exhaust finished today. I'm pretty happy with the way it came out. I still need to add two double slip joints in between the cylinder banks, some wastegate dump supports, and a couple of O2 bungs, but other than that, it's done. This first system is only 304 SS but I made sure to carefully purge everything, and all of the welds are full penetration welds rather than the standard "automotive style" welds so it will have the best possible chance of surviving. Also, the turbo is supported by a 1/4" thick plate bracket so the actual exhaust tubing isn't holding any weight other than it's own. If the 304 doesn't survive, then I will do the second set in 321 and see how long that lasts.

That exhaust work is mighty fine, but it won't pass CA or TX emissions, will it?

Absolutely not. This is the ''race version'' not the ''street version'' because the test car will be a track car.

Holy mother....

First off, isn't that a bit far for exhaust to travel prior to hitting the turbo? Maybe it's just the pictures.

The exhaust exit from that turbo is amazing. It's going to be insane.....

Im guessing the oil filter is going to be relocated due to space and heat?

Yes sir. Probably relocate it to the bulkhead on the passenger side, and add an Accusump at the same time.

It shouldn't be too bad and in reality, it's not much further than the aftermarket Subie equal length headers once you factor in the up-pipe. Plus, that's where Porsche put the turbos in the 917/30. There's really no other place within the chassis to put it and keep the heat away from plastic, rubber or fluid lines.

kcpaz; it looks like a wild and well planned system..!
Are you planning to get some insulation (or heat shield) between the tubes and gearbox to help keeping the heat away?
