but since the shop is doin it, I'd def pick one up, assuming the design you used on his 9 would fit most mildly modded 8's?

Yes and no. Currently in a normal 02 housing that is not dumped, whether it be stock or Ebay, the wastegate exhaust is being dumped in a turbulent spot, inches after the turbine's exhaust. Re-routing it so it would dump it further down could help, but the most gains will be seen by having it dump to the atmosphere.
I dont think you realize how loud your car already is at full throttle with a 3" exhaust. The extra noise this provides isnt earth shattering and it only makes the noise at WOT. I have bunch of vids of my car racing and stuff with the dump

I would like tio explore the option of attaching a silencer from a Porsche 930 Turbo. Those cars have a small muffler like silincer on the dump tubes.
What we need next is a genuine A - B test to quantify exactly what gains are made (if any) with just the externally dumping tube from the 02 housing

At that point we can start to produce them
One car on the dyno without an A - B test is not enough data for me to get overly excited
At this point its just a curious example

I think what we are going to do is offer them on a custom basis untill we can verify that it is in fact making additional power
At that point we can start to produce them

Let me know if you need a test mule!
how much will it cost to do a custom external dump tube.
