ah, the 2 turbos are sequential. I was wondering why you had such big turbos if you were looking for quick spool time. Even the Alpina B10 biturbo used only 2 T25's. For cost reasons, I am going with 1 garrett T3 on my M20 525. I hope to install soon. Still trying to find the best way to mount the IC though. some pics of your setup would be wonderful for reference. :o)
I don't think you will have any problems with excess back pressure. I plan on running everything through the stock exhaust at first. (increasing the throughput is just a question of velocity). the output from my turbo is just a single 2.5 inch pipe anyway.

how did you do the exhaust down pipes? the 2 turbos dumping back into one pipe then splitting for the 2 pipes back?

well I got a good deal, on the turbos brand new,
yes there are alot of things that we could have done but then me and my friend are not normal.
we preferred 2 2.5 exhausts because it is a sequential set up no room under for 2 3.0 pipes under the car. This is a stock motor, with just over 101,000 miles, we decided to keep the stock chip and next we will dyno tune the car for finer running.
