Open up the Exhaust to 2 1/2" all the way back including the 2 1/8" choke flange behind the CAT. Add a free flowing 2 1/2" muffler,your stock turbo will boost better and the back pressure will be 0.0PSI. When I was running my tests on back pressure, I got readings as high as 5 PSI with a stock muffler. At first GDE was pushed their turbo kit using the stock exhaust, but one guy I know of who went with it, opened up his exhaust, and got even more boost, than they advertise, DUHHHHH! I haven't heard any more stock exhaust recommendations any more.

May Sir Isac Newton rest in peace, open up your exhaust to get the boost you want.
