Yep...soon the turbo guys will come in and say if you have a properly sized turbo the spool is almost instant. Well ive had both and "instant" and "almost instant" is the difference between "this is awesome" and "yea its alright". They are right, to a point, but any turbo with that kind of responsiveness will choke very quickly. Thats just how the physics work out.

What size motor are you going to be running? I don't really think you can go to big of an exhaust with a turbo so 3.5" will be fine. Check Craigslist for factory duramax exhaust systems because they are cheap (just swap the muffler out). It's a straight shot back from the tail pipe to the down pipe, but if you go SC you could hook it up to a Y-pipe as well.

We are building a 6.2 set up right now. Customers require fast spool and has no plans to go into the engine. We are doing a 72mm bb. But he is using a STOCK engine. If you are going to add a bigger cam, do a 76MM BB.
That will get you to 700HP to the ground. Be able to pull and still have fun.
If you are looking at buying a blower, headers, and a new cat back. Then change it later, you will be selling the blower and the headers, the cat back you can work around. or sell it and buy a cheaper diesel exhaust.
