I haven't picked up any of this stuff yet. This is my prelim shopping list. I am planning on ordering all this stuff through SS @ Gwinnett, unless I am able to find all of it much cheaper elsewhere. If not, I rather not have to hassle with it and plus it would all be at the service dept ready for install.
The nasty thing about going to the 3" is having to do the deletes and the associated labor cost of removing the intake manifold. I do hear that you pickup a bit more top end and the spool is a couple of hundred rpms sooner.
