I don't want to step on any toes, but my straight honest answer is no. I'm on stock up pipes, Profab downpipe and egr delete pipe, I cut and welded a cap on my stock uppipe for the delete, I have a 4" exhaust with resonator AND muffler with stock manifold, and a Danville charger. I'm over 600hp and limited by fuel, not air and not exhaust; and that's still holding over 25k rail in attempts to keep it "safe". If I add more fuel, I'll need to add engine mods - no thanks! If I were you, I'd forget the expensive uppipes, the manifold, etc ... and look for a used (or new) 66 or 68mm Danville stg2r and let it eat. You don't even truly need larger tips. Rancelot is making around the same power as me on stock sticks. I just came across a nice deal and enjoy less timing and pulse width. And yes, I just did the tips. Good luck.
