Based on my results I would say NO !
I think that the stock exhaust would show even better torque band due to the engine wanting a lower vtech point.
My exhaust is very close to oem the difference being in 3mm difference of diameter.

I think John_Z has dyno's before and after he's now running OEM with better results than the single he had before. I think it was the 70mm.

Yeah, hopefully switching to the 2.5" at the split didn't hurt too much. It's definitely a lot quieter (which was my goal). Bisi said that it's almost like my previous "true" 3" exhaust but with longer piping. Which may lead to running a little richer. I'd still be happy at 490ish rwhp if I should lose some. 
At least for now. After switching out the HG, I'm going in for the speed/psi tune.

honestly i hate stock exhaust.
heavy and don't look good, especially i have full j's racing cf body kit, so the rear bumper it's kinda high, and u can see the whole muffler , so ewwwww..
but i just gave my tuner a PM about this, i hope he PM me back of what he knows..

Interesting!
I am running a supercharger
I recently switched from asm 70mm single to amuse 70mm->50mm split dual
I noticed a midrange gain with my butt dyno... I thought it was just my imagination till I saw this thread!
