Mandrel Bent Headpipes

Thanks for all the advice! I have the Accurate head pipes and intermediate to the stock mufflers on the car now and they have a small diameter buy the bar and stater. I know the worst restriction is the manifolds and headers would solve all the problems as far as flow, but create other ones. I like the ground clearance and even the look of the manifolds. Plus they are already paid for. I guess I'll try someone local to bend them for me.

I'm trying to get my car to run in the mid to low 13's without using headers and keeping the stock look. I haven't ran it yet but I can tell it's not even close to that.
