This is what I did.
I started with a small kind of like half circle cut and slowly went larger.
I used a small pneumatic airsaw. (Pick `em up at Harbor Freight)
The gelcoat on the A&C bodies is pretty thick and durable.
Cut a little, bolt on the sidepipes.
Remove sidepipes. Cut a little.
Lather rinse repeat.
Once you`re satisfied with your cut and pipe to body gap, Harbor Freight also sells sanding drums that you put on your cordless drill. (doesn`t spin as fast as a dremel and allows you to fine sand any awkward cuts.

I think I left a half-inch gap between the pipes and the top of the cutout in the body. (allowing room for the motor to torque on revs)

Also, anytime your cutting fiberglass, wear a dust mask.

Oh, one last thing, if your cuts aren`t as exactly super precise to the tenth of an angle, don`t sweat it.
That cutout is the lowest point on your car. Plus with the pipes exiting the body, nobody will notice.
