I'm planning to mount the cutout right before the rear axle. How much low end torque should I expect to lose? There would be less backpressure right?

Can the cutout be installed in such a way to point it down while still keeping stock ground clearance? If not does anyone sell a cutout with a mini donkey dong attached to it?

BTW, I'm planning on an electric cutout.

 

Your not losing any torque. You could turn the cutout part down, but your going to lose that much clearance. Or you could run it sideways with a turndown, but the exhaust is still going to go back regardless

 

I'm more worried about the floor of the car heating up.

 

It would just be in the back hatch, if it heats up any at all. It's not going to be any hotter then without the cutout, the exhaust isnt going to be batting the floorboard at all.
