OEM exhaust design...

Now that I have my stock exhaust off the car I could get a closer look at it. Seems to me the bends are 'kinked' bad (no mandrel bending). Also for those who have switched out their exhaust for an aftermarket system, do you think the lack of heat shields(found on the stock unit) that are not on most aftermarket exhausts, have any adverse effect? What were the heat shields shielding?
