I just took off the stock rear bumper and that weighs as much as a 3x3 filled with concrete, so I would still be lighter than stock anyway lol..
As or the exhaust, I'm not above sectioning the floor a bit to make exhaust fit better... I am going to cut out the majority of the rear lower inner quarter panel and section that for a thinner profile so the tailpipes can exit right at the back.
I have used the stainless band clamps in the past and they work nice as a way to make the exhaust removable in case of trans work etc.
