If you are debating the sidepipes vs. undercar, go with undercar exhaust. I built mine with sidepipes due to peer pressure and hated it from day one. It is nothing for me to drive 400 miles at a time. In traffic with the top up, you will get fumes in the car trapped by the roof. I changed mine to 3" stainless pipe all the way out to the rear, no heat from backpressure, just a nice ride. It is still loud, but it is mostly behind you. I also did not experience any power loss. Go with your instinct!! and enjoy the ride!!!
