This comes down to the size of the pipe and how much back pressure you lose You may accually lose performance if you have a zero Back pressure system. Are you running dual exhaust out of it? If so just put in a X or H pipe to cure the back pressure problem if it's a single pipe reduce the pipe about a 1/4 in in one section to increase your back pressure just a bit. This should help keep your HP gain where it is at.

the 4.3 needs the back pressure from the cat so that will have to remain in the system. You will gain milage by taking off the muffler and adding a 2nd pipe. I live in indiana and all you are required to have on the exhaust system is a cat so you will not get any fines here. but check your state regulations. but MOST cops dont worry about exhaust. they have more things on there mind, like the guy that just flew past that stop sign over there. I will bet you $500 dollars you will never get stopped even if your regulations forbid it. So do what you want. Good Luck!!

Just put a low restriction muffler on your car. I don't know if you really lose mpg going with straight pipes, but you will help burn the valves. You don't need all the noise violations, let your buddy keep the cops busy. Better him than you.

Gas mileage? None, you should gain a bit. BUT DON'T DRIVE WITH STRAIGHT PIPES ON THE STREET UNLESS YOU WANT TO GET HUGE FINES.
