Im seriously considering buying some BBK long tubes.... im cheap to say the least and could care less what anyone else thinks. A good example is my exhaust that I chopped off just before the rear axle and turned the ends down with 30* bends. I care about power, to hell with the rest. So, Im thinking about dropping out the whole exhaust, putting in the BBK long tubes and then welding new straight exhaust pipes back to my axles and dumping them like before. This would totally eliminate the X pipe and cats, I live in FL so no emissions testing here. My question is, am I going to actually loose power doing this? Im pretty sure that having some back pressure is a good thing but how much? Would the x pipe be the way to create this pressure?
