without getting too detailed, for your motor to work efficiently it needs to have some ammount of back pressure (resistance to the exhaust gas flow) present in the exhaust system. usually with a drop in back pressure you get a drop in bottom-end power, and, if done correctly, a gain in top end power. but in this case, a shitty stock AE82 with bugger all back pressure due to being de-mufflered would most likely have less power down low and probably no more up top. and would sound criminally shithouse.

hmm.. are you saying back pressure is good for higher rpm because at lower revs it creates the back pressure then at higher revs the valves stay open for longer so you're releasing all power + the air that's stuck to get some kind of huge power hit?
or am i totally lost? Confused
