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.
|
that all depends on how mismatched the cam is to the rpm range 
the backpressure myth stems (imho) from V8 kiddies who put 300+ deg cams into a motor that revs to 5grand and (miraculously) they find that they need backpressure to keep the mixture in the cylinders....
backpressure is a myth. a well designed exhaust system helps the exhaust get sucked out....
