its time to start playing with my engine, its the ye old 165kw v8 from 1996,

i noticed that the exhaust header pipes are almost "crimped" where they join on to the heads, this cant be good for easliy flowing exhaust. how much would it cost for some good extractors, i know nothing of whats available or whats good or bad. it appears that the pipes are 3" from the headers, then join into 1 x 3" pipe that goes all the way back to my muffler, eventualy down the track i'd like to change the heads and the cam shaft, but cant do that yet or ill sacrifice my warranty. what kind of costs will i be looking at and how much improvment will i see.
