ace79 said:now my RS-R's middle pipe resonator pun dh selalu kena speedbreakers...lg mau buat straight? aiyoh...dun wnat extra trouble with the law, so wanna go thru EG hatch's standard piping ler..another question. If I'm not mistaken, if the pipe measurement ( taken from the outside of the piping ) is 2.5", the inside size must be 2.3" or so, right? My current piping size ( from the extractor and the middle pipe ) is both 2.5" outside, but 2.3" inside, correct ah?
yaa..need confirmation on this matter too.how do we determine the diameter of a pipe?is it from outer pipe or inner pipe?
