HI All

Another question, I am thinking of buying the stainless tyga exhausts from jap 4 performance but believe i will have to change the jets in the carbs? i know we need certain amount of stoichiometric air per kg of fuel burnt etc but surely if the outlet diameter of the exhausts are the same as the standard ones then we should not need to change them? or is it because of the smooth finish on the inside of the expansion pipes allowing exhuast gases to pass more freely allowing more air in hence changing the jets for amount of fuel? Also does anyone know what size jet would be needed if need to do and where i can get them? Thanks.
