this is about a full exhaust system for glanza v

starts off has 3 inch system then goes to stock exhaust it keeps the gas in exhaust warm give you better performance then its got 4inch tail pipe

is this true or false this will be the decider

If the pipe work narrows then gets larger again it's going to restrict the flow of the gases, so it's bull.

been worded wrong the pipework starts off 3 inch then starts to reduce bit by bit till it gets to backbox keeping constant volocity off gases has it moves down the exhaust pipe
