Has anyone upsized the entire exhaust system on their 3sge altezza and noted any performance changes?
Moreover is there any sensors on the resonator or along the piping that would pose a problem to change out the entire stock exhaust to a 2.5 inch or 3 inch system?

Hello. Without getting an ECU and a remap generally you will not notice much of a performance difference. With regards to the sensors i do not believe there are any in the Cat or Back Box. Not sure about the header. If you buy the correct exhaust for the car it should come with these attachments anyway.
