If this is an issue with a loss of power to the engine and you suspect the exhaust is the cause you will need to have an exhaust back pressure test done to see if there is a restricted exhaust component needing replaced.This can be common for a loss of power like this here.If this was already tested and found to be o.k. I would have the fuel system tested for any issues as I have seen a restricted fuel filter as well as weak fuel pump cause this needing replaced as well.
