    You will need to retune the ECU for the changes suggested (sans catcon).

    Run a search... There's plenty of example where people have installed straight downpipes without converter. You absolutely have to TUNE for that. You can NOT just cut out the converter. Muffler or not makes less difference than the cat....
    You can't have everything - where would you put it?
