recalibration for new mufflers?
I have a 2000 Ultra with fuel injection. If I install aftermarket mufflers to make the exhaust sound better ( I assume they have less baffles, back pressure?) does the engine need retuned or recalibrated to run properly?
Is it possible to core-out the stock mufflers?
