It made a big difference on my 2010 Ultra Classic. On my 2015 Limited the heat is no where near that of the 2010 Classic. I'm just going to leave it alone.

You may run into a tuning issue after you break the cat out... The O2 sensors are pretty close to where the cat is and with it gone can cause the sensors misread the exhaust gasses.

Wouldn't this be where a tuner would be useful? Such as but not limited to a FP3 or a PV?
