Just picked up my 15 pro4x this weekend and the previous owner installed a muffler swap. It's a dual in single out borla muffler he said jt is the pro xs model. Do they normally have a bad drone around 1800-2000 rpm? It's pretty annoying.....Maybe I'm just getting old

All Titans have a drone @ 1600 RPM's. Add an untraquiet resonator after the muffler, and it wil kill it. It's around $100 + labor. Oooorrrrr you can use it at an excuse to add full Cajun. Manifolds will eventually crack. As a married man, it always boils down to preventative maintenance or safety! :big_grin:

Then again, you may be getting old

Get a UQ RESONATOR from Cajun Bpipes and it will be gone.
