mileage loss
started with an '07 ultra classic with SE Prostreet slip ons. used dynojet tune that was loaded on PV
changed to 4"jackpot slip ons with quiet baffle & PV with tune from PV.
Bike runs good, but I'm only getting 85-95 miles before fuel light comes on.
used to get at least 130-135 miles. any ideas?
Still going same mileage to & from work as before.

the fuel light is a bad indicator...what MPG are you seeing?
use the trip meter to record mileage between fill ups, record the number of gallons you buy
do that for a week or so, if you haven;t
you should be seeing 40 MPG or so if you are running 70 MPH or below

don't trust that fuel light, trust calculated fuel mileage... thats the best way to figure it out... my 2012 ultra varies between 38 and 43 depending on how i ride and if my wife is on the back... we don't do hardly any city riding, its mostly out in the country and mountains

that would mean much of your gas isn't being burned for power...you are piling up carbon deposits in the combustion chamber and exhaust, you are possibly getting raw gas into the oil.
and not making good power
revisit your "tune"
if you bought from fuel moto contact them for mapping advice
try your old tune- when you say " 4 inch" mufflers- that's the outside diameter...what counts is the internal passages the gasses go through
