The problem that you are having with the exhaust is due to a restricted catalytic converter. best recommendations is to replace the cats and have a diagnostic on the engine. you may have a fuel enrichment problem do to vacuum leak or improper air flow meter causing extra fuel to be added to the system. this will fill the cat. with carbon and stop up the heated ports, at 50% it changes the temperature drastically. This can do more damage if not properly diagnosed, find a good technician to repair it if you do not have the skills needed to perform such diagnostics.
