Because the tail pipe is fixed, I couldnt limit the drone by lengthening the tail pipe. I was able to eliminate it by inserting a tail pipe baffle for a motorcycle. Car Chemistry Exhaust Inserts 3DI25R fit the tail pipe perfectly. One in each tail pipe with one section wrapped in their sound deadening steel wool was the perfect solution. The car still has a growl but very liveable in that rpm range.
Did you need to use the set screws with those inserts or do they hold pretty well in the pipe without?
