I have no complaints about the exhaust covers better than no exhaust cover with actual tips that will eventually turn dull and rust anyways. good way to preserve the look.

I guess you can use masking tape around the perimeter and protech the finish of the bumper and ise a solvent to spray on and use a brush to losing the contaminants. That is the best way i can think of unless there is another solution.
