Trimming Rear Bumper Diffuser for Tips

[Rynil2000]

For those that have added larger aftermarket exhaust tips and had to trim the rear black bumper trim, what methods did you use? What tools; Dremel, saw, oscillating tool? Are there any suggested tip or tricks that you can recommend? I have cut plenty of ABS before but just wanted to see if there was any direct experience out there.

Even though I have the oval tips that fit through the stock openings, there is some rubbing that I would like to eliminate. I'm hoping to get rid of some minor rattles at idle and perhaps some more cabin noise.

I'm leaving this SEXY trim job by @xot1 as inspiration...

Nothing fancy. I used a metal file and some elbow grease.

I used a very sharp utility knife to take out the bigger pieces and then I made it less jagged with a dremel. I had to take out quite a bit. I am actually hoping the 2021 stinger rear diffuser has that huge opening that will fit on the older stingers and not require trimming.
