best way to cut the rear bumper

[Miatafreek]

I have just done a new exhaust install and I have to trim up the rear bumper and I want the cut too look semi-pro not like I hacked it with a dull saws-all, any advice I can get I will take.

A saw-z-all with a new blade... or a variable speed Dremel with a nice cutting wheel...

The best way is not to rush the job... just take your time whichever method you use.

Being as I just did this for my Racing Beat Duals install... I'd suggest what they do...

Mark out the size you want the whole to be (RB provides a template for this). Then... mark a dotted line about 1/8" of an inch inside that. Cut to that inside line. As for cutting, I very carefully used a dremel tool with a cutting disk in conjunction with a box knife to rough out the opening. to the dotted line.

Then... use some 200 grit sandpaper to gradually expand the opening to your your final line. This will take a little while, but gives you a very nice opening and reduces the likelyhood that you will remove too much material.
