Post by markmitchinnh »

I am modifying the stock rear bumper and one idea is to run exhaust out through it, does anyone have any idea on how to cut round holes in steel?

Hole saw. Be sure the saw is for steel and not wood.

I like that! Hmmm... I might do that. Looks cleaner than dangling down, and only need the tips to look good. Maybe a few holes for rear facing spotlights? I also like the hole for the trailer wiring, too.
