  • Best way to drill holes in heat shields?

    so i like the look of the black stock exhaust on some newer sportys, with the "buckshot heat shields"

    i have a buddy who is gonna give me a set of stock pipes and shileds, and some screaming eagle mufflers. i wanna drill holes in the heat shields then get the whole setup ceramic coated black.

    but whats the best way to get nice clean holes in these shields?

    also, does anyone have these that can tell me how big the holes are, and how far apart they are?

    say it with me.. Drill Press. Unless you have access to a punch.

    Take your time and measure twice, then check it again, lay it out with a sharpie marker and TAKE YOUR TIME. Nothing will F*ck up a project like this quicker than rushing it.

    Take pictures so we can see, as this sounds like a cool DYI modification.

        Well I don't have a drill press. Only regular drills, I guess if it has to be done with a drill press, I'll have to bring it to a machine shop for holes

          I'd paint the pipes. That way if you get a knick or a scratch you can touch them up. I painted my black ceramic thunderheader this past winter. It was 8 years old with some scratches and stuff. So far I like the results. Oh.. just reread your post. The pipes are probably chrome. I don't know about painting chrome. Maybe you can if you sand them. I'm not sure.

            If you take it to a machine shop have them punch the hole's, much cleaner holes!

            What are the holes for?

              To look cool! You can possible do it with a regular drill but it will be a lot of work. Use a NEW carbide drill. You'll need to use a center punch to keep the drill from walking all over the shield. You would need to punch it onto a mandrel of some kind. You could use a pipe in a vise and wrap it with a couple of turns of duck tape to make it soft enough to get a good dimple on the inside.

              Best bet is take it somewhere and use a drill press or better, have someone punch them. I would GUESS on the size as 1/2 to 3/4 inch holes, but it really is what you think looks best. Try marking them out with a stencil and black marker and see how it looks with different size holes.

                why not put a custom design in them or spell out the word HERD. then using a piece of stainless backing after you ceramic coat them, rivet the stainless behind the top shield so HERD shows through the black cover

                this option will definitely take some time............but you will have the only set on the planet.......CUSTOM

                    also guys, i can use these pipes without the crossover tube right? it has been cut off and the holes welded closed. i figure there are tons of pipes out there without crossover tubes.

                          Shit..... I just threw a pair out for a Dyna that were drilled...........

                          You wanna use a "Step Bit".

                          Go get them from Harbor Freight for $13 for 3. I use them all the time.....on Rotors and brake carriers......They allow you to cut a hole, then bevel the entry of the hole with the next size shoulder.

                          After:



                          Rear brake drum:



                          Rear brake rotor ans caliper holder:
