Default How would you make an exhaust shield?

I am looking to make something like this for my bumper because the rear lip got a little burnt when my car was running really rich and I would rather do this then bother repainting it. Since they dont make one for my car, I need to know how I would go about making a model of it off my bumper to send to a company to make a mold and turn into a carbon fiber piece. What material would I use to make this piece out of and get it to size on my bumper? How would I go about getting it the exact size i want before I send it to the company? And does anyone know any companies, possibly one on here, that could make this piece for me? Thanks

.044-.065" thickness sheet aluminum and pop-rivets. worked well on both our shop cars and looked very nice. i can get pics if youre interested.

.044 is the thickness between a normal Honda spark plug - that would be easy to bend. You just have to be good with metals. Otherwise I'd say spend a bit more and go with thinner stainless. Not only will it be more maliable (easier to form), but resist heat transfer (pure Al is ~342 and SS is ~52 in terms of K/w transfer IIRC)

I mount them with some thin delrin or nylon washers behind them to space them out a little bit from the surface. Aluminum dumps heat so fast; I figure the air space slows down transfer.

If you are good with metal forming, polished stainless would be ****. Better thermal barrier.

this was a sheild my brother made. .044" aluminum from lowes. removed bumper, fitted/molded as best we could, then rivetted it all on. turned out pretty nice in my opinion. not to sure on function (keeping it from burning through), as the bumper was notched as well. it does keep the soot and gas-crap off that general area. tootles,

Thats a good alternative instead of the trademark DSM bumper stain

Finding a company to make a mold and make a peice of formed cf sounds expensive. Might just wanna shop around and see if someone already produces one for honda's.
