2017+ Kouki 86 Exhaust Hole Cover *Gauging Interest*

[RayRay88]

Hey everyone,


I wasn't too happy with the current offerings for the Kouki 86 exhaust hole covers. To be fair they'll cover the hole up but look awkward with the new faux diffuser lip that Toyota added to the 2017+ rear bumpers.



So I went about creating my own.



I had the rear bumper scanned and started creating a cover using Solidworks. I have access to urethane soft tooling and SLS/FDM 3D printers at work so it's pretty easy to design and put into production.



I was wondering if there was enough interest/koukis going single exit to try to put these in to production.


I'm about 90% of the way there. I have to print out a sample when I can and see how it fits.

RayRay88: may i suggest to try make one not just covering hole, but where one still sees that bulb of where one of exhaust tips had been, but making it much wider then exhaust cutout so to make it seem less of a hack, more like impression of bumper with really just one cutout on one side?

Sorry I don't follow. The impression of the exhaust is still formed in to the bumper. So to smooth it out would require cutting out that feature and remolding.



I've got the piece test fit onto my car, but it's printed in SLS Nylon (very expensive). Just waiting for my body shop guy to get back from vacation so I can get some paint from him.

I realized unless I got a commitment of like 15-20 per side I couldn't justify the urethane mold for this product and a finished/painted SLS 3D printed version would likely be $200+ a pop. I don't know if people are willing to pay for that.

With higher covered area and smoothed out exhaust cutout bulge by cover over it being wider and flatter, instead of just filling hole. So that bumper there looks less of like there been cutout.
something like this:

I initially thought of the same thing, but the curvature of the bumper does not allow that. Unless you completely fill in that area, and even then it would protrude quite horribly and you'd lose the over all shape of that area.
