2017+ Kouki 86 Exhaust Hole Cover *Gauging Interest*
 

Hey everyone,

Thought I'd post it here as well since it pertains specifically to the 86's

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.:iono:

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

This looks GREAT IMO! Flows well with the rear diffuser. :thumbsup:

Intetested. But for pass side as well?

Would be easy to mirror the part and create one for the passenger side. I assume it would be identical. Would need to check with someone local.

Been needing one of these for the passenger side.

I have also been thinking... Why hasn't anyone made something that goes over or replaces the rear bumper piece altogether? And I'm not talking about a fancy one, just something that looks stock but looks like there was never that other hole?

^ +1, gimme a whole piece.

I'm not sure i follow. Do you mean like a brand new "faux" diffuser section?
One where you would have to cut out the old one and some how attach it to the bumper?

I think they mean the entire diffuser. That's how I feel, there's nothing for single exit, it'd be worth $400 to have a nice unit that also looks better. Or just does away with the matte plastic and goes gloss

Yes the entire black part that encompasses the bottom part of the rear bumper, with the 2 exhaust holes and the hole for the triangle light.
I believe it's removable, since I've seen people with their's intentionally removed/replaced.


Not one necessarily requiring you to cut out a hole. One could be made with a driver side hole only, and an entirely separate part with only the passenger side hole. You purchase the one you need.

Although I've been thinking.... Maybe someone could just use the existing exhaust hole covers available on the market, glue, fill the crease with body filler, smooth out, then use vinyl to wrap the whole diffuser so it looks smooth.

That rear portion is not removable. Those that have done it have cut them off with a dremel or similar tool.

Oh, that's what you meant by cutting it out. I didn't know.

Plan B? i dont know.

this is for 2017+ models. The rear diffuser is not removable on these models. I believe on the earlier models (1st gen if you want to call it that) are removable but I could be wrong its the only model Ive seen with them removed

The black part on the rear bumper of the 86, FR-S, and BRZ is not removable, you have to cut that part to remove them. For example to add the rocketbunny rear diffuser you have to cut the stock out.

There is a part for the early models, 16' and earlier, that would add a faux diffuser pictured below. Not sure if they have something like that for the later model, 17+.

Any updates? Still very much interested
