Borla rear diffuser adapt to fit? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I just noticed... the Borla diffuser mounting brackets are all separate.

Has anyone tries to mount this to a non-borla exhaust? Looks like it's certainly possible. Just some different mounting holes need to be drilled. I like this as it's much more low profile than other available options, and allows retaining the stock diffuser trim.

Question is how effective it would actually be....

It definitely helps with the borla catback. Without it the ass end of the car is way too squirrely. I went without it for a few months and when I put it on there was a very noticeable difference.

Let me ask, did you see the one for sale and that's why you are asking? I was debating doing the same thing, haha. I'm sure with a reasonable amount of effort you could make some adapters to fit it to the car.

Nope. I was just looking for alternatives to the cleib diffuser (whcih can't be bent/adjusted if it doesn't clear my exhaust, and the speed factory one which sticks out too much for my tastes. I just want an underside that's as flat as possible...

If I could pick one up for cheap I would definitely give it a shot myself. Might be a little bit of a project making some new mounting hardware, but that doesn't seem so hard. I'd probably add some extensions so it went further under the car to fill in more space.
