Mugen rear. It’s not 2020 because the vents don’t have the hockey sticks.

I’m gonna check with HKS why the Spec L doesn’t fit with the new diffuser. It doesn’t seem like any other exhaust has this issue.

These exhaust tips looks like positioned in a larger position than others exhaust tips.
The 2 rear compatible diffuses are the stock before 2020 (pictures in to the video) and the Mugen one (all revving sections).

In the beginning of the video, yes it is the pre-2020 diffuser. But the part where the car is revving, it has a different one that looks like the 2020 diffuser.
My bad, you’re right I didn’t finish the video. Like blue hatch said, Mugen add-on diffuser.

I got in touch with HKS and they said the new style diffuser is too narrow and makes contact with the muffler. Not sure if they meant the tips or not. Part of me feels like it will fit with minor modification ie. bending the hangers but I'm not really willing to risk $1k to find out lol.

Where did you get yours from? Do you still have it on? How do you like it so far? Any drone? Maybe we can meetup at a Civic meet after the Holidays around the South Bay. Looking to get this exhaust.

Edit: Oh. I realized you have an Si instead of a hatch. Exhaust may be different.
