Does anyone have 3.5 quad tips on the stock 17 diffuser? Most of the pictures I found browsing around were with aftermarket diffusers. I'm wondering about the fitment. Measurement wise it seems it would be quite close.

Bump. Want this

You need to measure how wide your stock diffuser opening is. Each of my tips is 3.5" and the opening is 8.3". If yours is less than 8" it wont fit.

Did you change out the stock diffuser or is that an aftermarket one?

Funny that you've got the UH bumper on the car. I'm writing this post at UH in class right now! LOL.
OP I've got an exhaust coming in a few days that has 3.5" tips on it. I'll let you know and post a pic on how it fits with my 17' IS!

Would quad tips fir the RC fit on the 2017 IS diffuser? Any recommendations? I want them to follow the same fitment as the oem rectangular tips. I don't want them to stick out and I want them to fill out the same lines as the current ones so it looks nice and clean. Given the shape of the rectangular ones, they'd have to be slightly staggered. Thanks.

Apexi makes a quad tip axel back exhaust for the 2017 diffuser.

Here's a link to the vendor post.
