These look amazing! Interesting how it's currently way too loud. I'm personally hoping the end-product sounds just a bit louder than their current single-tip axle back.

Coming back to this post since Apexi FINALLY posted a clip of their quad exhaust for the 21+ IS! A day late, but I've been waiting for so long.

I still prefer the angle stacked looks of the IS500. Does anyone have more info if the is500 would fit or closely fit?

If all you're after is the stacked, quad exhaust look on the IS350, my boy does have the TOM'S exhaust on his and the diffuser, you MUST get the diffuser, remove the rear valence, and do some cutting to make it all fit..






After all of that, he still says he prefers the sound of my Remark Exhaust

Coming back to this post, have you been able to test fit the IS500 rear valance/diffuser? Any diagram I get from looking up that part # is just showing exact diagram of the IS350's, so I would assume everything should fit and all clips would be reused.

Also, does anyone have any clips of the 2021+ IS350 with the Apexi quad tips and midpipe? I'm sure it shouldn't sound too different from prior 3IS with the full Apexi setup, but I would still love to hear it!

I am pretty sure it'll fit. Everything on the rear fascia is the same except for the gloss-black section at the bottom.

Thumbs up

The IS500 rear diffuser fits on the IS350. Bought the part from Lexus part #52108-53100. Had my mechanic install it and he said it was a 1:1 exact replacement. All clips line up but old clips and reflectors must be re-used onto new part. Since it's still an IS350, the hangers for the exhaust are now noticeable with the IS500 diffuser.
