Valve controller using mirror buttons

I’ve installed an exhaust valve controller on my LC500 and wired it to the garage door buttons on the rearview mirror. Anyone else done this?

The difference is night and day — especially right after startup and in everyday driving. The exhaust stays noticeably more burbly and alive once warm, giving the already musically perfect 5.0L V8 a deeper, lower rumble in situations where the valves would normally stay closed (below ~3,000 rpm and under 50% throttle).

It adds real drama without being obnoxious. Lower-rpm downshifts are way more satisfying now: 3→2 at around 45 mph gets noticeably louder with occasional sharp burps, and 2→1 finally has that proper, grin-inducing pop.

I love having the quick-toggle right on the mirror buttons — super convenient for switching between stealth mode (early mornings/neighborhoods/wife) and full visceral fulfillment…

Has anyone else set one up this way?

I have a PPE Dual Mode Exhaust, and I control the valves with the HomeLink buttons on the mirror

Did not wire it in, but my exhaust came with a wireless remote which I've mounted to the glass just above the mirror, so almost as simple as the HomeLink.

^^^^My exhaust did also. I programmed it for the HomeLink and threw the tiny remote in the 🗑️

Yup, I did the same with the exhaust controller. At idle it's really hard to tell, but definitely below 3,000 rpms it sounds much better. I've considered an aftermarket exhaust, but I think it's actually perfect the way it is.

I've programmed my exhaust to a Homelink button as well. I love having the exhaust open so I never use the button, but it's nice to know I can adjust if I ever need to.
