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
