Wanted to give a plug to APR for their Helmholtz resonators that they’ve recently released. It was the missing piece of my setup, and I’ve finally achieved what I’ve been after on my Golf R. I still kind of can’t believe it.
My setup is stock cat -> vibrant 17950 bottle resonator -> APR Helmholtz resonator -> Nameless Performance muffled catback
Exhaust valves have been cancelled as I never found myself switching between modes really.
It’s got the look, the deep/grumbly tone, the subtle “farts” if you will, and the extra but not obnoxious decibels that I was after. Most importantly it now doesn’t have that annoying 3-4K RPM drone. AT ALL. There’s literally none in any scenario. Kudos to APR for this thing because I was skeptical af but this is truly tuned for that specific RPM range like they said.
Hope this helps someone in the future. These cars don’t have to sound like shit or tractors. It now sounds like a sophisticated sports car.
For reference it’s the APR MUH0015 that has an indent for the driveshaft:
