Hm.
When I accelerate normally in comfort mode I do experience some drone, but while maintaining a constant speed I don't notice drone. It's more just the exhaust noise but it doesn't vibrate the car or sound unpleasant. At least that's how it is for me.

The range I get the most "drone" is anywhere from 2-2.5k rpm, but my mom doesn't even complain about it so you should be fine.

What size piping did you go with? I'm assuming 3"

Hey, I know this is late but I was wondering if the valves still worked for you when you kept the valve actuators? Thanks !

Yeah the valves still worked but it didn’t make any difference in sound. I ended up tying it open

Thank you for the reply ! The videos of the muffler delete you linked aren’t available anymore. Is there any possible way I would be able to see them ? I want to make the right move. Thanks !

I can’t find those clips anymore but these videos sound pretty close to what a muffler delete sounds like in person:

Thank you so much for replying ! Do you think if I were to do just a muffler delete and not the same pipe setup as you it wouldn’t matter and still sound the same as yours ?

Yeah, I think they would all sound the same regardless of how the piping is done

Yeah I’d remove the valve if I were you, all it did was rattle on my car
