Forcing the valves to stay open all the time? Plenty of people have.

My muffler guy said he do it for me but I'd have to bring him an additional muffler. He wouldn't try on my stock cans. Should sound rougher but my car already sounds pretty loud without the resonators. 🤷🏽

I've actually done this to my F86 with catless downpipes. I'll be back home on the 15th of Sept after which I can send a sound clip. I just replaced the perforated pipe with a straight pipe. There is a slight drone in the cabin and some rasp but overall i'm happy with the overall sound. Last edited by islandman; 09-02-2021 at 08:31 PM.. Reason: error |

I disabled ASD and unplugged the exhaust valve plug when it was open. Sounds perfect as it's real exhaust notes, especially when the windows are down.

BMW definitely missed the mark on our exhaust note. My C63 sounded far better in sport +.
