Reducing exhaust drone? So I recently installed a aftermarket exhaust system, the invidia q300 to be specific. I love the sound but the drone could get annoying during longer trips. Are there any suggestions to reduce the drone? Sent from my SM-N910W8 using Tapatalk |
Silencer if they offer one. There isn't so much you could do honestly. |
Install resonator? |
Install a resonator, something like a glass pack will reduce your problem, perhaps even eliminate it. |
A resonator would require cutting and modifying the exhaust, correct? I have read that the exhaust has to be broken in, and it should mellow out. Not sure how reliable is that information. Sent from my SM-N910W8 using Tapatalk |
Yes, a resonator will require modifying the exhaust. |
I suppose it could be broken in if there is some sort of fiber filler in the muffler itself. It depends how your exhaust is made. |
Resonator, or get a knowledgeable exhaust shop to fab a helmholtz resonator/anti-drone tube. It will require very precise measurements and mathematical calculations to get rid of drone in a specific rpm range based on the length and diameter of your piping. |

It's a weird phenomena... First day I get an exhaust, I almost feel embarrassed driving it around. few weeks later, I'm wondering now what if I got a louder one... hmmmm..... |
Not used to it... Deaf to that frequency. lol |

I don't think my comp tech header and high flow cat is helping. Unfortunately invidia doesn't make a silencer for the q300 but they do for the N1. I don't really mind the drone but my wife finds it atrocious. Lol Sent from my SM-N910W8 using Tapatalk |
If you don't mind me asking OP, which vehicle do you have? Adding a resonator is usually the first line of defense...Vibrant makes good resonators. Also, usually exhausts get louder after the break in period IIRC. |

oem exhaust is best exhaust |
had mda fab install/weld a resonator on my invidia exhaust and no more drone. |
If you think the Q300 has too much drone then i suggest you just keep the stock exhaust on. 95% of the aftermarket exhausts are louder than Q300. |
