Berk Dual Tip Muffler Delete Drone
I just installed a Berk dual tip muffler delete on my BRZ. This is the first time I have ever messed with the exhaust on a car. I am happy with the deep sound it makes, however at around 2.3k and 4k rpm, it drones really badly.
Is there any way to fix this? I love the sound except for that drone! I bought it about a week ago and I can't get over it. I am thinking I will have to return it if I can't fix the drone. Is there a way to get rid of the drone? If not, is it possible to return the muffler delete to Berk if it has been less that 30 days? Thanks. |

Yes, I kept everything that I took off of the car. Sorry if this is a stupid question (I am a completely new to exhausts) but is the muffler and resonator the same thing? If not, where is the resonator?

If all you did was replace the axle back, which is what the Berk is, then there should be very little drone. I have a Mach V dual exit delete, 2.5" overpipe and catless front pipe and I love the sound. Is it loud? Hell yes when I get on it. But I have learned where to keep the RPM's to keep it calm. Right around 3k RPM seems to be the sweet spot for me.
Also, if you JUST put it on, give it some time to get coated with some exhaust soot. That will tone it down a little too. |

Well it was pretty quick for me as I am down 1 cat. Give it a couple weeks. The tips will turn black inside then you'll know. It'll get more and more coated as time goes by.
If that still doesn't fit for you, I'd a get a front pipe with a helmholtz resonator. Nameless Performance makes one. I would advised if you do this, take your car to a GOOD muffler shop and have them make a 2.5" mid pip with a silencer. I say this because I originally put my muffler delete on first and it added a kick in the pants. When I put on the overpipe and front pipe, I feel like I lost some power. After watching a very informative video on exhaust design, I think it added a vacuum pulse that wasn't there before and jacked it all up. |

I'm going to add a tally to the "don't hold whatever rpm you hear your drone at" clan. I also recently installed the Berk muffler delete, single exit flavor, and have noticed drone in certain spots.
It even drives one of my buddies so crazy he hates riding with me 😂 so I usually just change my speed for the gear I'm in, or down shift, or turn up the radio. Sent from my 831C using Tapatalk

I too have a Berk single exhaust muffler delete. I love it and have no complaints. I must admit that i don't even know what drone is so either i don't have it or i like it. Please advise.

I'm almost 100% sure it's sensory adaptation and you getting used to it, there is no muffler or muffler walls to speak of to get coated in carbon for any sort of sound difference to take place, it's literally just a pipe. If he really wants some less drone , he should take it to a shop and ask them to weld in a resonator in the pipe that runs between the two tips. I also agree with getting the nameless front pipe with helmholtz resonator, and you might as well get the nameless mid pipe as well because then you'll essentially have a full header-back done, because the nameless front pipe replaces the overpipe as well
