Oem Exhaust Drone

Hey guys, I just got the exhaust done. Sounds great! Gives a great growl to the car, except I just feel as if there's a bit drone even just cruising around. Around 40 I have to tap the gas peddle somewhat lightly to not hear it but if I put my foot down a bit you can start hearing a lot of that drone. I don't know if that's the same case with you guys or not. Maybe I just have a heavy foot haha.

I had the ACM previously with DCT and never had an issue with drone.

Well I haven't noticed anything similar except for knowing the exhaust does drone around 2k-2.4k naturally. Never noticed anything extra and I'm running test pipes also.

My OEM exhaust drones at 2000 rpm in the higher gears. It's a very narrow band, though, easily overcome by shifting to a lower gear to raise the revs. I wish my M3 sounded more like my old Audi RS4, though - no drone whatsoever, and a mean, rich rumble when on the throttle!

Yeah when it becomes around 2k that's when it starts droning a bit. Gets somewhat annoying

never ever had any drone with the OEM exhaust, so quiet. Even with the ACM I had zero drone. Best exhaust mod for the price.

You want drone... get in a car with straight pipes

how audible is the drone? Enough where you can't carry a conversation?

I can control the drone. If i am on the highway and cruise in 6th gear instead of 7th gear. the RPM stay little higher, and believe it or not the drone is 100% gone.

I only do this when i have other people in the car, personally doesn't bug me.

If you've done the striaght thru design or replaced both perforated pipes on each side, that would explain some of the drone.

I replaced only one pipe on each side and mine sounds fine. Not as loud as straight through design but also no drone.

My MPE drones at just around 3000 rpm at a steady cruise. It isn't bad, but definitely a steady hum. It isn't difficult to avoid.

Yeah I did do the straight through one, is that any worse than the regular one?

+1 for my OEM mod

3,000rpm in 7th seems most noticeable but pretty bearable. I got to test first hand last week doing road trip from NYC to Williamsburg, VA and back

My more pressing issue was the thule cargo rack that was bloody loud >50mph...

My PM won't send for some reason but here's my reply! Haha reply back in a PM idk why my message wouldn't send .. But I have the same feeling about the corvettes! One day I think they're exotic looking and the next it just looks like an everyday vet to me. I've only seen like 4 c7s around my area right now so I haven't really been like a huge judge on them but if I get a c7 it has to be a zo6 but Deff not brand new. Way too much $$. Probably would wait a year or 2 after release. The gtr I've loved since a kid.. Especially the R34. I wouldn't get it for the insane speed I'm just in love with it.. But a lot of people made me lose my love for it. The interior and the sound system and I want an a manual. I'm honestly lost on what I want haha. The new Camaros coming out in the future look dope tho. Hbu? What you looking for. I'm somewhat interested in a carrera s

OEM exhaust without any mods, 100% stock, has some drone under certain conditions.

People saying they never had any.. makes me wonder.
