Ipe exhaust drone
Hey guys,
Installed my new Ipe innotech exhaust on my c63 (2014 with eurocharged v5) yesterday.
It is a CAT back System.
Everything works flawless, build quality is great.
But one little problem - it drones at low rpm (1500-2200) - also with closed valves. Didn't know any drone with oem exhaust.
Any solutions to kill the drone?
Thanks for all suggestions!!

one idea is to weld the OEM resonators back in but is unknown territory it terms of end result. you could also try riding in a car with the eisenmann race exhaust and then appreciate the relative quiet afterwards

Obviously, I can't know if JR is kidding. But there are some threads on this forum about drone from the Ipe exhaust. Attached is a link one and one of the comments.

Is the drone unbearable or is it only noticeable if you are looking out for it?[/
The drone was initially unbearable when driving slow for the first 2 weeks I had it then I got used to it. It only happens when accelerating again under load in that rpm range. Higher rpms, the drone disappears. Again this is due to primary cats being removed I believe. The car will also need to adjust to it as well as my car ran a little rich at the beginning due to exhaust smell and then toned down a little a few weeks later. Exhaust build quality is awesome though and for the price it's exceptional. There will be a break in period for the rear mufflers too so you will notice white residue and smoke within the first five days....normal so don't worry about it....just residue burning through inside the muffler. With the valve open it is loud but sounds like a race car. It's a tuned sound and not a messy loud sound like some other c63 I've heard with other exhausts. Overall I like it but as I've mentioned ive planned to put factory cats and headers back in to drop the sound a little.

Found That thread a few minutes ago.
I only have the cat back system.
He mentioned the drone comes from deleting cats.
It is really annoying as it drones exactly at Highway cruising Speed

The drone is normal and it is due to no primary cat. I asked for the 200 cell cat kit and this helped but the drone remained. You can try adding 2 high flow resonators or a resonated 3 in x pipe to replace the ipe rear section x pipe. Only solution for my daily driver was to remove the header and use a shorty header with the oem primary cat. That is my current set up now and has been for the past year. You will loose a lot of power without the header but it's a happy medium if you use the car eveyday.
I would say drive it around for a month or so and see if you can get used to it. If not then add resonators to lessen the sound but keep the flow. If that doesn't work then you need to go about putting a shorty header in or the stock headers back with cat.

Ok if your running cat back only...do you just have the rear end which starts at x pipe? Any other mods to exhaust like removing secondary cat?

I had no drone with the cat back set up. However once I installed the full system then I did start to get a drone at bang on 70 mph.......which is a little annoying. However at 75mph it goes away.
Still love the fact I can open the valves and make it really loud or have them closed and be fairly civilised.

I think it is because the cat back replaces the resonators. I have MBH lth with catted mids and x-pipe to the stock cat back and I get no drone.

Just found another post here:
"Without adequate exhaust gas volume(just cruising/not stomping) the exhaust pulses will start to collide and cause droning."
What is meant with adequate gas volume?
Damn, I start thinking, that I should have kept the OEM exhaust alone...

The end result is to replace the ipe muffers with something else.

I'm from Germany (94315 Straubing) - and jop it is an estate 
Basically I would be more than happy with the exhaust. Sound is awesome - really deep and powerful. Poweroutput is good. Even downshifts are smoother, it does not kick in so hard any more.
But I am really sensitive for any background noises - and my wife even more.
She already does not want to drive with me anymore - and the exhaust is only 2 days old now
