noise in cabin on Esiemann Race exo

zz10 · 04-29-2012, 01:31 PM

Gidday folks, I have this 'droning' noise in my cabin after I install the Esiemann Race exo, are there any other solutions to cut off this 'droning noise' effect? Its not very pleasing to the ears.

Happens when I start at 2 rpm onwards, and the noise will be done should I rev to 3.5 rpm, or when I let go accelerator.

Not really. Install resonators?

If you install some Vibrant 1792 Resonators in your mid-pipes, that should cut out some of the drone.

tscdennab · 04-29-2012, 02:19 PM

Resonators do not help at all with drone, only with rasp.

If you want no-drone, sell the exhaust and install a BMW Performance Exhaust, it's the only one 100% designed to be drone-free.

Also the HKS exhaust is known to be drone free. I think anything with "race" in the name for exhaust will have a tendency to drone.

That's what the Eisenmann race exhaust is supposed to do past 2K and up, make NOISE!!! What's their motto, driven by sound. You could've bought the sport version, less quieter than race still louder than stock.

Trade me for my oem exhaust lol

if you have an e92, put a towel in the rear compartment between the seats...make sure its in there really tight

Hks is drone free unless you try to go up a steep hill in too high of a gear. I run it catless and its great

I'll buy it.

1 or 2 tennis balls work just as well.

I have Eisenmann Race with catless downpipes... Its literally 20x worse.

Not much you can do aside from adding resonators (mixed results, generally little to no help with drone).

BUMP for others to chime in with suggestions so I can try them too

indeed... but I often cruise on the car then actually revving it.... I got this Race 2nd hand at a good price, and that point of time no one is selling the sports version...

indeed! a bit uncomfortable to the ears... I have a friend whom operated on the Sports version by not joining the centre short pipe connecting between the exo catback.. and it really cut down on the noise..

u could always just get quad tips welded on any exhaust.

Wes335XI · 04-29-2012, 11:20 PM

You're my hero. The guy with the two tennis ball idea. Going to try it when I get back from vacation. It's the most annoying rattling noise and I could not figure it out.

Thanks!!
