No-Drone Catless Exhaust Systems

gilberjj · 06-27-2020, 01:02 PM

Hello everyone,
I’ve done a lot of research, and it seems like the only systems that don’t drone with a catless (resonated) x-pipe are:
Corsa
M Performance Exhaust V2
Active Autowerke Signature V2
Akropovic

Maybe Agency Power/Megan as well. Getting mixed reports...

Am I missing any?

Edit: OEM mod also doesn’t drone

I had no drone with 2 pipe oem mod

I have the borla mid pipe on with an atak muffler. there is some drone around 3.5-4k depending on how much throttle you input. you can keep the inside sound levels anywhere from pretty damn close to stock to crazy depending on how much throttle you give.

Also....I do not have a tune yet and do not know if that could effect the exhaust done with different VANOS mapping at different RPM.

You forgot to add Dinan to your list....

You might want to remove the AA exhaust off your list, there is drone. Out of all the exhaust setups I have tried in your list, the only ones that don't truly drone are MPE v2 and Akra.

Even the OEM 4 pipe-mod has some drone down low. Drone is very subjective though, some might think of just even a tad bit of bass = drone. It all really comes down to what type of sound you like.

Currently have the MPEv2 with catless test-pipes and I can 100% tell you there is no drone, rasp if anything.

Dinan doesn't drone either. I saw that AA came out with a V2 and supposedly has less drone

No drone with dinan. I have full catless system with dinan.

I have a Dinan Midpipe to a AA Muffler and no drone to report here

OmairK · 07-07-2020, 07:34 AM

Dinan Mid-Pipe and Dinan Axleback - No drone and sounds amazing. On the quieter side of Catless Exhaust Systems as far as the S65 and E9X M3 goes but sounds AMAZING when you're on it.

take megan off the list. There is a drone around 2-2.8k rpm; will swap out the megan with my oem 2.5 pipe mod and see if it's better

TDW_Nero · 07-07-2020, 05:50 PM

Akra rear mufflers paired with anything will have no drone

BURAKUSTA · 07-08-2020, 08:49 AM

Test pipe
Quad resonators
Akra rear
Zero drone
