Resonators and cats kill drone. Mufflers kill volume and sound.

 

I have an appointment to get a magnaflow muffler installed next week. Going with a single in/single out somewhere midway under the car. Figured I would start with that to turn down the volume a bit.

 

Magnaflow will sound nice I bet. They tend to be mellow. Send sound clips before and after!

 

Do you have the factory muffler? A simple solution would be to reinstall it

 

I do, but I had a shop make a custom y pipe out to the tips. The magnaflow with make a nicer sound.

 

Replace the section beyond the deleted mid pipe with 3" and a 20" resonator, take that back to a vibrant single 3" in to dual 2 1/2" tips. Make sure to get at least 20" (body) resonator.

 

I have both resonators and the center "chamber unit" deleted with an x-pipe system. I still have the OEM suitcase.
Let us know if adding the Magnaflow muffler gets rid of your drone.

 

Diesel versus VR6 will have very different frequencies emitted so it wouldn't be a straight line comparison unfortunately.

New2, do you have any videos? I'm not sure if I've heard your egg yet

 

Finally got it done. Very happy with the results. Still has a decent tone, but is less obnoxious.

I have before and after video, not sure how to upload to here. Tried to attach but they too large. Ideas ?

Easiest is if you have a Youtube channel. Upload then post link. You could also upload to a cloud storage (Google drive, iCloud, etc) and post a public link.

 

Not doing the youtubes.... let's try this.

 

When I click on either of those videos it tells me an error occurred and to try again later.
Anyone else have any luck viewing them?

 

Is there some annoying drone in the cabin around 2,000-2,800 RPM?

Get one of these high flow all metal cats from GESI. This will tame some of the drone, will greatly reduce your emissions output and will maintain all the performance of that 3.0TDI (do you have an ECU tune?). If you are doing it yourself then you can weld this stuff in and listen before moving to the next step. Otherwise find a good muffler shop that will let you add each component and listen before trying the next part. Maybe the GESI cat is enough and you don't need to go further (and if you have the resonator and sport mufflers I mention below, those can be returned and money saved!)

But if the drone is still too much, time to look at a resonator...

Plenty of good resonators out there from Vibrant, Magnaflow, MBRP, Borla , Summit, etc. This should resolve the drone issue and give you a nicer tone overall (I prefer this route over straight piped for a daily driver). Again you can stop here and listen to the sound to make sure you're satisfied.

If it is still too loud, then I'd look at the sport mufflers from the aforementioned manufacturers. Should get you right in the sweet spot and still maintain performance.

 

They work on my laptop but not my phone.

 

They worked on my phone. Sound real good. What did you end up putting in?

 

14" magnaflow. Can just see it there before the fuel tank.

 

Tried them again today and they both worked.
Sounds good. Has a nice sound.
Did it get rid of the cabin drone?

 

Very nice. Any driving videos?

 

I could, but you really can't hear much exhaust over the tire noise.

 

Interesting so it's pretty quiet in the cabin? What about from the street? Like a drive-by, is it easier to hear there?

 

I'll try and get a drive by or take off tomorrow. To me it seems really quiet, but I was used to how it was before. I'll do a inside video in the morning when I run to the dump.
