R36 Deleting the exhaust drone accomplished!

[Mr R36]

If you own an R36 you will find nothing you dislike about it; it is amazingly balanced in all areas and consequently very pleasing. However some things can be better. One of those is the exhaust note.

Many R36 owners will tell you they want more rasp and less drone from the big 3.6ltr V6 similar to the note of the R32s. But the investigation generally stops when they find out a full iPE or Supersprint exhaust costs upwards of $6000.

What did I want? I wanted the same reserved R36 at idle and cruise speed but with a little more bite at heavy throttle and I wanted it to be noticeable. I wanted that exhaust crackle akin to the AMGs. Essentially i wanted "loud on demand"

Well folks, I did it and I fixed mine for a total of $1100. What did I do? I simply upgraded the catalytic converters to 100 cell hi-flow cats and deleted the centre suitcase muffler in replacement of a J pipe such as the C63 AMGs have. The result? A nice loud raspy crackle at heavy throttle but almost stock noise level at idle and cruise. To me it's the best of both worlds without the hefty cost. In the future I think I will look at a REMUS rear muffler with valve control to control the noise levels at the touch of a button. Alternatively and or additionally add an air intake before the DSG and ECU tune and I think we may have struck gold.

I had my exhaust worked on at The Muffler Man in Prahran. Trevor and the boys know their business very well and have very good service. I can't recommend them enough. They stock loads of REMUS products are starting to focus more on VWs exclusively. Also if you try an exhaust and don't like the note within 14 days they will swap it back free of charge.

As you can tell in pretty wrapped about the new sound of the exhaust. Smiles from ear to ear!

Who's going to try this first in Sydney?

What is a J pipe?

No drone even in 5th or 6th gear?

Very interested in this!
As above - what is a J pipe?

How is around 3-4K rpm in gear 5/6?
I've only got a Suitcase delete and around 3-4K it slightly drones in gear 5/6

No, that is not what is meant. The WRX J-pipe is another name for the downpipe. A resonant J-pipe is a relatively new development where a pipe is "T" junctioned where a resonator once was. This pipe then leads to a closed end, often in a shape of a J for space reasons. It has a tuned size & length according to engine size, no. of cylinders & RPM.
It works by quarter wave noise cancellation. ie. The frequency of the resonance divided by 4, with the exhaust pulse reflecting back on itself.
I'm intrigued by it (being both a mechanical & audio engineer (as well as IT & electrical)) as the claim is that it doesn't restrict the flow much.

Still, I don't think that removal of the centre suitcase resonator, only to make & fit a J-pipe, will have any real performance benefit. Sound would likely differ.

Here's one example. Being Drone free.. Well almost J pipes theory and application.

^ exactly that. Science .

But in seriousness it deletes drone and allows more of the crackle when you take your foot off the pedal etc. As the gases pulse inside or something.

In layman terms it's a muffler within a muffler that is connected with a pipe that leads to nowhere. ...okay maybe not the best description. ...

Just listen to what Elmura is saying

[Stanton]

I''m wealy wapped for you I could go into waptures.

This shows how it works!

makes sense
