Can the 'burble' be buried?

LOL the burble is computer controlled. i have never heard something so ridiculous! it is caused by the baffle design in the mufflers. it is intentional from the factory, but it is definitly NOT caused by some sort of ecu programming. if it WAS caused by the ecu, then that would mean that when you let off the gas, the computer would tell the motor to run rich and that would cause the popping/backfire. why would mini do that? that would hurt fuel economy.
it sometimes amazes me what people will believe. change your exhaust system and your popping will go away. it will be louder, but it will go away. you can also use some autozone mufflers too ( cheap quiet bad boys) and it will go away.

I notice that my burble changes with the way that I drive. When I went to the Dragon, I did 900-some miles on the highway and then spent 3-4 days doing hard driving on the surrounding small roads. The pop-pop-pop after a strong rev was very pronounced on the first few days and then started to settle down. It also re-appeared when I got home (after another 900 mile highway/cruise-control trip) for a few days whenever I got agressive. After a few days of around-town driving, the pops subsided (didn't disappear, but weren't there as often).
I'm wondering if the ECU learns what highway driving is like and the pops increase with hard driving after several hundred miles of cruising. Maybe you should drive your car like a bat out of heck all the time and the pops will subside!![Smilie](https://www.northamericanmotoring.com/forums/images/smilies/smile.gif)
Just a thought.

Now, back to the subject at hand...I'm pretty sure I've read a number of threads about the burble that have specifically mentioned the cause WAS in fact introduced by MINI as a 'throw-back' or 'tribute' to the old British racing cars. And, it is caused by injecting un-burnt fuel into the exhaust, and yes, it does minimally affect the MPG's.
Anyone else recall reading these types of comments/threads?

Cubis inches - Exhaust Burble
[quote=stevecars60]"There is no subsitution for cubic inches"
quote]
I have to agree, cubic inches are "it". My brother drives a Factory Five Racing Coupe with a 521 cubic inch Ford aluminum block racing engine that puts out over 800 HP... runs straight sidepipes on it and it turns heads in the next county when he romps on it. Also is good at blowing all the leaves out of his garage when he backs in!
I do love the high rpm and sound of my Mini (02 - MCS - JCW) but it can't compete...
As far as exhaust "burble" my MCS didn't have a noticeable one when I got it...When I had the JCW upgrade done (first one done by Roadshow in Memphis) it was there... can't say if it was the exhaust change or the programming change for the upgrade. My JCW kit was installed in 03 so if it was programming, it had to be decided on early on...

Take this for what it's worth, as I have never looked fuel trims while slowing down. My understanding on the "burble" is the same for any car, unspent exhaust gases in the exhaust system being burned. Similar to a backfire. On deceleration with high engine load a rich condition is created (can also happen between slow shifts) the unused A/F gases are expelled into the exhaust and the heat generated there causes them to ignite. Normal under all conditions I know of. The resonance sound is drastically effected by the exhaust design. For example my cobra was rather tame until I relieved it of the crimped factory pipes and fitted it with Flowmaster, I know redneck, and Mac Pro-chamber (cat-less). After a good romp she will spit and puke as to say "why the hell did you let off the gas".

Your ID seems appropriate defylogik, since you seem to be very confident that MINI would not build in a rich condition on throttle back off. Ha! I won't argue with all your logic, but I sleep easy at night knowing that the burble is NOT in the OEM mufflers! I have a complete after market exhaust system, with nothing OEM in the path, and my car burbles and barks like a mad dog. Incredibly loud and obnoxious, there's no doubt unburned fuel is entering the header on throttle back and exploding in there.

When you can show me a 400 HP 370 ft.lbs MINI that is easy to drive for a 16 yr old and will have no major problems for 200K miles, maybe I'll think about considering the possible validity of what you just said. ![Grin](https://www.northamericanmotoring.com/forums/images/smilies/grin.gif)

burble? what burble?
I've owned my '06 MCS from new for 3 months now, and have not heard anything even remotely resembling a burble, burp, rumble or anything else under idle, accelaration, decelaration, or anything in between. The car has been quiet as a door mouse all along.
Was there a 'burble' option and I missed it?

Since I had the JCW cat back exhaust installed to my MCS 05, the burble seems to be disappear
(actually, the JCW makes my MCS to be much more quiet than stock
).
The burble is still there, but very hard to notice, now instead of "Pop" sounds, it sounds like "Thump"...
Maybe a JCW cat back can resolve your problem?
I personally love the burble a lot though.

For those wanting "all hell breaking loose" burble: install a Megan race header with test pipe!

Try driving behind other mod-ed Minis, you will hear the burble.

Well, not to join any sides, but I'm a burble fan. @ 10K now in my '05 MCS, I would hate to motor around without it. Plus I enjoy the looks and revs I get from cholos in their civics looking for a race at every stop-light. I can understand, though as bings, langs and or any other kind of loose sounds can easily annoy me.

Seriously, though, my car makes no such sound. I've driven it under all conditions described herein (as stock) and no burble.
Yes, even with the radio turned down...

I'm still in "wtf, I just shot someone with my MINI" burble mode--and loving it!
