what makes the exhaust burble and pop?

 

it was introduced in 2005 model cars in year 2004...

understand MINI USA came out with a document explaining it is intentional because some people thought it was 'wrong'.

However it is accomplished it was engineered to do it.

 

In one of the other exhaust threads around here it says the MINI engineered the burble into the MINI. The ECU cuts the fuel immediately after you let off the throttle for a sec to create this burble effect. Correct me if I am wrong?

 

Its MINIs way of trying to be "cool" by imitating the burble from muscle cars with unspent gasses in the headers. Some ppl think its "cool". I would think the vast majority of average drivers just find it annoying.

 

i <3 burble.

British sports cars have always burbled. Triumphs did it, MGs did it, Healeys did it better than any other machine ever made, TVRs did it irregularly and cracked their fiberglass, Turners did it with MG engines and hand made bodies, Elvas Couriers did it and leaked water everywhere when it rained, Jaguars did it expensively, Loti did it and their wispy tube frames shuddered and writhed, Minis did it while whipping around corners on their outside wheels scaring the drivers and the guys in the Ford Consuls they were passing at the same time.

It's what British sports cars sound like. American muscle cars rumble, British sports cars burble on overrun, Italian sports cars snarl and sound like ripping satin, German sports cars clatter and fuss and sound very mechanical.

If you don't care for the sound, you could always buy a Japanese car. They either hiss or sound like a bee farting in a can.

 

All I know is when I did the One-Ball exhaust mod (cutting out the resonator) I got a lot more burble . . .and it is awesome.

 

Bravo!

I Love the burble!!!

 

Actually.... the original Classic Mini's would burble and that's what they "designed" it after. That was another way of MINI incorporating the classic's in the new design... Not at all american muscle, like someone else said, american muscle rumbles.. and can only go fast in a straight line, but thats besides the point... KNOW YOUR ROOTS!

 

The burbles and pops (especially letting off in 2nd) are like a symphony. I actually turn off the stereo to hear it. Cool or not I love it!

 

Having owned all of the above, I'm inclined to agree. My MGA had a nice street cam in it and an aftermarket exhaust and sounded really sweet. And my wife's Healey - what a great car, and it sounded great, too! (But I still think an XKE with an Abarth exhaust is the best sounding car I ever heard.)

Love those burbles in my '05 MINI! Especially since I installed the Milltek.

FWIW, someone said (Andy maybe?) that there's something the '05s do with the timing when you let off the gas that causes the burbles. I don't remember the details. I just love the sound!

 

BahHumbug Chow. I love the burble
It is BMWs way of trying to keep the spirit of the old Minis alive in the new

 

Ditto

 

So is this the reason? or is there something else??? It isn't because of the exhaust I know that..

Is there any way to get a pre '04 mini to "burble?" I want to burble

 

According to Kaelaria (sorry - I said earlier that I thought it was Andy), it has to do with the timing: See the thread "Does the UUC exhaust do the 05 MCS tailpipe burble?"

cool thanks!

 

i just picked up my 06 MCS manual and it burbles a LOT more than my wife's 05 MCSa...and i like it!

 

Let's not generalize - that's never a good idea, with cars or people. Plenty of Italian and German cars burble, too. And it's "ripping silk." (Satin is the cheap stuff.) I first heard that expression used to describe the sound of a (British) Jaguar C-Type's straight-six at speed.

 

Only Ferraris sound like ripping silk. Other Italian cars sound like ripping satin.

And desmo Ducatis sound like all of the precision machinery in the world orgasming at the same moment.

 

In 1984 my brother got a new VW GTI. Very cool for its time.
It had a burble, we called it bubble back, and is caused by backpressure through the exhaust. We loved it then, and love it now. Car wouldn't be the same without it.

 

Back to an earlier question, how do you get the "burble" effect in an earlier MCS (2003)?
I drove an '05 and enjoyed the sound effects.

 

i'm getting an 02 MCS, and am hoping that i can get the burble

 

According to Miniusa:

THE CRACKLING NOISE.
When motoring in your convertible, you’ll probably hear an aggressive sort of crackling or popping noise coming from the exhaust. That’s actually been built in on purpose. Back in the day, the classic rally Minis made that type of sound as they raced through Europe. We thought it was only fitting to keep it.
