I bought a second hand R53. It has a magnaflow catback and on decel, it pops and cracks, annoyingly. More irritating is, it does absolutely nothing for a SCed engine. Not sure if it's a tune it just a function of the catback.

So, any idea of how to get rid of the pops/crackles.

 

Most of us consider, that a feature of R53s.

The Magnaflow exhaust is, going to amplify it. Check to see if you have a resonator. If not, having a local exhaust shop install one (don't think Magnaflow has a resonated option, so it would be a custom job). Or pull it, and install something tamer. Stock exhaust will be the quietest, but it still pops on decel. JCW exhaust is still pretty quiet.

 

Pre 2005, Magnaflow or other performance exhaust, especially non-resonated as posted above. 2005 and later, factory tune amplified by your Magniflow. Pops and crackles were added to the facelift models, but can be eliminated with an aftermarket tune.

 

It's in the factory tune, putting an exhaust on the car just makes it louder as you can barely hear it with a stock exhaust. I honestly like it on mine (full exhaust). The only way to get rid of it is to get the car tuned with it removed.

 

This is what I run. 4-2-1 header, and no resonator. Very tame, until you get on it that is. Pop's and crackles literally sound llike popcorn. Its as if the JCW catback takes the loud edge off.

I would love loud pops and bangs, but my wife would kill me. What she doesn't know is I'm putting the converter on v-bands shortly

 

If you want to get rid of those sounds, you'll have to put the stocker exhaust back on.

 

I think you got the wrong car. Lol

 

Thanks for the feedback everyone. Looks like I'll have to suffer, along with everyone else, everytime I take the car out until it irritates me enough to get a tune or find a stock exhaust.

Just annoying since I'm not 19 years old and every modified VW/BMW in the world has that obnoxious tune on their car.

 

Just to be clear, it's not the tune. The stock R53 program in the ECU of any S will produce the burbles to which you refer with pretty much any non-stock exhaust system. Don't tromp on it and then engine brake down long hills and it won't be so bad. You can control it pretty easily with your right foot.

 

So why do some tuners ask you if you want to keep it or remove it when doing a custom tune on your R53?

 

The pops and burbles were added starting with the 2005 model year cars. Here's the "solution" from the service bulletin released by MINI due to customer complaints of backfiring:

"Measure: Do not attempt to repair or replace any parts, this is not a failure of any driveline components. The acoustic feedback is a standard feature of the 2005 Model Year Cooper S vehicle produced as of 7/2004. This feature cannot be retrofitted to the previous model year vehicles."

I've read a few ECU tuning threads where the pops and burbles were removed by an aftermarket tune, so that should be an option.

 

because they can remove it, it was added in the tune and any car including pre facelift can have it added.

mpps cable is cheap, so is a tune from adrian if you want it removed or made louder

 

I know, my question was for the guy saying that it wasn't the tune, when it is.

 

My bad! My experience is with two R53 cars, both pre facelift. Neither made the burble until aftermarket exhausts were added; neither had any altered program tune. Didn't realize that they artificially induced this in post-facelift models. I stand corrected!

 

i have a full uncut factory exhaust with 66,xxx miles on it and in great condition. I’d sell it but can’t ship it

 

YES...you CAN....tune the deceleration popping out, if the person with the computer knows what he or she knows what they are doing..!

I've tuned it out of bike engines for years. A car engine tuning is NO different. It's just a pain in the *** with the R53 computer.

he's correct , I had adriancl completely remove my pops n crackles , allllllllllll though I get an occasional pop between shifts it does not pop and backfire on decel .ugh I hate that.

 

Wish you were close. I have a JCW cat back exhaust that I would gladly trade you. It will fix your issue.

 

My brand new '06 R53 with stock everything burbled from the beginning. My second '06 R53 with JCW exhaust also does it, as expected. Noise level seems about the same.

 

MrBlah,

I have a 2006 stock JCW (3AL)... can you burn in a pre 2005 JCW factory tune that does NOT have the Pops/Burbles so that the check-sum comes up correctly at smog check??

 

You can't change the fuel and ignition maps without calculating a new checksum. If they are checking the checksum value it will be different. I have added more pops and burbles, I've never tried reducing them, but it's probably the same trailing ignition map.

 

Thanks for getting back here
understood

I should have been more clear

Is there a Factory R53 JCW map that does not have pops/burbles from previous year R53 JCW-kitted cars?

Is that map available?

If so… can it be burned into a 2006 factory 3AL car ?

If so, Will it function well with the 2006 3AL cars… and checksum-verify?

Thank you for sharing your expertise here … much appreciated !!

 

I don't know the answer to your questions.

however, you can have the pops tuned out. Adrian on the site here can do it I'm sure.

while you are at it you can have him change whatever else you want to tweak.

plus it will be a tune to your car, so prob better than a generic tune

 

No the factory jcw tune has burbles.

You could just buy another ECU with a tune that doesn't have the burbles and swap it after you get your emissions test. Adrian could set up the tune and I could flash it on to ECU with an immobilizer bypass so it'll work in any car
