Ain't beans.... Sorry for starting that rumor.

One thing I noticed is you are not winding out the engine enough.

I'm wondering if you have some small stones laying on top of the mufflers or the silver plate under the battery box. Lay under the back of your car & with the exhaust cool smack the exhaust & see if you can duplicate that pinging sound.

Other than that I have nothing.

 

Listening I couldn't hear a "ping" noise. There was a loud "thunk" which I think was a gear change. Is there is specific point in the recording to listen to to hear the sound you are referencing? (Yes, it's slow at the office today. )

 

Okay that is what I thought was a gear shift. If it isn't and it's coming from the back I'm gonna lean toward loose suspension parts unless you have tire/spare/tools in the back that might be loose. If they hit any part of the frame they will make an noticeable noise.

 

I still think you need to take your meds.

 

Did you recently start using Q-tips?

 

Have your guy check to see of all the exhaust hanger's are OK..... Just wondering if maybe one of the rubber isolators is missing and it's moving around too much....?

 

OK I'll tell you Babs secret for noises that bug her. Run the wee outa it & turn up the radio! :smilewinkgrin:

 

I agree with Metalman if it is not the burble have them check the exhaust straps if you live in a snow area where they use salt they get eaten up pretty bad.

 

Check your engine mount, too. I had to adjust my exhaust hangers after I replaced a failed engine mount. That may be moving enough to bang the exhaust on something.

With only 11K on his car and Fungo taking a nap all winter, MM won't have these problems for, say 20 more years or so. :lol:

Sounds like the "burble", but two things:
1. When the car is cold, it doesn't burble as much, so less "pop pop pop" until the catalytic converter lights off. Once she warms up and the cat is active, the "burble" is more pronounced. I've got a straight-back exhaust so the effect is magnified, I swear I can tell what the outside temperature (and engine temperature) is just by exhaust note.
2. Your rusted-out exhaust is magnifying the effect.

The outside of your pipes will typically show rust but they hold up well, it's the resonators that quit early. And a non-stock exhaust is also cheaper than OE - WIN!

Good luck!

 

It has been my experience that cars that do not get driven much go through their pipes at an accelerated rate, hence Kitty exhaust being crispy. Kitty be very careful what you pick for an exhaust. The back of a MINI is like an echo chamber & what sounds cool for a while can drive you buggy on a long trip. That being said I love my JCW exhaust. I'd recommend one, but they are getting hard to find for the R53.

Chuck I know you have plans for a new custom SS exhaust. Might be a timely mod. :wink:

 

IMHO the JCW exhaust is one of the nicest out there. Great choice! I love mine.
