need advice after installing my milltek headers and jcw exhaust the back fire of my cooper s got worst. it drives me nuts sounds like a popcorn machine when you let go of the gas ......whats the best solution? thanks

 

better learn to deal with it, your not gonna get rid of it unless you put some very quiet mufflers on it.

the poping sound its just going to happen, until you muffle the sound. every car does it, you just cant hear it becasue the exhaust systems muffle it.

Most people like the popping sound after chaning out the header and putting an exhaust on, it sounds meaner.

 

you didn't do much research before you bought your car and had upgrades installed. It's common knowledge the mcs gets that great popping sound right off the lot and it's also common knowledge the upgrade of the exhaust you got does the same. What were you thinking?

You get rid of it by buying the standard Cooper. Mine doesn't pop at all. Wished it did though.

 

I believe on the MiniUSA forums, it was determined that the popping sound was 'engineered' into the Mini, because the old Mini's used to do it, and that it is a 'feature'.

 

wow
this is a first... i have never seen anyone complaining about the popping noise!
everyone including me seems to like it...

but in any case... like (not-so-rednwhitecooper) said is very hard unless you put on some very quiet mufflers... and i think the price for all of it will be alot more than to stand the noise...

good luck with that
haha

 

That's just the sound of your Mini grumbling when it has to slow down...

 

But it won't eliminate it.
But it's just a fact of engine dynamics. When I first got my mustang, it has 18" glasspacks. Downshifting into second sounded like shotguns going off! I would set off car alarms, and my Mom knew when I was coming buy a minute or so before I got to her house.

I'll gladly take your pipe and header off your hands. I wish mine was louder.

 

I think you could "fix" it with a good tune. You'd need access to the entire fuel map though, something most of our bandaid tuning options can't do.

 

god i love that sound! you are crazy

 

AMEN BROTHER PREACH ON! I Wish MIB would pop and burble. But when I take the corners I forget about the pop and burble!

 

Yep old Mini's with a leaking exhaust popped & farted a lot. I'm just glad the oil leaks, barking syncros & intermintent electrical system weren't engineered into our new MINI's. I personally like the popping though.

Not true! My MC burbles plenty. Of course, I didn't hear it much until I started trying aftermarket exhausts. I recently removed the resonator from my RSpeed catback - even better.

 

not sure if this is true but i heard the dealer can program the popping out if you dont like it...

 

I love it, it's so addicting.

 

There is one solution, send me your millteak header and jcw exhaust and i'll send you my stock header and exhaust. PM me for details

 

There is a huge diff. between 05 and 04 popping sound. I have a 04 and I want to have more of that sound.. is it possible ? and what is the difference of 05's that makes it?

 

So has anyone else suggested, just STAY on the GAS?

 

its hard to believe a guy with a ferrari would complain about a bit of engine noise!

hell, if i had a ferrari, id have it running open header like a race car just to hear that engine pur

 

Me too . There's nothing like the sound of a Ferrari with an exhaust (or stock for that matter).

The MCS makes some of the sweetest sounds. The supercharger whine and the exhaust burble make it completely unique to any other car I've heard. I love to be sitting on the side of the road and hear a MINI coming hard up through Deals Gap. You know it's a MINI before you ever see it.

 

Or earplugs
Like most others here I LOVE the burbble, pop burbble. I've got a magnaflow & soon I'll have a header too. Can't get enough of the sound.

Go for the stock exhaust. Either get rid of the Miltek or aquire an additional resonator. That should calm it down, but won't eliminate it. Its one of MINI's charms

 

I wish my 03 had that great burble! I want a Milltek...hmmm.....

 

Once you get to drive it awhile,you should start to enjoy it.
