Hi,
I have a manual R56. Sometimes when i do an upchange, my exhaust pops. It also pops on other occasions, on random.


Is there a way to make it pop when i want it to?

 

Get Alta turbo back exhaust....it'll take care of all that!!

 

Ditto!

 

Replace the mufflers with straight pipes.

But for a great sound get the alta setup!

 

er. thanks guys.... but i was hoping to keep my pipes OEM.

I'm not into loud exhaust notes. I just cannot stand the droning.

 

Can't always have your cake and eat it too danielo...

 

Oh yes you can! I hate the drone... and since the MINI will be a daily driver with an occasional *want* for more power I plan on doing this:



Quiet and civil while driving in traffic... open and powerful when a little more oomph is needed.

 

its not about wanting the cake and eating it when i already have the cake.

The car already pops by itself. I am just wondering how i can control that popping. may it be a particular rev for a gear change or something.

 

Now i could be completely wrong but i think the pop sound you hear is just a back fire. Wikipedia defines it like so

A Back-fire or backfire is an explosion in the intake manifold, carburetor/throttle body or air cleaner of an internal combustion engine. Although an explosion in the engine's exhaust manifold or exhaust system, is often referred to as a backfire.

It goes on further to note

Backfire in an automobile engine typically results from various malfunctions related to the air to fuel ratio. Usually, backfiring occurs in carbureted engines that are running lean where the air fuel mixture has insufficient fuel. ("Running lean" is typically a sign of mal-adjusted carburetors or fuel injection where there is not enough fuel for the amount of air). Afterfire occurs in engines that have an emission system malfunction (air injection system diverter valve), exhaust leak or unburnt fuel in an exhaust system in which the catalytic converter has been removed. When a driver shifts up and lets off the accelerator, the engine has a moment of running rich or with insufficient oxygen. This causes an incomplete burn which causes the fumes to explode in the exhaust system. The leak itself is the most dangerous aspect. Without it, the mixture would cool enough not to explode. A fuel injected engine may backfire if an intake leak is present (causing the engine to run lean), or a fuel injection component such as an air-flow sensor is defective.

So i guess make your car run real rich and every up shift will have a back-fire following it.

 

If running rich is the solution, you should look into adding the Forge BOV. Many have complained of this being the main compromise in having it installed.

 

Do you have a link for this product??

 

BrandonH - I just did a quick google search on Electronic Exhaust Cut Out. There are many different manufacturers to go with.

 

cool thanks. I didn't know what it was and all i saw was otp. if you pop something like that in a search engine it sends you to an illiteracy web site automatically

 

VERY ilegal in CA if you care ....

 

Actually it's QTP (Quick Time Performance). I recognize it b/c I used to have one by that company on my Camaro. After a while the gears developed slop and it wouldn't close completely. Of course, I got that about 4 years ago, so maybe they've redesigned components since then.

Until it started leaking I loved it.

 

Everything is illegal in CA!

I have no idea as to the quality of QTP, that's just the first image that showed up in a search.
