If you look closely at this image, you'll see what I'm talking about. There appears to be a muffler on either side under the car as with a typical twin exhaust system.me said:
The weird part is that in some of the offical S photos, the car appears to have two large mufflers (silencers) - one on either side of the body - feeding into each of the two exhaust pipes. Can anyone explain that?

Then we see that the gas-cap is not as it seems. Now we find out that the exhaust, does not come truly from the center of the vehicle.
It was this very picture that made me part with my $1000 deposit. The twin mufflers to each side of the rear twin pipes are the biz.BruceK said:

As I understand InsiderMINI's explanation, there are 3 mufflers on the Cooper S, but the final two mufflers mounted on each side of the car are NOT separate and equal (like with a V8), instead they are plumbed in sequence so that all the exhaust gases flow through the 1st muffler, then the 2nd muffler, and finally all the exhaust gases flow through the 3rd muffler before exiting the twin exhaust tips.Basil said:

If they're not mufflers what are they ?. I hope the "S" still has some integrity left by the time we all get ours!
Ahh..... an excellent voice of reason.....yes I was just winging before. Must be the pome in me.....my apologise. Roll on mid 2002.....noahe said:So... Can anyone explain the setup? The twin tips are to look cool, because the diameter of the feeder pipe is no larger than the tail pipe. Essentially the Cooper S has three smaller cans and the Cooper has one large one.
I suspect that the the three shapes are as follows: A resonator to give the Cooper S it's described more distinctive tone and to engineer the backpressure. Then two sequential low-restriction mufflers for good flow, and between the two of them, adequate noise reduction. There's not really much point in splitting the exhaust in two for an inline engine.
There is another less cool reason of course. A single muffler didn't fit around the battery box. At any rate, it seems like a lot of plumbing to replace when it goes.
I for one don't let these things get me down of course. It seems a wonderful car. I always expected a car that would ellicit such emotion would be something unattainable, like a Porsche or a Ferrari. I'm just so pleased that I'm going to have a Cooper S with only a little financial stretch, that everything else just gets the volume turned down to me. Bring it on in whatever form the designers can dream of. I'm sure we'll all applaude when we first fire one up.
Blimey, this pulling left problem is a lot more serious than I thought.......94SwiftGT said:This is the way the exhaust is run on a cooper.
The exhaust on the S should be routed basically the same way. I would expect the exhaust to split at the rear and go to 2 independent mufflers that come together in the center at the tips.
