Smile Twin Exhaust Pipes - A Necessary Technical Addition or Aesthetics?

Hello Everyone

I was just wondering whether the more technical minded amongst you could answer this question of mine - Apologies if it is daft - I am only a lawyer!

Here goes:

I notice that the W164s, even the base model ML350, has twin exhaust pipes.
The older W163s don't have the same feature on the base model (ML320).
Infact only the W163 ML55 has twin exhaust pipes -The ML430 & ML500, both V8s, donot.

Question is: Are twin exhaust pipes an aesthetic addition to the W164 ML350 or do they actually serve a technical purpose?

I look forward to your responses!

Dual exhausts are an important fashion item these days, although they do buy you about 5 extra horses.

On the ML350, they are functional duals with separate pipes off each cylinder bank and dual converters. So it's not just for looks.

I thought they were more of a fashion item myself - Especially on 6-cylinder variants of the ML series.

I note too that more and more 6-cylinder cars from more and more manufacturers sport dual exhausts. (Nissan, Acura, Lexus)

If you look at the older inline 6 Mercedes, you'll note they had twin pipes all the way to the rear. Just the station wagons were 2-into-1 at the rear muffler.

Our E320CDI--another inline 6--has dual exhausts.

I din't see how that helps except to add weight since all of the exhaust is routed through the turbo's turbine before splitting into two paths after passing through the turbo.

Potato Chip, custom canuter valve, low-friction muffler bearings, synthetic turn signal fluid, Hi-Definition Progressive Scan Wiper Blades.
Law-makers are supposed to regulate in the interest of the public as opposed to regulating in the interest of the regulated party.
If it says Pratt and Whitney on the outside it better say Martin Baker on the inside.

Fashion statement and functional feature on the ML350 V6. It's a true dual exhaust system with separate pipes off of each cylinder bank, just like a high performance V8 setup.

You can't even see the exhausts on the E320CDI, as there are no chrome tips.

Most internet pundits these days complain about Mercedes "cheapening" their cars. If that were really the case, invisible dual exhausts might be the first thing to disappear. Makes me think there's a performance advantage.

True, on the CDI the dual pipes are not visible. On the W210 (E320CDI) the pipes were parallel to each other. Smaller CDIs had dual pipes from the last muffler, this could be a pure aesthetic approach but the 320CDI had dual pipes from the turbo (or almost) onwards.

I really don't know how much it is for performance but I'm assuming two pipes allowing the same cross-sectional area in less vertical space under the car compared to a single pipe which would be one technical argument.

I guess the aesthetic one still remains on the diesel too (at full throttle one could see some exhaust coming from both sides?) but it may not be the only reason for two pipes.

Most of the duals one sees today are fake. So called domestics and foreign. A single pipe splits into two right at the rear axel. The manufacturer evens adds a real muffler to fool us. This adds weight and cost in terms of extra pipe, hangers, muffler and chrome tip and does nothing for performance. I wonder how much fuel is wasted collectively over the years with all the cars on the planet carrying this dumb dead weight? Hummm. I would also imagine that those two rear most mufflers fail prematurely as well because the moisture wouldn't dry out on short trips with the exhaust heat divided between two zones. Now the owner has to pay that penalty as well. I had a factory representative admit this sham to me at a car show a few years back. Purely to fool the owner and the restuvus. And can't you imagine human nature. The owner thinking he, or she, has a performance car will perhaps drive a bit more aggressively. Hence more fuel waste to alas, no avail.

The more important performance exhaust is the exhaust header design. If it is a four into two into one then that is a preferred arrangement for efficiency and performance.
I have a C230 with the 16 valve 2.3 with said style. The car is "fast" enough. A true performance system. One complete and separate exhaust system for four cylinders. HAH! As good as it gets y'all.

Most of the front wheel drive dual exhausts on V6's and inline 4's are fake duals.

But here we are talking MB's and with late model MB's the dual exhaust systems are functional/true duals, see the new C-class, ML, SL, GL, R-class, E-class, S-class as real examples.

MB sees it correctly; a must-have styling and functional feature for all of their new high-end vehicles.
