If you're willing to spend the $$$, the easiest way to run a "true dual" would be to swap out the spare tire well/trunk area with the setup for the C55.
Weidermann (one of the OG members) had a Midnight Blue C32 that he swapped out the C32 exhaust with a C55 exhaust, which required having to change the tire well area (placed differently on a C55 due to the exhaust). I don't remember how much he spent, but if you do a search for the threads he created, I'm sure you'll find the info. I do remember that it was a pretty costly job, however, I'm not sure how much of that was in replacing the entire trunk area vs. the exhaust itself.
He posted mostly in the C32/C55 forum.

Actually, just read his posting a few days ago. Very impressive what he did, and I'm sure it was bigtime bucks. The thing with the non- C55 models is that the spare tire well is not centered, but shifted more towards the right side of the car, making installing a dual exhaust system a nearly impossible feat. So, what Weidermann did was replace his spare tire well with the C55, which is centered. Which then allows space for an OEM C55 dual exhaust setup.
Things to note:
- The spare tire, tools, equipement, tire well cover all need to be replaced, as the non C55 models' equipment do not fit in the C55's well.
- Replacing the spare tire well is not a painful as it sounds. The W203's basically have a molded plastic tub that sits on top of the frame rails. Removing/installing, is just a bit more than unbolting the old and bolting the new one in. I'm sure there's more to it, but unlike other cars, who's spare tire well/trunk floor is steel, and welded to the body, the W203's is just basically a plastic tub.
Search for his posting. It's really remarkable. It may be in the C32/C55 picture sticky thread, but not sure.

A "true dual" piped exhaust means that the piping flows directly from headers, to down pipe, to cat, (to 2nd cat if applicable), to resonator, to muffler and out. With a V6 model, this is achievable. With the m271 engine, there is only 1 set of headers (as supposed to 2 on the v6 models).
So, doing Y piping before the muffler exits would probably be more of a detriment to your car than a "help" as far as performance is concerned. Basically, instead of the exhaust flow from the primary exhaust/headers going straight through 1 pipe, you'd end up splitting the air flow prior to the mufflers, which isn't ideal.

BTW, I was thinking of doing this (quad exhaust) with mine, mostly for the rear to look symmetrical, but cost is way too much. Besides, I can admit there'd be something wrong with having 1 exhaust outlet for each cylinder on my car (M271). Maybe not as bad as the Civic I seen a few weeks ago with quad 3 inch exhausts exiting out from the center of his car, C6 Corvette style
Don't know if it's worth putting in dual AMG exhaust tips on the left side, a la 2007 C230 style, and then throwing on similar tips but fake on the right side.
Saw a posting that had some setups where there were dual tipped on the left, and then a pipe was snaked between the spare tire well and the rear bumper over to the right side. Not sure how this bodes for back pressure, or whether the pipe was solid and fake.
Here's a link for one of them:

Not sure how much these would cost.

You mean, like mine?...LOL. I don't have true dual and it's not ideal for a 4 cylinder engine to have a true dual anyway. I had it custom done from AAA Exhaust in L.A. Unless there is a shop that you KNOW does quality work, I'd hesitate as well. Thing is, it was MUCH less expensive than I thought it would be.

But with a 200K, I hope you realize that you won't have a "true dual" as compared to the v6 models.

Thanks. I already have removed the OEM centre cat and replaced with 3-in-line mufflers before the Y pipe. My reason for fitting the C55 tyre wheel well is to get a better fit as currently the pipework is tight and unsightly wrapped round the current W203 wheel well. Would fitting 2 extra c55 boxes (1 either side) to attach quad pipes too still restrict air flow? As i am also hoping to reduce the level of noise (its legal but loud) in the current system set-up.
If you already have 3-in-line mufflers before the Y, the 2 extra mufflers would definitely decrease the sound, but also might be too much restriction for the airflow.
Ultimately though, changing the piping from as straight through (1 pipe) design to a Y pipe before the muffler exits is not the most ideal setup for an i4.
Ideally, you want the piping to be as straight through from the headers all the way to the exit tip, especially on force induced 4 cylinder engines. That why a "true dual" on a v6 is great because the piping is a straight through design from the headers all the way to the exit on both sides.
Basically, I'm trying to clarify for those who don't understand the meaning of "true dual" (so please don't think I'm saying that you don't comprehend). Once you have a Y split into 2 exhaust sides, it's not really a "true dual" because the piping starts from 1 pipe. In a "true dual" setup, the piping leads straight (relatively speaking) from the engine where the headers are to the exhaust exits. For those that don't understand, v6's have 2 sets of headers (3 cylinders per side - true dual would give each set its own piping) and i4's have 1 set of headers (4 in line). v8's have 2 sets of headers (4 cylinders per side)...etc, etc, etc...

I would suggest that you cut the bumper to match the diffuser and center the tips to finish the dual look!
Yep agree..I personally would not cover the white parts - just get them cut out right so all you can see is the diffuser cut-outs.
Can't understand why you would want to cover it when it takes few seconds to cut away the bumper cut-outs to get a nice
clean job!
clean job!
...cutout the bumper and make the tips fit to the diffuser. it looks retarded and doesn't do the diffuser justice.
FrankW recommended cutting the bumper so the openings are the same, and reposition the exhausts so they're centered.
I agree...
I agree...
I would recommend you visit a good local exhaust centre…
Except here. Perhaps congratulatory comments were sent via PM.
My previous post was not intended to diss you personally.
Rather, it was merely to suggest that you have your shop size and refit the cutouts and their tips so that the diffuser’s intended visual impact can best be fully realized.

My opinion...still needs some work. Looks like on the top left edge, it's not flush with the white of your bumper. Again this is the case above the right side dual exhausts. And the bumper definitely should be cut to match the diffuser's openings. Again Just MHO.
Otherwise I think it looks really nice on a white car.

It happens some times you just got flagged. It happened to me not on the diffuser but on something else I ordered from California. I asked why they needed this info and was told they randomly audit packages entering the country and it just happened that it was mine. If this is all it is no worries just go down and they should release the package good luck!
