Hey everyone, for a while I have thought that my vehicle is way to quiet, and I want to make it a little louder. I know it is designed that way for a nice, enjoyable ride. I don't want it to sound like some civic with a can, but just a good tone and loud sound. After reading a lot of threads I have learned that the resonator, and muffler on the exhaust system is what quiets the exhaust down the most. Wondering if removing the resonator, and muffler, then doing straight pipe from there would sound a lot better? Would this create any problems, such as heat issues?
I think the rear would look a little strange with just straight pipe though, so I will likely put a good exhaust tip on. Maybe even use the original tip as it looks really good on the vehicle. My brother suggested replacing the resonator with a flowmaster unit, instead of just removing it. He told me that the flowmasters add a good tone, and are designed to prevent air from going back into the exhaust system, which increases performance some. Not sure if that is true, or not? I also learned from searching that our supercharged vehicles require some backpressure. Removing the resonator completely would lessen some of the pressure, so adding a flowmaster should bring it back up.
Now for the supercharger. I have read that it is equiped with a silencer, and silencer equalization box. Is this something can be easily removed. By "easily", I don't mean completely simple, such as removing a few bolts, but something that should be able to be accomplished by a beginner/novice to engine work with some instructions. Has anyone removed the silencer on one of these M111 engines that is active on this forum? I would like to know how much louder the supercharger is after the work is done. I would rather not be annoyed by an extremely loud noise. Hoping that it just makes the supercharger slightly louder.
Appreciate any comments, advise, or experience with this matter.
Thanks,
Matt G.

As for the exhaust system I would simply trade in for a Remus kit you'll love it.
and get a S/C ASP pulley it will be loader with the new undersize pulley. Plus you'll have more power.
that is one guy's opinion so keep searching and you'll find what's best for you and the car.
good luck!
I would rather not spend the money for an entire new exhaust system. That is why I'm planning on just modifying the original exhaust system. I have been thinking about buying the smaller supercharger pulley though. Just not sure if I want to use one, because my supercharger is 96k miles old now, and will probably give out. Wondering about having it rebuilt, but I don't know where, and how much it will cost to do this. The smaller pulley wears out the supercharger a lot faster, doesn't it?
I'm hoping that someone has ran a S/C m111 engine without the exhaust resonator, and muffler, so I can get an idea of how it would sound. By the way, how much is the remus exhaust, and what all does it replace?
More comments appreciated. Especially about removal of the supercharger silencer, and silencer equalization box.
well I know that ASP give you a new core for the S/C.
the exhaust system is the rear axle only you dont need more unless that you want a headers kit on the car too. But rear axle from Remusis the only power gain you will have on the exhaust system. It will go for about 700$ to 800$ cdn. witch is not expensive for the quality.
as for the box on the S/C I have never heard of any removal so I can't help you with that sorry.
Taxi615, thanks for replying again. You are saying that the Remus exhaust only replaces the muffler, correct, or does it also replace the resonator? If you have the Remus exhaust installed on your 02' C230KSC, I would really like to see photographs, and if possible, a sound clip. I'm considering buying the exhaust, but need to see how nice it looks, and how good it sounds first. $700 dollars is kind of on the high side for me though. I work at Wal-mart, and only make about $15,000 a year...
The SC "silencer" requires removing the SC intake to get to it.
Search on mbworld, I posted a pic of it.
I tend to think it's there for a reason, so I left it, and the M111 with pulley is noisy enough. You could get a magnaflow muffler but hard to say what it will sound like. Remus is expensive. If you are on a tight budget, keep an eye open for a used one. They come up once in a while. I got one for $200. You can remove the resonator, muffler shop can cut and weld for maybe 50 bucks.
My car is loud as hell (magnaflow cat, and remus muffler) and I'm thinking of going back to stock exhaust. It was the cat that really changed things.
Already had the Remus.
So far it hasn't got me in trouble, but one advantage is it wakes up brain dead, SUV driving and cell phoning drivers who either aren't paying attention or
in the case of SUV's think they own the road.
I drop a gear, and it gets them looking around, and often moving out of the way.
Deleting the resonator (50 bucks, likely) sourcing a Remus Muffler (700+)
and installing it (50-100) total of about 800-1000, will get you a slightly nicer sound, but for the money, there's better things to spend your money on.
(Suspension, ASP Pulley)
You will be disappointed if you spend a large percentage of your disposable income on a muffler, the car won't go any faster or drive any better.
Get some springs and AMG sway bars and head for the mountains....
that you WILL notice for about 500 out of pocket.
Remember also, that Benz spends a lot trying to insulate you from the outside noise. By the time it sounds good in the cab it's really loud outside.
Even with a Remus muffler you still won't hear much difference from inside the car.
Your video of the driveby sounds pretty good actually.
I need to do the same.
Search on youtube for clips.

I agree that if you dont have the budget then do something else. But getting a loud sound sometimes drives people crazy so keep that in mind but a Remus kit will be nice and will sound nice and wont bother you in the car nor drivers around you. I wouldn't push you into deleting the res. (loud).
ASP would be a real good mod and a flashing of the ECU.
I have nothing to show you I'm all doing my stuff this winter.
suspension upgrades are always magical you'll love the driving.
Just dont forget to do you things gradually and in an intelligent way (HP=sus. and braking.)
so if you do have a project in mind do it the right way you'll love that car more and it will love you back!
don't mess with the s/c unless you know what your doing ... if not it could lead to costly repairs. my previous car was a stage 3 turbo wrx. It was boosting very high psi and the maintenence was troublesome. It got very tiring so I decided to move towards some luxery. I would leave the car as it is but to each their own. I thought about an exhaust but i like to keep under the radar and for the minimal performance gains i'd rather put the money into cosmetic upgrades and have some ladies notice the car .. not riceboys

Mostly I have been keeping my thoughts in the handling, and cosmetic area. I think that the car should be a little louder though. Kind of as loud, as it is fast, if that makes any sense... I did want to make the supercharger slightly louder, but no one seems to know if the silencer is there for any other reasons than to just silence it up. I wouldn't want to go, and mess anything up. I had just figured it would be a simple procedure to remove the silencer, and have no bad side effects. Maybe, if I just removed the resonator only, and left the stock muffler it wouldn't be too loud, and sound decent. What I want is it to sound good outside the vehicle. Not sound loud for myself inside the vehicle.

The handling of the car is already really good. I could only amagine how responsive, and stable the handling would be after sway bar/suspension upgrade. One thing that sucks is there is really no where for me to take the car around here with some nice turns. When I go to work I always take a side road with nice turns, but the speed limit is 30mph. Not much fun in that, and I don't want any speeding tickets...

Exactly. That is why I'm looking for the cheapest way to get a little more sound out of the exhaust, while at the same time keeping it a good tone.

That is how I want it to be. Loud from the outside of the vehicle, but not annoying on the inside.
