X3 and 2012 C coming soon
Nice work Gokalp! Impressive. Don't let the AMG guys see this.
Thanks for the insight...or something.
why is everything looks on the MB's forums? you guys want a 3.0 or a 3.5 motor to pull enough air through the intakes and create enough back pressure to warrant 4 channels of back end airflow? all your really doing is spending 2k to make your car slower, have virtually zero launch capabilities and look ridiculous (well i agree the amg quad look amazing but not on a virtually stock C.) will 6.3 and amg stickers be the next mod? if you want that quad exhaust to at least be effective, first you need to think from the front end...headers, down pipes, bigger TB, cams, otherwise all the decent low end torque these 3.0 and 3.5 motors make...gonzo.

Hi,
Sorry for the very late reply, yes I do have some picture, and made a sound recording.
Car is original a W204 180K Avantgarde AMG package, so it is a four cilinder machine. This mod works also fine on a 200K or 6 cylinder machine, the 6 sound beter as I said before.
Limits on the picture size, at this forum but it give you an idea.
As you can see, one original pipe from the engine had to be split into a Y split. When this is done, test have to be done to see if the left and right have the same amount of exhaust gas. If not the Y split needs to be adjusted.
Bare in mind, this is a original C63 spare part exhaust, I had to get a C63 VIN to get it. The replica exhaust, as far as I understood, don't give the same "sound" as the original one.
And ... there is no problem with the warranty, as the parts are original, and build in by a dealer.
Cheers,
Gokalp

Not my style, but even the AMG badge looks fine. You do with your car as you wish, I say, as long as you don't put a "C63" in the back, right?
Sound clip as claimed?

I'm an exhaust mod ignoramus. Will switching out just the tips affect (deepen) the exhaust note at all? Or is muffler and tip modification the only option for that effect?
I don't particularly want to change out the muffler, as my dealer probably will be a pain the the rear end when it comes to warranty issues, and I don't think the C300 would benefit much from any decrease in back pressure and increased airflow. I could be wrong, I guess.
What d'you guys think: how would no engine mod and just a muffler mod on a C300 affect the performance?

Guys,
Tip design plays an important role in sound. Many manufacturers overlook this, however it is a critical part of sound design and is approched by REMUS with this technique:
The red part in this diagram represents the sound deadening material. As you can see, it is also present in the tips. They are perforated and packed with steel wool. This helps prevent and eliminate resonance and drone at highway speeds.
Now to actual performance gains. A general rule of thumb is this, a car OEM exhaust will restrict the engine's performance by around 10%. This is a rule of thumb, remember, this will vary depending on your engine format, turbo, supercharged, N/A, etc.
To make a long story short, backpressure is an enemy, you do not need it, what you need is exhaust velocity. The error that most tuners do is oversize the piping on most applications but they use crush bends. Remus uses mandrel bends and reduces backpressure but keeps a proper exhaust velocity by using a suitable exhaust piping size.

Hi,
To answer some questions:
-AMG logo, well, it looks nice for me.
-C63 logo, no don't over do it (yet)
-The quad tips, well I checked out the tips for dual it would have cost me 836 Euro ex tax.
-To much for single to quad! Yes, indeed it is. It's a hobby.
See pictures of the tips, the exhaust system is set behind the cat. Let say from the middel of the car to the rear end.
As for the driving experiance, I do feel a diffrence in driving, it's better. There is a BHP increase, but how much I don't know, and is not really the reason for the mod.
Cheers,
Gokalp

[QUOTE=REMUS;2864897]Guys,
To make a long story short, backpressure is an enemy, you do not need it, QUOTE]
Some have given good reason why you do need some backpressure. If you reduce backpressure too much you can lose low-end torque. I have actually experienced this using improperly tuned exhaust systems.
Here is a great explanation about why some backpressure is necessary:

Hi Miropower99,
To correct you, the dual cost around 800 Euro, so the ones the 6 cylinder machines have. The quad is unknow to me!
And indeed, the backpressure is needed, that was also a big concern during the build.

Gokalp

A catalyser, for street usage, will provide MORE then enough backpressure to keep the needed torque at low RPM. Switching out you OEM muffler for a straight through design can only be beneficial in terms of TQ and HP. If we were talking about removing catalysers, I would definately agree with what you said.

I've got all that **** on my car plus some and it still says C300 4Matic on the back. Either Debadge completely or leave it on there but don't start getting a head like you are driving a fast car because you have 4 pipes. Mine is a show car, thats how it will stay. Frankly, w/a 4 banger, so is yours. Once you all manage to get your diffuser and quads on don't think that entitles u2 AMG badges. Thats why

Don't worry. I don't wear fake Rolexes, and I won't ride fake C63s. I'm more of a debadge-everything-make-it-look-clean kinda guy. But that car isn't mine. It's HIS car.
