Now, I have driven/heard multiple 63 amg cars before (all models)
be them, used w 25k miles, or next to new w 100mi - 2000mi....

I am in another state, so really have no basis for comparison at the moment,
but just picked up my 07 e63 w 30k miles.... sold e55 to friend....
anyways, the car was a one-owner, lady driven, 100% service records at dealership, all stock never modified car, etc

The exhaust just doesn't seem "all there"
Of course w me, sometimes I tend to overanalyze and "create" problems in my brain and obsess over these....
It's louder than my 55 stock was, and maybe I was a bit too hyped up for the car and had too high of expectations on the louder exhaust note,
but is it possible to have this happen (maybe because of "weak" driving style, etc?)
Is there anything could be added/removed to muffle exhaust (maybe she didn't like it??)
Secondly, does the "sneaky ECU reset" work on 63's? I did it......
Car looks & drives great, brakes, engine, etc.....
I am hoping my driving style will re-learn the tranny/ecu and also maybe cause exhaust to change -- w time (from new to 30k miles) does the exhaust typically stay the same, get louder, or soften up?

If I brought it to a muffler shop or dealer, what could I have them look at?
---For instance, when the car is running, I can stick my head by the exhaust tips and cannot really tell the car is even running, it is that quiet at idle. Even at 6000rpm I feel there should be more presence on the naturally aspirated motor......

Had a PPI done by independent..... no CEL lights, PERFECT service history (no mechanical problems) etc.....
Thanks for any advice....

In terms of the sneaky ECU reset, that should work on almost all cars that are drive by wire, including yours, but the only way to be sure is try it and see.

A popular option to give the exhaust a more satisfying tone without going over the top is a resonator delete, if you go to a muffler shop they should be able to do this easily, normally for less than or around $100, and most people agree that it is one of the best value for money mods you can do in terms of sound.

Enjoy your car.

The TCU adjusts fairly quickly. AMG said one lap of a track will adjust the tranny.

As for exhaust, sounds great to me.

Except when law enforcement is around.

Got in trouble with some low traction and chirping tires. "The man" did have probable cause, but damn, a Ford SHO would have been quieter.

I do plan on doing the Resonator delete, and possibly more to the exhaust -- however before I start "tearing" into the mechanicals, I would like to make sure my car is acting correctly, starting with a good Base/Foundation (so to speak)

And for some reason, this car doesn't remind me of all the other 63's I have been around (purely memory at this point)
I really don't know what level or basis to use for any type of comparison......
Thanks again

If its really bothering you I would go to a dealership that has an E63 and ask them if you can compare the exhaust sounds. Just have both cars running and walk back and forth see if either is louder, although I would imagine that its all in your head... no offense

Just do a resonator delete. Cheap, easy, and makes the exhaust more alive.

I did the resonator delete on my 63 and initially was quite pleased until I drove my father's SL63 and new C63! The exhaust note on both cars make my car with the resonator delete sound like a hybrid that hasn't started the engine in comparison! I cannot believe how aggressive both cars sound compared to mine, trust me a considerable difference.

Has anyone else noticed this?

jpohl402

Sure have..... the E doesn't compare......

bobgodd

I'm gonna say that is due to different muffler design. The muffler has a big affect on the sound of the car.

Fr33kn63

yeah I had noticed a difference in exhaust notes as well. THats why I went back and changed most of it. Right off the primary cats I went to 3" SS pipes to an X-pipe in the location of the secondary cats(which i deleted) and then straight to the stock mufflers(deleted resonator). Really woke up the exhaust note. I have heard mine somewhat recently next to a stock c63 and think mine sounds more agressive now.

^^^^
Any check engine light - Because of sec. cats delete ?

Timeless

Should only get CELs from primary cat deletes.

eagle_lex

now the guy that can make an E63 sound like the new C63 would have the winning setup in my book! thats the sound that i would be after if i had an E63...

mprsev

Yes, the C63 and SL63 sound uncapped in comparison.

intellilogic

The 09 E and CLS are the same as the C and SL =[ we just missed the boat.

eagle_lex

so the 09 E sounds diffent then the 08 E? wow. that sucks. i love the sound of the new SL and C63.

mprsev

I have to believe there is something we can do to our existing W211 E63 exhaust to rival that of the SL63 and C63 without having to go aftermarket or chop everything off and having the dreaded exhaust drone.

So I did the x-pipe resonator delete and was temporarily happy but there has to be something else. Remove secondary cats?? With this throw a CEL? Will I have emissions problems?

eagle_lex

i agree with you mprsev. im sure there is something that can be done. we just need the MAGIC formula!

Who did the exhaust work for you?

storm

the reasons the SL and C63 sound better and more sporty in exhaust is simple..

mercedes designed them as SPORTS cars, and as such, the SL and C 63 have shorter exhausts pipe distances, the resonators
and mufflers have LESS baffles and sound deadening in them..
and are slightly Smaller all of which make them LOUDER

in the sedans, merc makes the pipes as longer slightly
the resonators and mufflers have more baffles and sound deadening in them.. and are slightly larger which make them QUIETER

a smaller 4x6 muffler with smaller resonator on a sports car, with
shorter tubing, and less baffles and chambers and less sound deadening
material, will sound alot different and louder than

on the same engine, with a sedan with longer pipes, larger 6 x9 muffler
and larger resonator both with more sound deadening material

if you want to make you car sound more like the SL and C 63,
simply get a smaller cat, and bullet resonator, and use a smaller AMG muffler like the C 63

although it will sound more like the SL,, the newer C 63 also has engine exhaust parts that are different, like the port shapes, and manifold
and cats thought so that is why it also sounds so different..

but the above will help get you in the right direction at least

mprsev

^^^ Thanks Storm!

Yes, I agree, I am trying to compare apples to oranges just because the three cars have the same motor. I just wish the E63 didn't get shafted on some of the nice things the other lines received, including the W204 which arguably is supposed to be the cheaper line.

I know I can go aftermarket exhaust, but for the price and simply sound I don't think it is worth it for me.

You bring up an interesting option of possibly swapping the C63 mufflers for mine and maybe removing one of the cats (I already removed resonator with x-pipe).

I wonder if there are any C63 owners selling their factory exhaust???

storm

well to clarify,,
I didnt say to remove the cats or resonator , dont like the sound of mercs when you do that,, louder does not equal better sound..

you should keep you cats, or put high flow 200 cell cats on the secondary
and keep stock primary..


so you can order the C63 mufflers, which are less exp I believe than the
new E 63.. and are smaller,,and LOUDER too

or you can go aftermarket.. for example the remus mufflers sound great,,
and their Universal smaller ovals will fit mercs, and are alot less expensive say only like 250 ea

Remus owns Sebring which makes AMG mufflers anyway,, lol
they are louder than the AMG, and sound better, not a burbly and have better midtone,, and are smoother,

if you want to go louder still, the renntech, or brabus are much louder,
but you could also get some fierce drone, as they put minimal sound deadening in them, and you dont have a RESONATOR.. which I recommend
just use a smaller type, like the BUllet, tube styles.
make sure the resonator is After the x-pipe and before the mufflers midway.. makes a great sound

Fr33kn63

No. I dont have any codes being thrown. Car runs and sounds great.

I had Hi-Flo Custom exhaust in Manassas did the work. Scott the owner hooked me up and did a great job. I know I have posted these links in the past but here are some pics.

These pics are old. But do show what I am referring to. I also have some sound clips, but will have to make some new ones. After my recent tuning the exhaust sounds a little different then when i made the originals. Would rather people hear what it sounds like now. I will get out tomorrow and take a new video.

One last thing. To prevent droning I installed Dynamat sound proofing along the entire exhaust on the heat shielding to prevent droning and excessive exhaust sound inside the car. And it works. Car sounds great outside, but nice and quiet inside, til I open the windows
