I was looking at both. The c63 from 2008-2011 were going to feel like a downgrade interior wise majorly from the CLS 55. And the C rides pretty rough after being in the CLS for a year. So I started either looking at 2012 c63 or 2010 e63... or heavily modified 2008-2011 c63. Something about front LEDS too lol.
I found a few and looked for a bit. Honestly I was close to pulling trigger on c63 but this particular e63 was calling my name. It had a good history and low mileage and warranty. I'm glad at this point I went with e63 because you see much less of them modified and I like the pano roof and other more luxurious features... while still being able to lay down some nasty **** with that engine.
So I guess it was mainly availability in my search but I'm happy I went with the w212.
I can't wait to get more HP on this bad boy, fully stock now performance wise (except for res delete which is basically nothing). I haven't even put my ROW boxes on because I haven't seen a lot of dyno's comparing with NA, then ROW box, then I'll have tune. Assuming everything is healthy to start.
I probably will remove the secondary cats as well.
I've had Eurocharged tune on my 500 and 55 and its fantastic on both. If I didn't already have a tuner I would go with the Eurocharged v5 tune.
Having said that, ESS tuning is down the street and my friend owns/runs it. They are entering the market soon. I am going to go down there for a dyno tune. Similarly if I was going to gput on supercharger I would go with ESS over Weistec. I will most likely keep this car NA though.
My tuner is busy tuning 800+ hp Beamers this week and last, so I went ahead and tossed on my ROW Airbox. You can buy these from various places. A nice trick is the 2007 clk63 black series is the only US car with ROW airboxes, so you can buy those the cheapest probably.
So I wasn't able to dyno before and after the ROW but oh well. The car does burble and pop slightly more than before, and perhaps is a little louder. The real benefit of the airbox will be seen when I go get car tuned.
Are you going to get the car decatted and then do the tune? That's the best bet for the highest gains and to get the most from your tune.
Ideally...if your friend can give you a precise dyno tune rather than a box tune, you'll see eve better gains with the tune and decat.
Keep us posted and please do a before/after if you're feeling generous
No I'm probably not going to de-cat before I go get some tuning done, but maybe at same time. They have an x-pipe that can start behind the cats, or delete the cats, or go with high-flow cats, so I will decide then. I think at minimum I'm going to try to dyno as is (just res delete) and then again with Xpipe and Tune. It's pretty up in the air at the moment.
Long tubes into xpipe with res delete is the long term plan, with either hfc or no cats. Starting with xpipe and tune though most likely.

Keep us posted man. I think the average gain without touching the exhaust is around 15hp peak and a slight increase in torque under the curve. I guess there's only so much that an increase in ignition timing can do, without having additional airflow to play with.
I finally installed some extra knock for my stereo system by installing the kicker box and amp in the trunk as seen below. This was taken out of my CLS. There is also a bass knob by the center console. This really compliments the stock HK system very well, as it did on my previous car. The amp is drilled down next to the spare, and the box itself can be moved easily. Sounds great
Love the wheels. How does your car ride with the springs and links?
It rides really nicely when you are on comfort suspension. On AMG-2 it is a little rough as expected.
I can't really compare because I don't have a lot of experience driving a stock E class setup. I will say that it rides less comfortably then my CLS-55, but more comfortably then my CLK500. Overall it rides amazing! Never had a complaint about the ride comfort... unless I'm on sport 2 and the road gets bumpy.
But I do live in Phoenix and (most of) the roads are all perfectly flat and nice
Is there any drone from the straight pipes replacing the resonators compared to the stock setup? I'm planning on getting the full Weistec exhaust for my 2011, but want something cheap for right now to add a bit of sound on the throttle without losing the popping and grumbling, and without adding drone. Next will probably be the ROW airboxes and a tune.
You mentioned secondary cats btw - I'm 99.99% sure that the E63 only has one set of cats. I'm planning on doing the high-flows when I add the long tube headers.
I was with my friend when he got his secondary cats removed on his 2010. I don't think they're cats at all. They had no honeycomb material inside; I think that they're just bubble resonators. Oh yeah and just those delete alone provided very little increase in sound. He's going back for resonator delete in a couple weeks.
Well, I replaced the resonator and it made a huge difference. It was almost too loud at part throttle for my middle-aged sensibilities, but the worst part was that it sounded less like an AMG and more like a truck. I went back and added a smaller H-pipe (the resonator has one built in), and really like the result. Its basically stock sounding at idle and gentle throttle, but around 50% louder when I get into it while retaining that nice rasp.
If anyone needs a custom exhaust shop here in Austin, TX I can't say enough good things about the guys at Muffin Muffler btw.
Sorry I've been away and haven't been responding to the thread. I like how it sounds with just resonator delete, but it does have more of that "truck" sound as RJ said above. H-pipe should work great too, glad you like it!
Right now I got a new problem I'm dealing with. This past week on startup the car was making this strange rattle noise. At first I thought it was exhaust (kind of sounded like a cheap exhaust or something rattling) so I took it to my exhaust shop. Up on the lift we couldn't see anything wrong with exhaust. I did some searching and found a similar video of a guy with a 2010 e63 that was making the same strange noise... he discovered it was a loose cam shaft belt tensioner.
My main autohaus is looking at it now and they confirm it may be a belt tensioner, but really only the dealer has the tools to fix that. So let's see where this saga leads us
Still going to get together with my friend at ESS tuning whenever I am free, can't believe I've had this car so long without a tune! But man its so enjoyable.
