Correct. Throughout the model years, the C55, SLK55 and CLK55 engines are all the normally aspirated versions of the engines found in the E55, CL55, CLS55, SL55, etc.

they did it to handicap us! *shakes fist*

Bro you're killin me but I'll tell you again.

If you delete your secondary cats you will throw a CEL. You will be freeing up some power by replacing the stck 400cell secondary cats with some higher flowing Stainless Steel 200cell cats.

PS I will be replacing my stck muffler though with this:

in all black or this in stainless steel:

to reduce the weight that the stck AMG muffler leaves me with.

The W208 is a classic body style that will last forever. I only hope the W209 can come close to that. But it will never look better than the W208. I've had both body styles so I know.
Don't get me wrong. I still love my W209.

I love my 208!!! The aggressive body lines and the stout squared up trunk does it for me. I also like the newer bodied 209s. Its a toss up both great looking cars with amazing power!!!! Quick question though. Isn't the stock exhaust system diameter 2.5"? Where would I be able to find some 200 cell high flow cats? Does any one recommend stepping up to a 3" system from the the "Y" back vs. the stock system.

I just replaced my resonator and secondary cats on my W208 CLK55 with a Y pipe and have yet to throw a CEL... I only have about 30 miles on the new setup though.

Where did you get the y-pipe?

krispyw208- after the resonator it is 3" piping back to the muffler

Carl- My muffler is an eisenmann race muffler which is supposed to be lighter than the AMG.

I was told that the factory size on an 02 clk 55 was 2.5" not 3".

It is dual 2.5" up until the resonator, then its 3" back to the muffler

ok thanks. What about replacing the secondary cats with high flow's or put in the Y pipe..

I went down to our local performance shop here in Lubbock Texas and had them weld up a dual 2.5" inlet to 3" outlet y-pipe. Cost $100 and took about 45 min.

You can also use 180 deg mandrel bends to weld up x and y pipes like this:



I have purchased bends and pipe from these guys before: http://www.magnumforce.com/ubend.asp

Before adding more power, I'd prefer to have the K2 V.2 and Quaife ATB installed....

Spend some time on a wet track and you'll see my point.

What if you already have KW v.2, Kleemann LSD, and Brembo GT front BBK?

....the obvious choice....a CL65!

I'm just getting as much seat time as possible, so as improvements are made each step allows me to excel as a driver. Frankly, my remedial skills have yet to master the stock power on tap and I'm working on car control (on street tires) before I move to significant performance improvements.

whats a K2 V.2?

i agree, getting an LSD is very important. but i'm willing to bet that is a SC and an LSD cost the same, u would get the SC. just a hunch

Its KW v.2, KW is a company that makes suspensions and the V.2 allows for rid eheight and rebound adjustability

Coilovers

.....or just ask mbenzman to take me for a spin once in a while. $4/gal gas isn't going to make me jealous of a blower.






















Not really....I take that back!

They arent true coilovers for our W208's though

The W208 uses a separate spring/shock setup instead of a McPherson strut. The "coilovers" for the W208 are really just a matched shock and spring.

ok, thanks.

btw you have a really nice car collection

It's actually about 2.75 inches stck after the reso.

Don't worry it will!
Yes I did it. You'll fall in love with your car all over again. You'll notice.
