Im thinking about removing my resonator on my exhaust on my 04 clk55, Just wanted to get some opinions from anyone who has done this, or if its a good mod?? Thanks.

Good idea and remove the secondary cats too. Will give you a more throaty sound without being too invasive

W209 CLK55 doesn't have resonator anymore. Think about removing secondary cats, that will give you some more growl.

elijah

It's one of the cheapest and most appreciated modifications on this forum. For a few bucks you get a mean menacing growl!! Well worth it IMO

Hell ya !

do it

I'm very happy with mine

Did you notice any loss in power??

DRBC43AMG

Why do you think you will get a loss of power? Most likely get a slight increase of power with the faster and better exhaust flow.

Someone I know told me you lose top end due to less back pressure...But it sounded kinda off to me.

dr_npz

Nope, you can loose some low end torque due to less backpressure, but if you do it right, you shouldn't loose anything. Besides that, you will certainly gain some top end hp and torque, due to better flow.

I am very happy with my quad exhaust (2nd cat and muffler delete, now using one magnaflow 14" resonated x-pipe in the place of 2nd cats) - sounds really mean !!! It is loud, but still drivable. This is what it needed.

elijah

I know for a fact that BMW E60 owners doing the quad setup to resemble the M5 lose a significant amou t of top end and this happens to all of them but our Benz were built for this.
As mentioned previously if you do it right there shouldnt be any losses.

FatTony001

Nope ! No loss in power

has someone got a video of the secondary cats being deleted, would like to know what it sounds like but i do it, or maybe i should just go cat back exhaust.

I had it done on 04 CLK55 for about $350.00. IMO it was a waste of money and I did not notice any performance gains.

clk55dom

did you notice any sound difference or do you really have to change the muffler to notice that change.

LOVEMYBS

I didn't notice any sound difference.

Will deleting secondary cats affect smog??

MarcusF

If they do a visual and they know what they're looking at, you will fail. It's common for some California Test Only Centers to roll the mirror on wheels under the car for a 'look see'. When I interview a smog station, I watch how they test the cars before me. If I see a mirror, I walk.

hami

do u have any pictures of how the setup looks like?
i was thinking of deleting the secondaries but I already have eisenmann mufflers and the car is loud enough. all I want to do is get better flow and eliminate any restrictions

togaclk55

I got mine done last week for $140, the car sounds so mean now.

clk63DK

Anyone that has done this on a 6.3AMG?

What pipe do you replace the muffler with?

cjclk55amg

will I have any trouble passing emissions if I do this mod?

DRBC43AMG

NO problems

Here is what it sounds like on my C43: http://www.youtube.com/watch?v=j6XrJmITtmg

howie

I did the res delete only and gained some sound and top end...not sure if I lost any bottom end tqe, if so, very minimal.
