CLK 430
Need your expertise!!!!
Guys
Just had a rattling start in my car CLK430 a couple of weeks ago...YEAH the damn catalytic converter. The STEALERSHIP quoted me $2900 for the fix without labor!!!! These ah's should be given a beating...
Anyways...I checked alot of the old threads but I still have some questions to determine whsat course to follow so here goes:
1. What exhaust system would you recommend?
2. Does this system include catalytic converters and resonator?
3. Can I just eliminate the the cat converter and put a straight pipe? What if I eliminate 2 converters instead of all 4?
4. Should I replace the cat converter with a high flow aftermarket? How many would I need 1 or 4?
5. What is the diameter of the piping in a stock CLK430? Should I increase the size 1/4-1/2"?
6. Where can I get OEM parts for mercedes at a good price since OEMPARTSDIRECT seems to not be available?
7. Any other recommendation is welcome
Please share experiences and knowledge to help out a fellow CLK owner.
my car has 82K miles so i just missed the warranty coverage

Magnaflow’s 599xx series metal substrate converters sell for $115. They flow a lot better than the factory ceramic cats. The cats should be replaced in pairs. Either both primaries, or both secondaries. I would NOT increase the tubing size at the cat. The four cats on your car are made up of two OEM parts. The right side pipe has a list price of about $1400 and the left lists for $650. Trademotion will sell you the OEM parts for about 20% off list. Just be glad you don’t have a CLK320. The right side pipe on a 320 lists for $2500, and the left lists for $800.

I have the exact same problem and I am going to get the new cats from Evosport . com. They are only 275 for each side and higher flowing!! I am going to do a new exhaust and remove the resonator at the same time. So its gonna take me a bit longer to save up for the little project.

Anyways...I checked alot of the old threads but I still have some questions to determine whsat course to follow so here goes:
1. What exhaust system would you recommend? My first pick would be the one I just sold Eisenman Race!! Next choice would be a custom magnaflow
2. Does this system include catalytic converters and resonator? No cats and resonator will never be included with the purchase of an exhaust unless you buy it specifically made like that.
3. Can I just eliminate the the cat converter and put a straight pipe? What if I eliminate 2 converters instead of all 4?You can elimiate it of course BUT...you will probabyly fail your emissions test and almost certainly fail your visual emissions test when they get underneath to check.
4. Should I replace the cat converter with a high flow aftermarket? YES How many would I need 1 or 4? If replacing with a higher flowing one then replace all 4
5. What is the diameter of the piping in a stock CLK430? Should I increase the size 1/4-1/2"? ?? Someone please help me out here
6. Where can I get OEM parts for mercedes at a good price since OEMPARTSDIRECT seems to not be available? I need this info as well
7. Any other recommendation is welcome

CLK 430
Gregory...thanks for also sharing the info! I actually went to shop and they had available the magnaflow so I just had them installed and left the other pair stock (those with the O2 sensor). Cars sound exactly like stock and no real difference felt. I am considering taking off the resonator and changing the other two cats in the future. At least it should sound better...

How much did it cost to replace the cats with Magnaflow?
