Hi there,
Old topic but I wonder if there is any documented performance gain out of these headers? Looks pretty much the same with stock manifolds except the material.
Thank you,

yes they are similar design but larger tubes. they made an extra 12hp on a 09 clk550
Thanks mate! Any chance to take a look at dyno graph? Is tune required?
Thank you again!
Thank you again!

I'd have to look. But doubt it. It was my personal vehicle about 3 or 4 years ago.
Anyone that got them says they notice a difference. Of course they aren't as good as long tubes. But there isnt many options on this engine. For the price they are worth it on a Mercedes.
No a tune isn't required. I had the clk tuned before we did headers and didn't change the tune.

Yes I agree that shorty is an easy bolt-on, I've heard long tubes gives some headache with O2 sensors issues causing check-engine light on.
And I got the EC tune on my vehicle, so it's a good news re-tune is not required, I can spare some $ for headers installation. I am still hoping I can try DIY but need to find some details on how to do it.
Thanks again buddy!

Has anyone heard back from old mate? Or know where to source any headers from? Long or short, apart from the obvious rentech and vrp?
Cheers guys

OPs account is based in Texas. Here: https://www.instagram.com/cdm_motorsports/ is a link to an CDM Motorsports Instagram page with a location listed as DFW area. The linked web domain is expired. Seems to me that this company isn’t active anymore.
