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.

Thank you very much!
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!

OP hasn’t posted since 2017 so it would seem not.
