Was wondering if anyone knows whether the m156 long tube headers for a W204 C63 would fit on a w164 ML63? I figure they have the same engine, same trans (I think?) so the heat shielding/transmission tunnel space must be similar...I can't find any affordable long tube header options for the ML63 but there are plenty of alternatives for the C63. Thoughts?

Wondering the same... anyone ever get an answer here. I guess I'll try to get it on a lift and measure. I only wonder if the exhaust needs to go "down further" in the ML than it would any of the others. Idk, i'm sure you could customize it. Anyone tried?

I've asked this question a few times and it's been a lot of no no no. It seems the Weistec are the only option but you would have to take delivery of these outside of the US if you are state side.

Seems to me a lot of the "no no no" people don't really know. Not saying that isn't true, but people are awful fast to nay-say something, especially if they vendor, or have already had that work done (or paid to have it done). My 2c.

Looks like SuperSprint makes headers to fit. Not cheap though…

I am currently looking for headers for my R63, which shares a sub-frame with the ML63.
A C63 setup will not fit on the ML as it does not fit on the R63.

I thought R's shared frames with R230/03-07 SL 🤔
I too am seeking LTs for my 2009 m156 powered w164 ML63 AMG!
