Judging by pictures, it looks as though it would fit. However, I don't trust my judgement enough to plunk down the money only to find out they don't work.

Any other tried and true avenues for headers on an '06 C230?

i doubt it'll fit...

it appears as though there would be room- judging by pictures. my main concern is the ports on the heads. i'm not familiar with MB. in the Chevy world i come from- all small blocks have the same port spacing. does MB do that on all of their 6 cylinders?

i don't think i care if it mates up with the cats- because those might get swapped to.
