i have a pair of stock e55 headers in great shape off my 06 just sitting in my garage. make me an offer

 

wtf lmaooooooooooooooooooooooooooooooooooooooo

 

I know e55 won't fit c55 different flange angle. (Source: accidentally bought e55 manifold to put on my old c55) so I would say no, they won't.

 

You can get E55 manifolds in that "shorty" design but there is little benefit. The real restriction is the header to downpipe (cat converter) flange. Unless you eliminate that, you won't gain much. I would just stick with the stock ones if I were you, they are pretty reliable.

Unless you can somehow smog a mid length or long tube header with cats in there somehow....

 

I was thinking about doing this. Getting E55 headers for my C55. I would like to run a set of maximizers but they don't make them for the C55. So when you say flange angle do you mean that the tubes come off the flange at a different angle? I know that sounds stupid but I'm just trying to do my due diligence and research before I buy some 2500k parts.

Those will not fit. You can find shorty header for the 300 range used. Facebook has the most action. Shorty will get you 20hp mids 30hp longtubes 40. This is so consistent if you do the research on each.
