Hey guys, not sure if I'm posting this in the correct spot but i thought you all might be of some help, i wanted to use some m52 exhaust manifolds on my m54 because apparently they do bolt up to the head just fine, but something else caught my eye, the ss autochrome e36 headers look like a little bit better design and arent too expensive, does anyone know if there is enough space between the bottom flange of the header and the side of the engine bay? Any help would be appreciated, if not then I'll just buy some oem m52 manifolds. Thanks
