Accurate primary pipe diameter (1.500"?, 1.625"?, another size?)
Accurate collector pipe diameter (2.25"?, 2.50"?, another size?)
Since metric pipe is available in other sizes if your measurements are not exactly as above please state what you measured.
I would appreciate a PM on this.
At this point I would recommend these headers as the best available for the SC400 but have not had a set to actually examine and knowing the specific sizes will help me. Thank you.
I don't think they're available anymore, this is a long thread, and about the install, I read long ago you have to lower the tranny to make it easier, or pull the engine, not entirely out, to have some room, just my 2 cents.
