Thought this would be valuable to some people including myself.
Being that RHD cars don't have the steering column on the exhaust side, do any RHD headers clear the steering column on LHD AE86s?
If you have any info would you please share.
Thank you in advanced =)

here are a few I know off the top of my head.

one is Silk Road. they're high rise and equal length tubing.
I heard of an old HKS model that supposedly fits LHD. but you gotta be careful, as it is only a specific style from HKS that fits. otherwise, HKS is all RHD only
and I guess TRD. they shouldn't have a diff version in Japan compared to what was sold here in N.America

The TRD North America header was never sold in Japan, and is specific for the US market made by Doug Thorley headers.

The impulse header was designed to fit lhd.

Ditto on the Silk Road, but I believe it requires a manual rack to fit.
