Thread: extractors for a 2.6lt six

They did exist and were rare in their day let alone today.
I cant remember who made them but they were a 2 piece arrangement that in theory should of slowed down valve burning.
I havent driven a 6 for years but mine use to cruise at 105km/h without an overdrive so maybe they did have some effect.

Phil. Irving always opined that extractors on a road going low to medium tuned in-line six cylinder were a waste of money. His oft stated preference was for two independent systems of decent size all the way out. Usual firing order is 1-5-3-6-2-4 so you have 1-2-3 linked into one system and 4-5-6 into the other. I don't recall what a Rover six ex. manifold looks like so can't comment on the ease or difficulty of doing this. If difficult, you would probably get the best compromise with a big bore system of say 2 1/4"- 2 1/2" from the manifold outlets to the mufflers and a 3" or 2 x 2" from the mufflers out.
