K Series Exhaust Manifold.

A work of art from Jim. I asked for 1 and 3/4 inch all the way to the manifold for my ported VHPD head and Jim agreed it was the best idea. Also a flexy SCRP to help with the noise hopefully.

Thank you Martin!

 

Any K-series manifold you see with a flexy is a compromised design - i.e. the secondary lengths are wrong. The 2bular K-series 4-2-1 comes with its own flexy de-cat pipe (you do need a flexy somewhere in the system) included in the price. This pipe is 57mm diameter - the correct bore for best power/torque (not the 63.5mm dia supplied by numpties).

If you spec a Cat, I weld the flexy in before it. If you have your own Cat, send it to me and I'll weld in a flexy section.

Great looking piece of engineering.

 

What sort of price would one of these set you back?
