Hi,

which manifold would be the best choice in terms of overall performance for my (non rs1600i) cvh engine?
specs: 1600cc k-tronic, gas flowed head, K&N, Kent cvh32 cam.
Have an Ashley 4-2-1 but this looks to be quite small and thin (inner diameter primary tubes 34mm), would an original cast-iron RS1600i be the better choice?
