The numbers that Map's long runner exhaust manifold are throwing out are awesome. Yet, I'm also looking at Shearer's proven results and wondering which manifold I should get. If anyone has either Shearer's manifold or Map's Long Runner please let me know what number's you've imporved/experienced. And how the drive/spool feels.

 

I don't have neither of those, but I can tell you that moving to a tubular manifold, the tone will change and I did notice a bit of lag.

 

Our manifold is very new sir, as such there won't be much in the way of results besides what we have posted. I'm certain you would be very happy with our product should you decide to go that route though
