4inch systems for 600hp engine? for fresh water

Kurt Hamilton

I was going to use dana flow torque manifolds for my 540 build. I asked the question on here a while ago regarding what's best and I was told NA up to 800hp (I think?) there is no real difference between manifolds and tubed headers. I guess as long as your choice is rated for the hp your running they would all be similar?
I chose dana cause I like the look and I've always been happy with there service and finish.

stelling's are the best,,made more power then their headers,,then second to those are the keith eckerts header style manifolds..
