Profab Castflow manifolds & upipes vs. Proflow

[2005LLY]

Proflow headers and up pipes or Castflow manifolds and up pipes... Whats the difference between the two? Which would I benefit more from? Truck will have 100% injectors, 2xcp3, 68mm cheetah.. I will twin over it once I build the motor with either a 4508 or a 4718 haven't decided yet..

Thanks Dylan

The cast flow manifolds will hold up to the heat better and you don’t sacrifice flow. :thumb:

Just because you race more doesn't mean you're not slow
