Does anyone know how many horsepower the HKS single exhaust manifold with the to4 flange is capable of supporting before the exhaust starts to stack up and you need to go with an exhaust header manifold in ultra high horsepower applications? Thanks!

This is kind of a hard question. I guess it depends on your HP goals. If you are looking for more power than what a Garrett GT45 or PTE88 gives out, than you are going to have to go with a manifold that uses a T-6 Flange like how I'm gonna go

FULL-RACE.COM offers two styels of t6 manifolds , we use theses manifolds on our race cars and street cars.
