Anyone have a JMF v1?

Do I need to run this with an exhaust manifold?

What noticeable difference did you notice from this?

Can I run this with a stock Ko4 until I purchase a cst4?

I have no plans for meth or extra fuel. But not sure if I will change my mind down the road.
 
No you don't need to run it with and exhaust manifold but you'd get the most gains with one paired with it. Yes you can run it with k04
