Flat spot? What flat spot? (k-tec manifold)


Paid Member
So I got a K-tec exhaust manifold fitted yesterday (on an otherwise stock exhaust) and I was expecting a big fat flat spot somewhere in the rev range but I don't notice anything other than it being slightly louder on throttle. Where exactly is the flat spot supposed to be, between which revs? Is it really that noticeable as everyone seems to claim?

Normally between 2.5-3k. But I remember reading Ktec have put a lot of time into this 3rd gen manifold to rule out flat spots.
