Last week, I fit the famous Power-engineering exhaust manifold on my MY 98. It adds lots of power above 3000 rpm, the car is much easier to drive. The boxersound is lost, but replaced by a kind of WRC-sound.
It is amazing to feel how you are pushed back now in the driverseat! Never had tis sensation before!

 

Turboke,

Do you also have PE Phase 1 as well. What are your figures?

 

Do you miss the "Boxer" sound?

How much did they charge you for the manifold?
