[Boostn]

Hi All,

Did a search couldn't find an answer.

What is the Power limit of Stock FG exhaust Euro 3.

Have a look at the nizpro site - On the exhaust side of things, they go a fair way with power increases without any changes, then a bit further with just a cat change.

There is no definate answer because the exhaust becomes more of a restriction the higher amount of air you try push through it, the general consensus is after 300rwkw the FG exhaust should be upgraded so if your going a bigger turbo then you need an exhaust upgrade.

ute or sedan?

From my investigations for my own car they recommend changing the exhaust at around 320-330rwkw. Again, you could prob make more power than this without it but the back pressure on the turbine wheel becomes counter productive and pushes the turbo a bit too hard. Obviously when putting on a whole system, wastegates need porting to control boost due to the more free flowing nature of the larger exhaust.
