Hi folks

New here and only just starting to play with cars again
(15 years since I rebuilt one and a lots changed since then)

1999 Impreza sport 2.0 and planning to fit high flow filter and Magnex 6 inch x 4 inch oval exhaust system to start with on the engine.

Now bear with me, in the old days changing things like the above I needed to change the carb jets to get the correct mix again.
With the fuel injection on the impreza do any changes or is a retune need to be made to get back to the right mix??.

Lots of ther work planned but exahust is knackard and want to do intake kit for the hell of it.

Thanks Gary
