Frequently asked questions
What is stage 1 and stage 2?
Stage 1 means there are not modifications to your car at all. A stage 1 tune can still provide more power and better response over the stock tune so it can still be very much worth doing. On newer Subarus, it will eliminate a dangerous lean condition that exists often when going into boost.
Stage 2 means you are adding replacing the factory downpipe with an aftermarket one. These come in two main varieties, catted and catless. Catless is more free flowing, catted has a small, high flow catalytic converter. It can have less raw exahust smell and be a little quieter but can cost more as well.
