Default Want to upgrade, need suggestions

I have a 2019 wrx m6 and want to increase its performance but don't have much experience in this field. I am looking to do a full exhaust, intake, and tune .. am I on the right path? estimate costs? This is my daily driver so I don't want to go overboard and want to keep the motor safe.

Right path or not depends on power goals, budget, etc.

Great starting point on recommended parts from Phatbotti tuning:

Also would recommend researching heavily in the engine platform NASIOC subforum:

I agree. Find a tuner, and discuss your goals with them.

There is tons of info the FA20DIT forum.

Also tons of info on this site:

https://phatbottituning.com/faq-u

My personal opinion:
-Stay away from intakes
-Exhaust systems sound so, so on this platform
-E30 tune or flex fuel kit is the easiest, cheapest way to make great power
-Get a e-tune/protune from a reputable tuner (Bren, Ron Watson)

Start slow, get the AP from MAP. They will include their tune free if you buy it from them. See how you like that and move on from there. If you have access to E85, then COBB flex fuel kit and a pro/etune.

Short answer get a Cobb access port from MAP comes with their free tune. Offers decent power increase. If you want more try their e30 tune. I waited almost a year before modding but I donít regret it. Itís your money and car so I would do tons of research before pulling the trigger on anything.

Thank you for the advice! I'm going to do more research with the flex fuel kit. I want to stay under 5k with the whole setup. Would I need to upgrade my fuel pump? Any other suggested parts to upgrade with the kit? Keeping my engine and other internals safe is my number one priority.

Thank you for your time and knowledge!

The FIRST you should do is ensure your car is running good before you start modifying it. Subaru engines are susceptible to knock and blow-by (if you don't know what these terms mean, learn what they mean and how they happen before mods). OEM ECU does not report knock unless it's a major event such as misfire.

Buy a cobb access port. It has many features to see how your car is running. Ensure your car doesn't have knock. Establish baseline data logs, and THEN start modding. If you start modding now, and you happen to have issues, those issues will only worsen with the mods. Also, you won't know if the mod is caused the issue or not.

It is the opposite.

Ericsson, the knock control system on your EJ is completely and fundamental different than it is for FAs
FAs catch all kinds of knock, often false knock, and is roughly 10x more reactive than an EJ.

To suggest that his ECU will only pick up huge events like misfires is completely false and shows a complete lack of education with regards to the new models. Stop giving out advice when you clearly dont know what you are talking about.
