My wife has a 2018 WRX base. When we bought the car, I had them put on a STI exhaust. She was going to trade it in for a 2021 WRX Sti when there were rumors that it would have 350hp. Well that didn't happen and I really didn't want to keep buying a new car every few years. I talked her into modifying this car. She's never done anything like this, but she is doing little things to get started. She's done most of the superficial things, but now i want to start her working on getting the HP up. She was concerned about taking the car apart, but fortunately my son has a 2003 outback and the clutch went out. I replaced the clutch in his car, so now she fells a little better.
All this is to get to the question; What mods can she do to increase HP without voiding the warranty? After the warranty, we will install the cobbs programmer and anything we can to get to 350. I read that 350 is as far as we can go safely.
