If you're in the same boat as most average people who didn't win the lottery or have rich daddy buy their car; spending 30k on a car is a serious chunk of change. I'm assuming you'd like that warranty which protects any issues of your recent 30k investment, to be intact.
Adding an access port or downpipe or both, is the fastest way to absolutely void that 5 year 60,000 cover your ass(CYA) warranty that was included with your new WRX on the most expensive parts of your vehicle(engine/transmission). The easiest way to protect that warranty is to add the SPT performance parts, or purchase parts that are easy to replace quickly AND without signs of being tampered with. I got about 600 miles on my WRB WRX hatch and the only mod I'm doing is an axle back because the SPT exhaust just doesn't deliver the note of the song I want my outback choir to sing from my Subaru. I can remove the axle back, spray paint a silver coating on the original bolts to show no signs of wear, and reinstall the stock muffler in less than half an hour.
Yeah, I got this figured out.
I love the scare tactics and misinformation.
Fact: Neither an accessport nor a downpipe will void your warranty. They can't legally void your warranty, but they CAN deny a claim. It doesn't mean that should, say, your AC compressor fail they won't fix it due to the presence of an accessport. Does it complicate potential warranty claims? Yes. Does it effectively kill your warranty? No.
You have to weigh out what matters most to you. Also consider how long you will keep your car. My intentions from day one were to keep the car long past the warranty period. Therefore, it was more important for me to run a safer map that lacked the known lean spots in the OEM map. The risk was worth the benefit. The power increase is a very nice bonus.
If you're looking for driver enjoyment, go with the suspension upgrades you mentioned and a short shifter, such as Kartboy. There's a lot of things you can do to make the car more enjoyable while still maintaining your warranty. Lastly, in the vast world of misinformation, a cat-back exhaust WILL NOT VOID YOUR WARRANTY. PERIOD. Do some research. Different exhausts sound very different on hatch vs sedan. The Q300 adds notoriously drone in the hatch.
