Hi everyone i currently own a 2010 dodge avenger and i was doing research for a good all wheel drive car and i stumbled upon the 2015 wrx. I'm only 18 years old and has been working since 15 with a great online job so i have money saved up and even possibly to pay for the car without financing. I remember My older brother has always told me he wanted one and as i looked more and more into the car i really want it now. I have some questions though for if i plan on future upgrades. My brother told me that if i upgrade more than the intake like an exhaust system it is better that i'd do a tune like an access port to be safe and to utilize its full potential. I'm wondering if this is safe but he's telling me a stage 1 is fine for minor upgrades.
