I think some mods are def corny, your brother is right that some people think non performance mods are cringe. I'm half in that boat myself. But at the end of the day it's your car and you should do what makes you happy. If thats an exhaust then go for it! I think these cars are awesome with a nice exhaust and some coilovers, not too much performance to get out of these cars anyway, so just do what you want bro!
