Mine is definitely the trend of doing “catless downpipes” and “resonator deletes” making your exhaust super raspy as a means of gaining more volume rather than doing a proper exhaust setup. Especially since high flow cats these days will flow more hp than most are making.
Stance, underglow, anything fake, and most importantly: anime decals
I don’t know what it’s called, but I see all these cars (mostly Toyota Camry/Corolla, Altimas, civics, etc) with this weird plastic bumps in a row on the roof along the top of the rear windshield. Usually coupled with a super dark tint and maybe a fake wing. So ugly and serves no apparent purpose.
vortex generators they serve a purpose if you have a wing lined up behind them and can actually go fast
useless on street though
