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.
For Teslas, most of the mods look atrocious. It just makes it look super ricer. But I feel the worst is the aftermarket letters on the back that spell out T E S L A. Like we get it, you have one. Especially in California where everyone and their grandmother seems to have a Tesla now.
