Why do you guys care WTF other people drive?
The article in question was straight trash.
With respect to caring WTF other people drive, I fckng hate straight piped cars that don't warrant it. If your car is rear/all wheel drive, has a manual or a serious double-clutch, okay. Otherwise, your car is an SUV or an economy car and all cat delete does is make stink and noise pollution. You got .2 more horsepower to the wheels, and 2000000% more donkeypower The overwhelming majority of passenger cars, anything header/exhaust, all it does is amplify a shitty engine note.
Trucks, especially lifted trucks, whose owners fucking insist on driving everywhere with their brights on. Busy suburban sprawl 20 miles from the nearest road without street lights galore. Brights. Well-traveled interstate, half a dozen cars within 80 yards of front bumper. Brights.
