I am a car person. I have a fun-to-drive car that I have modified. This guy is getting all the hate he deserves.
You don't get to be an assh*le and subject everyone to loud exhaust (I looked up his exhaust, it's 105 dB!), and be upset if people call you an assh*le.
Anyone who defends him is essentially saying "it's ok to be an assh*le to everyone around you, as long as you get yours."
