I never liked how 4s sounded, and especially hate the brats around here that run em with fart cannons. Ear splitting VRUHHHHH angry farting bumblebee hulk sewing machine jacked up on speed. Coincidentally I also hate the trucks without mufflers, I guess im not big on noisy street machines. On the track it's different... then again i guess its all about sound, you can -really- tell who's running crappy pipes just to make their ride sound more powerful, when it just sounds crappy and the guys with real power, sound decent and generally dont even need to run stuff like cherry-bombs or straights.
