Rally-car wannabes
Aw, come on, admit it. You've seen 'em. You've snickered at 'em. Teenaged boys wearing baseball caps, wraparound shades, and maybe even racing gloves, proudly gunning the silly little 90 horsepower 4-cylinder lawnmower engines of their Honda Civics or 3-cylinder Suzukis. Typically, they'll take off from the stop light with a cacophony of noise, but they'll barely outrace the minivan in the next lane.
They have some of Daddy's money and they want to look cool but they can't afford a real sports car, so what do they do? They grab a little economy car, and they dress it up! Does it have gimpy wheels? No problem- run out and buy shiny alloy wheels, complete with such incredibly low profile tires that you almost can't see any rubber at all!
Does the body look plain? No problem- run out and buy ground-effects kits, and warp all of that useless shit around the bottom of your quarter panels and doors! Then, buy a spoiler for the trunk lid, and bolt it on as if you really need the extra downforce at 80 km/h (on the rear wheels of a front wheel drive car). You might even want to cut channels in your hood, for that authentic Ram Air look.
But for the coup de grace, they must commit the final atrocity. Yes, we all know what it is. It's the big fat exhaust pipe! They replace the exhaust system with a "high flow" system, so their little 90 horsepower engine will sound just like the throaty roar of a Dodge Viper's V-10! Of course, that's what they think. In reality, it just sounds like a lawnmower with a bad muffler, which is precisely what it is. In fact, it actually robs the engine of horsepower, because the engine's cylinder heads, intake manifold, valve timing, and fuel injection system were all designed for a certain amount of exhaust system back pressure (not that these dipshits would understand this).
If you drive one of these ridiculous little rally-car wannabes, take it from me: the ersatz rally-car look doesn't fool anyone. You don't look like Mario Andretti; you just look like a dork with a serious psychological inadequacy problem.
