I asked him "what do you mean by smells bad"? He said it smells really strong of gasoline.
He doesn't ride. So, I don't know what "really bad" is. Should the car following behind you smell any gasoline smell at all at parking lot speeds?

Sometimes exhaust can be odoriferous (big word there). Especially if you run a tad rich, but it's not a real problem. As the AFR leans out a bit it should go away. Gas formula, an incomplete combustion, improperly tuned carbs can all contribute to exhaust smell. Remember you basically have a straight exhaust with your slip on, no resonator, baffle or expansion chamber to change the flow of exhaust coming out of the engine. just an empty tin can between you and the engine.
Really bad is, if you can smell it. Next time put some
Cherry Bomb or Groovy Grape in the tank, then have him take a whiff. Watch the reactions of everyone else too.
Try some Iridium Spark Plugs and see you if get a better spark and more complete combustion. A more efficient spark can burn gas better and with help mpg.
