Searching first is encouraged ;)

get an obnoxiously loud muffler and nothign else the other cars will be so scared to race because ur car will roar like a pissed off weed wacker and i mean comeon weed wackers are dangerous :O

turbo cars dont roar like weed eaters. lol even with no muffler my car never sounded like a weed eater. btw i dont think you know much about cars since your profile says you have a 1902 geo tracker lmfao

loler i was joking aha! I love dsms and btw dont diss my 1902 Geo Tracker its the shit

they didnt even make a 1902 tracker, did they? post a pic of it

Seems to me he probably missed the "9" on his keyboard ;)
