Get some loud exhaust.. lol - personally, that's how I notice people a lot of the time, is by sound... lol, but in my cobra ive had 3 races... M3, C5 LS1 Vette, and a M5... Only reason I even raced them was because I was bored, lol - knew i'd handle all of em, lol. Well the m3 because he had his pretty blonde girlfriend in the car 
Exhaust will let people know that you'll run.
but not racing, isn't a bad thing - most of the time i race myself, and i love feeling the torque 0-60, haha.
