In my humble opinion, a LOUD exhaust will get more notice than lights. People react to noise a bit more than lighting.
Yes, it will get you noticed, and yes, they will react. Too bad it's not more positive.
For those that belong in the "loud pipes save lives" camp, I have a couple of scenarios to shoot that down.
1. A friend of mine rides a Harley with rather loud pipes. He is also a paramedic with the City Fire Department. I asked him if anybody ever pulled out in front of the ambulance. His response?
"Oh, yeah, all the time."
"You mean that even with all your flashing lights
and your siren and air horns, they still don't see you and pull out anyway?"
"Oh, yeah."
"And you expect your loud pipes that are pointing
backward to help you out?"
"Oh."
2. I was driving in downtown Dayton and heard the rumble of straight pipes, so I was looking around for the bike. (See, it
does work, sort of.) I kept hearing a bike but could not find it, so I started to ignore it. I finally found the bike. It was one block over, travelling the same direction I was, and the sound was bouncing around, echoing off all the tall buildings. I must admit that while looking all around to find the source of the noise, I could have easily missed something that I
should have seen directly in my path.
Since I ride a Gold Wing, it is probably obvious that I belong in the "quieter is better" camp. However, I do believe in the responsible and curteous use of headlight and brake light modulators along with all the other lights.
Go for the lights. Put on as many as you want, but also install a switch so they can be turned off if an officer is of the opinion that they should not be on.
If you put LEDs behind colored lenses, only use the same color LED. LEDs put out a rather narrow spectrum of light, so another color lens will just about block all the output of the LED.
