Straight pipes or not?

I want to start a discussion concerning straight pipes. Not necessarily on our bikes but on bikes in general.
I like a good deep rumble coming from mine, but I personally don't like straight open pipes.
People say loud pipes save lives. I'm sorry, but I don't buy it.
I hear a lot of bikes around here with straight pipes, and you can hear them from a long ways away, but only after they go by. When I'm going to Boise in my truck, I don't hear the bikes until they go past me, then I hear the pipes.
As the old saying goes, how are they going to save lives if you can't hear them until they are on top of you, or past you?
So please, I don't want any pissing matches, I just want to hear what you think on the matter.
The bike I just bought has the goats belly removed with Harley Dyna mufflers on each pipe. The pipes have catalysts in each one so they aren't too loud.
I'm thinking about removing the catalysts so they will be straight through.
You can't see through the pipes. Looks like there are tiny catalytic converters in each one. They come off of a newer Dyna with FI.
Questions, comments?

one down side to straight pipes (besides being super loud, unless you like that sort of thing) is that you lose a little hp due to the lack of back pressure.

on another note we could maybe point our pipes forward, then the cagers will here us comming! lol

I also like the deep rumble and to be able to hear my bike, but not so loud that I don't hear other bikes... I love to ride the mountain roads and being able to hear the bikes riding with me lets me know what they are doing, on the gas or off the gas, important to me especially if they are out of view in a sharp turn or behind trees or whatever ...
Just me, to each their own, it's your bike & ears...lol...
Have a good one...Old Dog...

Small rumble ain't bad. Loud pipes remind me of sitting at a traffic light and some kid with the boom boom stereo system sitting behind you and you can't hear your own radio. The straight pipes are just a pain in the ear to most everyone but the driver of the bike and that's cause he has on a helmet and is sitting in front of the racket to start with. Can't stand a load short pipe to start with. Sound like a engine on steroids trying to puke. And most people who use them don't realize the damage that they can do to an engine.

I said it once and I'll say it again....

Anyone running straight unmuffled pipes on a bike out on public roads is an assshole.
Just my opinion of course......

Straight pipes:

1. Hearing damage
2. Illegal
3. Not proven safer
4. Some people think, "cool", some people think, "what an ass."

I don't like straight pipes and don't think these bikes sound good with a loud exhaust in my opinion, especially on the highway since they rev high. You won't get a deep rumble at idle with straights- the cylinders aren't big enough, so you'll get loud gun shot popping. Some muffling actually creates a deeper tone and the goat's gut enhances that. Longer pipes do also. There's my 2 cents and some lint...
