So I'm about to drill the baffle on a dyna muffler. Which do you think would produce a deeper, less raspy tone: 3 or 4 smaller holes (11/32 or below) or one big one (3/4). Or would make any difference?

Yea I just hate to hear my bike fire up in the morning. The straight pipe brings me to the point of insanity. Hate myself, love myself, touch myself. It gets so confusing!

What makes people hate bikers is bikers. The way you act on the road. Polite, defensive riders usually have no negative results from their exhaust. If you're out there tearing up the roads like you are the only one there it wont matter what pipes you have. You're gonna give us all a bad name. Don't belive it? When is the last time you saw a GSX-R tearing down the road pissing people off? Was it the volume of the pipe you noticed? If volume of the pipe determined how the motorcyclist was perceived you could pull a wheelie on a stock Savage going down the interstate @ 80mph and nobody would even notice.

Loud pipes are not going to kill my wife or kids as they go to school. Some idiot trying to show how "good" he can ride as he passes in curves and rides wheelies on public roads on the other hand might. And I'm not picking on any one group in particular. I'm just making a point.

You want to set a positive example? Show some respect for the other guy. Cage, Bike, Semi,  no matter what they are driving they will think better of you/us as a whole from a simple act of kindness before they ever worry about how loud your bike is.

Drill the pipe if you want. It's your bike.  

My opinion, Don't leave anything but the chrome, and then paint that black!

I agree that it is your own bike and you can do whatever you want to make it your own.

However, I do have to say that very loud pipes do annoy people separately from the way some bikers drive. Although they are related.

In the warm weather, I keep the front door of my store open. Whenever a bike with a combination of very loud pipes and a driver who accelerates quickly away from the stop sign  goes by, I see the expressions of annoyance on my customers faces.

A pipe that is just as loud, with a slower acceleration doesn't draw the same reaction - primarily because the decibel level is lower.

3/4 inch hole in my baffle. Not annoyingly loud, but bike breathes better.

Ok, ok, ok. I do agree "obnoxiously" loud pipes, being filled with "wring the grip off" throttle are a pain in the @ss for all of us. And yes if you have to wear ear plugs to ride they are way too loud. But my point is still the same. The loud pipes are mostly overlooked as long as the rider is respectfull. If the bike is being ridden in a manner to bring the db level to it's max then it's the rider not being respectfull that's the problem. Not the pipes. Modest acceleration/deceleration and avoiding that annoying "blip" at the stoplights will keep even the loudest of pipes tamed. Loud when you want/need to be and tolerable when not, but always curteous.
