The stock bazooka muffler is so quiet I can't hear the engine at all. Is there a way to take out some of the silencing materials or baffles w/o changing the tune or re-flashing the ECU? I just need a little more engine symphony if ya know what I mean...

There are some who have modified the stock muffler with varying degrees of success. You should be able to use an aftermarket slipon without needing fueling modification if that's all you do.

+1, add aftermarket slipon.

Some guys have shortened the stock can for a lil more gusto. It's still butt ugly IMO.

Get you an Area P slip on, no engine tuning required. At idle it's a bit louder than stock. At cruising speed it's about the same. When you get on it, it sings a VERY sweet song.

The area p stainless slip on seems reasonable priced and comparable to stock. Yet better looking.
Is this" lean" comment on their site anything to be concerned with ? -

 Slip-On - Power increase starts immediately from 2500 rpm and carries through peak at 9250 rpm. Very linear. Increase was 5.62 horsepower and 4.68 foot pound torque. The chart shows runs with the 18" muffler/2.0" core. The stock fuel curve was slightly lean in spots up to about 8000 rpm, then rich on top end.  Although not required, It may benefit with the addition of a PC3/V.
 
Especially if a more efficent air filter also added ?

I bought my Area P slightly used on this site for $285.  It looks
and sounds great.....not loud at all unless your really reving it. 
I have about 20k on it with no PC and OEM air filter.

Passing through lean spots in the rpm range is not going to hurt. Extended use in a lean condition will of course damage an engine but other than flat road cruising you are seldom flat lined at a given rpm.  Air filter discussions are kind of like oil or tire threads, lots of data interpreted many different ways. The stock air filter presumably flows very well and there is no immediate reason to change. I like the ability to clean and reuse the K&N and BMC filters rather than have to replace.

Maybe you have damaged your hearing with loud exhausts? 
I can hear mine just fine.  Sounds like a bike should be, to me....  smooth and non-annoying.   Yes, I know that is not for everyone.

Mine runs better than ever with my Area P, no lean spots at all. And it actually emits a nice pleasant tone unlike Maxtog's ride.

It's also possible that the OP hasn't figured out how to start the engine because of KiPass.  LOL

I prefer quieter exhausts, and am happy with the stock muffler.  It is very easy to hear, especially at WOT.  I used to think that "loud pipes save lives" was a Harley/cruiser thing, but experience has proven that lots of people seem to hold to the doctrine, even if they don't preach it in those words.

Loud pipes get old real fast, and I'm old enough already.

Whether one likes a loud pipe or not is a personal preference. Some like them loud, others do not. I personally like to hear the full sound of the engine, like a deep growl, which means an after-market muffler. This issue has been debated fully on this site, and there is no consensus regarding sound nor a specific after-market muffler. My suggestion is that you do a search of  "Battle of the Cans." Then, decide what is best for you.

Thanks for sharing your opinion about the "loud pipes save lives" issue Clyde. I can assure you that I do not subscribe to that doctrine. That's what I like about the Area P. If I ride and keep my wrist in check, the Area P is about the same as the ugly stocker, sound wise. But sometimes I just want to let her rip and when I do, I want to hear Connie sing. I never do this in traffic FYI.

I really like my Area P slip-on, I find I can turn some heads if I want to.

Depends on the kind of riding your doing. If your out for a short day ride a LITTLE rumble might be fine, If your on a vacation and on the bike for several hours over several days I like quiet. I listen to music and have a CB to communicate with other bikes, loud pipes, after a while get annoying, at least to me.

As I said, the Area P is about the same as the stocker duing normal 'crusing' or on the highway. It's when you get on it that you hear the difference. See the numbers below from Area P's site.

           Idle            5000rpm
 
Stock   77-78 dbA    92-93 dbA
 
Slip-On 83-84 dbA    92-93 dbA

I like quiet exhausts.  And I can hear my engine just fine when I rev it up over the entire RPM band.

I like moderately loud exhausts.  I love the look and sound of my CS One. 

The factory muffler is huge and U-G-L-Y.   

vance and hines CS 1 looks and sounds the best.

My Area P only sounds loud in the garage.  So I stopped riding in there.
