I would like to get a high performance exhaust, however I do not want it to be extremely loud. I currently have SEII pipes and do not want anything louder.

Is there any such thing?

the HD touring mufflers come on the SE 103 bikes, and they are 80db EPA compliant, pretty quiet.

i had 2 sets, and both were too quiet for me.

I have the SE 16 Gauge Double Barrel on my 05 WG and think they make very good power, excellent lowend torque and are louder than stock but not as loud as V&H BSS, which they look very similar to (V&H makes them for HD).

Most guys don't like the 16 Gauge, say too quiet. :coffee:

No,
HIGH performance and QUIET do not exist.
MEDIUM performance and QUIET does exist.
ANYTHING that you put in the exhaust tract decreases flow, thus decreases power.

At this time there is no real good muffler core design that flows enough to produce the power of an "open core" design............but I am working on it !!!

I am riding an 04 Heritage Softail.

OK, this will sound really crazy, what if I were to put a muffler from a CAGE into one of my bags and then run my current exhaust though this?

Would that allow the flow that I need and quite the bike down and keep the perfomrance?

Or am I talking out the side of my neck. :(

No, I don't think this exists in terms we know now. I have seen some prototypes of future "green cars" that use engines and electric motors, and some sports cars and trucks are being built.

Whenever mankind developes a new invention, he first uses the new technology for war and sex. Splitting the atom first brought us the A-bomb, and the internet is dominated by pornography. Any "green power" will be used for these purposes first.

When you first see an eco-friendly assault rifle and a quiet vibrator, then silent power is waiting in the wings.

I have a 03 Heritage and went with the torque slip on mufflers. not as free flowing as the others out there but louder than stock and more power than stock. not obnoxious to me either.

good luck and ride safe.

oh and putting a muffler in your bags, that's thinking ouside of the box. I guess many inventors have been called crazy at first. sounds crazy to me.

ACTUALLY, you are in the ballpark, in order to MAKE POWER you need to increase flow, LARGER chambers in mufflers are needed.
Look at modern sportbikes, they have moved from the ugly LARGE mufflers to under frame BIG suitcase mufflers, more chambers to dampen sound= better flow= more power.

Supertrap 2 into 1 are pretty quiet (a little more rumble than stock pipes, but way quieter than your SE slip-ons), and post decent numbers. Do a search on the forum.

S&S has what they call their "SPO" mufflers. From what I've read, the people that do have them around here like them. Although they are a large muffler, they apparently provide quiet without sacrificing performance.

Do a search.

I have an 03 Heritage and installed the White Brother's 2:1 pipes (W Bro's does not make them anymore). I got outstanding results for bottom end TQ and I like the sound. I have to idle thru parking lots to avoid setting off alarms but the noise usually does not kick in unless I crank on the throttle.

These are the tunable design pipes (discs). The SuperTrapps are very similar. They recommend using 20 discs with the closed end (provides the back pressure needed) but you can make it louder by putting on their open end and reduce the number of discs to achieve the same flow volume but with more sound. (your choice)

The Vance and Hines are not tuneable (at least no discs) and are much louder from what I have been told.

On my 03 FLSTFI 98" Woods6hg, etc, I had the Supertrpp dual crossovers. I gained 10hp lost no tq and they were very quiet! very good for the long trips!

Here at Flowmaster, we're beginning to experiment with bikes. We have built a couple of mufflers/systems for Buells (one a local race team), and hopefully sooner rather than later will start playing with 'real' Harleys. My NT has Cycle Shack slip-ons, which, according to our owner (Ray Flugger- inventor of Flows) work well, but are known to be pretty loud. I'd like to quiet mine, and would like a 2-1. Our R&D guys are working on our merge collectors and head pipes, and also muffler designs with HDs in mind.
Ray, by the way, has quite a history with HD (the company) going back many years. Keep your fingers crossed!

Interesting to see Team "F" in the hunt for motorcycle exhaust stardum.

""but are known to be pretty loud""

When I was at SuperTrapp the sales guys would often send me a car guy that had Team "F" on and wanted information on how "them thar" disc mufflers would work on their cage....."to quiet it down".

Small world..welcome fellow exhaust pulse wave damper !!

Check out this link.

http://www.rbracing-rsr.com/lsr21blackhole.htm

There are a couple of video files you can listen to. They make quality stuff.

I was just reading this site on the Black Holes, Do you know anyone that has a set and if so how do they like them and what is the noise level. Also, anyone got any dyno sheets on this setup?:corn:

It looks good but that is all I have heard or read so far. Would fit the bill for me if they were quite and did what they say.

I run with the SuperTrapp Supermegs 2into1 pipes. They are on the some of the quietest pipes I have ever heard (them or the White Bros E-Series are the pipes most people recommend if you are specifically looking for quiet), and make very good power. Click on the links by my signature to see what they look like. The pipes that make the best power are generally 2into1 and usually they are quieter and have a deeper sound than 2into2 pipes.

P.S. My pipes come in chrome but I had them heat treated black.
