Stupid question about baffles for Rinehart exhaust

I really hate to ask a stupid question but how else am I going to find out an answer to a stupid question. I bought my 06 Ultra about 18 months ago and it had Rinehart true duals already installed on the bike. I like the sound, but my wife when she rarely rides with me thinks they are too loud. I see the baffles for sale on their web site (for about $125. ouch), but if it would keep the wife happy a cheap price. What I want to know is how big of a deal is it to put these baffles in and out and how well do they work. Thanks for your help.

You should use a screw in slide hammer. Just thread one end into one of the baffle holes and hammer it out. I tried to drive it out from the upstream end with a drift and it would not come out.

As are with most true dual exhaust, if the baffles are removable:
-Remove the outer end caps. Usually one screw at the top or bottom that holds the cap to the actual pipe.
-There is usually another screw on the bottom of the pipe that holds the baffle in place. Remove it.
-The baffle should with some persuading, come out as one unit. You may need to clamp some needle nose vise grips and tap on the pliers with a hammer to get them out, but one you get them started moving they should come on out easily. Generally there is only one point of contact from the baffle to the pipe (at the point where the screw is).

NOTE: I too, at times wish I had a quieter ride. I have Rineharts on my ultra with the stock baffles. They sell a "quiet" baffle, but i have read somewhere that this quieter baffle will reduce the exhaust pressure which will reduce the torque/HP slightly. Theory is, reduce the niose, you have to have a trade off for power. I read that a guy (sorry I cannot locate the link on this) had his bike dyno-ed with the stock baffles then with the quite baffles and the power loss was 5-7% and the bike was 5-10% quieter as measured with a decibel meter. I think this sounds accurate. It is not worth the loss of power to get 5% quieter. Not for me.

RineHarts are fairy quiet, not as quiet as HD stock, but more so than some. On a 500 mile day ride, the drone of loud pipes really hampers my pleasurable riding experience...just my opinion...others like the screaming, roaring pipes and for them that is good also. I call these the "look at me riders" as most are going from tavern to tavern and the noise does not concern them...mainly because "momma" is home and not complaining about the noise either. LOL! Not to open a can of worms or steal this thread...just my humble opinion and viewpoint. The older I get the more I am concerned with comfort and safety rather than bling and the "wow" factor. Try ear plugs, they work to deaden the sound and you can still hear the engine and external noises. They also make the long riding day/week more enjoyable, at least for me they do...plus you can still hear the intercom and the radio via the helmet headset.

The baffles are very easy to change, remove screws, remove end cap, remove baffle by wiggling side to side and top to bottom. I have the quiet baffles in mine, and they did make a difference in noise (does not bother me now on long trips), but not in power, I picked up low end torque..

Also it helps to soak with penetrating oil.
