I have a 1997 springer with drag pipes on it and I installed power cones in the pipes, but it is just to loud so I purchased baffles for it. my question is do I need to remove the power cones before I install the baffles?

 

No.
You do not need to remove the power/torque cones. I had drag pipes on my bike for the first two years. They were 1-3/4" OD which made them about 1-5/8" I.D.
There wasn't hardly any selection for aftermarket baffles that would fit. I tried 2 different brands, but neither seemed to make much difference in the exhaust level.
I finally switched out the exhaust for a 2 into 1 Fat Cat which I just put the quiet baffle in.
It is still a lot louder then stock but no where near as annoying loud as before.

If you decide to change out your exhaust, you might look into a SuperTrapp exhaust.
There is a write up on them below you post.

I am going to try the baffles and if its still very loud my next move is to change out the pipes. who did you purchase you pipes from?

 

I have had my Fat Cat on for over 5 years. When I bought it Eastern Performance had the best price.
When I tried to quiet my drag pipes I made some lolipops that are basically big washers that you install at the aft end of the pipes. You can adjust them by rotating them to give more or less exhaust blockage. Their purpose is to add a bit more back pressure to aid in low to mid range torque. I didn't notice much difference in performance or exhaust volume.

The best baffles I could locate that would fit 1-5/8" I.D. pipes were Khrome Werks HP drag baffles. That was 5 years ago and at that time I did a lot of searching.

thanks for your help, I am going try the baffles and like I said start my search for new pipes.

 

just to let you know I did buy some baffles from J&P cycle and they made a world of difference in the sound and performance of the bike. I'm very pleased and most likely will leave the drag pipes on the bike for now. Again thanks for your help.
