I bought the KC international megaphones which are a knockoff of the cfr.  I tried a set great sound but bad tuning issues. I decided to do what I used to. build a restrictor plate.  I bought the KC int. knockoffs and they sounded great but lost torque and started missing real bad. I drilled the end cam and pulled it off and made a 3inch aluminum plat with a 1.75 hole in the middle and put the caps back in.  it maintained the deep sound but I got my torque back and I love these things. easy fix started thinking I used to make my own baffles for my triumphs sporties and trouble heads in the 70's and 80's

I think that using some big city thunder baffles would work also...it may take some trial and error to ge them in the sweet spot but...for those that have to have that CFR sound...without the torque loss...

Can you post picture with the added plate.
Sounds deep, but changed, did'nt it ?

Thanks

Hello Jagonza1,

I love to see some pictures of the added plate.

Thanks

They may work but I talked with several tuners and they said stay away from the head pipe baffles. they say you may get a little torque back but the restriction is a horsepower killer. the all recommended doing something in the end of the muffler. I like the 1  3/4 hole in the plate but I am going to try a 1 1/2 hole next. quieted them down a bit but still very deep tone
