Default Big Radius Baffle Modification

I know the topic of V&H Big Radius pipes comes up often, and I apologize... With that, I removed my baffles last night and had some questions. First, the sound is really odd. It sounds like an old muscle car, not a motorcycle. Next, as expected I lost low end torque. With that, I'm curious have any of you modified the OEM baffles? If yes, how much did you remove and what was the impact to the sound?

I did the same thing but ended up buying the Big City Thunder Monster Baffles. It got my back low end torque and sounds great.

I bought the BCT baffles for my big radius pipes and attempted the install yesterday as well.

Problem was the first baffle came out with no issues but the second one would not budge. at all. even after applying heat. Any ideas on what to do? I didn't realize the stock V&H baffles were so long.

My suggestion would be not to mess with the stock baffles. I have a friend who did the BCT's and they work and sound awesome.

still curious if anyone has modified the original baffles... With that, which BCT baffles did you buy? They seem to go on diameter, however I'd assume the BR's need a curved baffle?

As far asI know they make one espicially for the BR pipe because of the curve

Spray the baffle with WD-40 and let it soak for a bit then take some needle nose pliers and work that bitch loose , that's what i did and it came out ....

BCT baffle is not curved. It is a hair smaller diameter. It also has to stick in the pipe further. You will have to drill new holes in you pipes. No big deal though, I just removed both heat shields and did it with the pipes still on the bike.
As far as removing the stock baffles....I used a seal puller. It worked great.

I would think that if you open the pipes by removing the baffle your gonna lose a lot of back pressure causing your A/F ratio to shift as well so you would have to re-map your ECM/ fuel management module to compensate.
