What concerns would there be with removing just one baffle out of HK 3" pipes? I am thinking.. (there is trouble in the making) one in and one out may give a unique sound. What do the tech guys say about this.....
It's my understanding that running with only one baffle would create unequal back-pressure in the engine. I could be wrong. Perhaps someone with more mechanical knowledge could provide more information.
Why not remove both baffles, unwrap the fiber material surrounding the baffles, and then reinstall them?
That would give equal back pressure and the louder sound that you
probably think you want. Don't forget to wear earplugs to protect
your hearing so that you won't need hearing aids in your old age.
Also, you might try replacing the fiber baffle material with stainless
steel sponge from the cleaning section of your local grocery store.
This is assuming that the steel sponge can fit between the outside of the
baffle and the inside of the pipe. Steel sponge is looser than
fiberglas or ceramic wrap, and won't load up with carbon as easily.
Steel sponges usually sell in a package of two for $1 to $1.50.
I would estimate that between eight and a dozen sponges would
be needed for one baffle, twice as many for two.
