Im getting ready to do manifolds and risers on my 32 fever, twin 502's with the silent choice type set up.

My question is, how much difference in sound would the silent choice version of manifolds be vs if I ditch the factory silent choice set up and run straight through manifolds and risers? Not looking to do headers.

Thanks

I will be about the same as when you are running with the silent choice open.
Maybe a just slightly louder with longer risers that dump water farther back.
