So my exhaust is/was pretty loud, I had hooker lt's running straight back to a magnaflow di/do muffler through 2.5"pipe with turndowns under the bed.
Now I like the exhaust dumped/cut off and it sounded good, just way to loud on the highway. SO I figured adding a second muffler should quiet it doun right?... nope its slightly quieter but not quiet enough.. sounds wayyy smoother but still loud.
so I had an idea. adding headers killed my low end torque and I like the torque for pulling and such, what I want to do is add a cable/servo controlled butterfly valve in the pipes. this would close up at low rpms and bring back some of the backpressure/torque and open up when it needs to breath.
It will also make it quieter and possibly help the mileage a bit (lugs on the highway right now)
Anyone see any problems with this.. it would basically be a throttle plate in my exhaust pipe, likley a diferent shape so it dosent catch on the not so smooth exhaust pipe and with a much bigger hole when its closed.
I though that even one with an actuator that was either all open or all closed could work too, since I have a plethora of pneumatic actuators and onboard air already.
