    DIY powered exhaust cut out

    There is a fine line between moron and genius and I'm pretty sure which side this falls on...

    The saga starts when I noticed a a 3 1/2" elbow that happened to be sitting on the counter at NAPA.


    That sparks an idea. This would be so much better than my 2 1/2 manual cut out that doesn't flow very well.


    So I hunt on ebay for at least a 3" throttle body.



    Then out comes the welder to put them together.



    With a header flange I attach this monster to the side of the muffler. I also put a scoop at the back to direct air down the cut out.



    I try to hide it so it won't show.


    Now how to make it move I happen to have a control cable laying around so I route it up to the drivers seat.


    PROBLEM! The cable control is really hard to pull and won't keep the throttle flap open with the spring in it. When I put less pressure on the spring it won't seal shut. Time for a plan B and where intelligent design kind of fall apart...

    I cut apart a Camaro door to get the motor out.


    Weld said motor in the trunk with a hunk of cable welded to the gear.



    Run the cable through the floor and a pulley to the throttle - er a no the cut out.


    Wire it all up the a Camaro power window switch


    And voila an electric cut out for 34 bucks. Click HERE to hear how it works.
