    Very nice video. Another aftermarket catback and this one doesn't require welding!

    I have the flowmaster exhaust but I hate that the check engine is on.

    hellcat562 then your actuator spring isn't in right. Or the actuators are swapped side side.

    This thread should be re titled exhaust actuator video there is no valve they just built a mount with actuator stops. To prevent codes.

    I followed the video instructions 5 times and still getting a cell. Couple of friends also gave the check engine is just frustrated. I will just switch to borla once available.

    Wierd did you validate the actuators are correct side...side by part # and have the codes cleared? What codes?

    hellcat562 I'm quite confident I a fix for your issue first I'll call Flowmaster tomorrow. I'm about 95% confident. They'll test then probably re issue instructions on what to do but it would help if you told me specifically what codes you have thanks. (You'll like be up and going in minutes minus codes un less you need to clear them which I dont thunk so...)

    I wasn't expecting that code.

    If you don't have P121B as well, actuator 1 isn't working actuator 2 likely is.

    Did you validate the actuators move post install? Your close to working.

    This would require 2 people. You need to be under the car and try to see or observe if the actuators move when the car starts. Upon startup they'll calibrate (move stop...stop.) Based on the flowmaster mount I think you could tell.

    I suspect actuator 1 is froze in position. But 2 is ok.

    In the oe exhaust the actuator spring is compressed against the valve piece and that whole piece moves.

    On Flowmaster the spring rests against an immovable surface, under compression (not the best design since the spring has to move, but is workable.)

    Try adding 1 additional washer under the standoff mounts on actuator 1, and ensuring nothing like a surface blem is causing the spring to bind. Some (very) hi temp grease wouldn't hurt either. Backing off the spring pressure is probably your fix. 1st see if it's bound if you can but of not try the washer adds to remove some pressure and perhaps the grease. Your very close don't give up.

    That's a great solution.

    I don't recall if valve / actuator 1 is driver or passenger side, fnkychkn ?

    hellcat562 Once you know what side actuator 1 is, to test this you could remove it. then try to hold stops against the spring some way, if you start the car with the actuator out, but still plugged in, and can find a way to stop its movement like the flowmaster tabs do, in about the same locations, once the actuator calibrates, at some time interval I'm pretty sure the code should clear on it's own. That would confirm it's bound in the mount but pretty sure that's your issue good luck and report back.

    try just backing off the mount srews by a half a turn just enough to relieve a little spring pressure before you completely remove it. And maybe spray a shot of lube (best to be hi temp but for a quick test that wouldn't hurt, again to free up the spring to move. Then see what happens. I'll IM my mobile # to you feel free to call. If I can take it I will if it rolls to VM leave a message. Also my email.
