Active exhaust actuators part number??

32816 Views 47 Replies 9 Participants Last post by  HellaciousFish
I recently purchased a 2015 Challenger Hellcat and the previous owner installed a Flowmaster exhaust, (I don't which type).

Anyways, the previous owner cut the active exhaust actuators completely out, and just left the lines dangling... it's no problem to drive or anything, I just hate seeing this stupid MIL light. Plus I can't remote start my car for longer than 10 seconds before it shuts off because of the light.

When I bought the car I didn't think finding these parts would be this difficult , but it is...

Does anybody in this forum know what the part numbers are for the left and right active exhaust actuators?

I would.loke to purchase a left and a right actuator and then get the AES kit and install it that way.

Any help will be much appreciated

You ever get anywhere else with getting this finally fixed man?
Long story short, I'm living with the check engine light on...

I will need to order new actuators and springs/coils to correct the problem...

It doesn't bother me too much, so I haven't done it yet

Why not buy a set from a wrecked hellcat? Call Tim Mulcahy at Clevland PaP and see what they can do for you. 866-236-5031

I’m going to eliminate mine as soon as I can... need to weld the valves open and remove the actuators.

After some aging, every now and then if they stick you get a CEL. I’m on my second Hellcat and already seeing them foul up on occasion. I already turned off the codes in my tune.

Also, they are only there for EPA noise requirements... they are not there for our enjoyment at all. They are an extra, useless thing that can only break and cause problems.
Ok, ordered it, and it finally got here, I hooked it up and it was giving me the p1217 and p121b codes...

I used the Autel OBDII Scanner and cleared the codes...

I turned my car on and off several times so far, and the MIL has not come back on, (again, thank you Chimazo!).

Now the question I have is, how long, or how many times can I start the car before those come back on?

Also on the scanner, it is telling me the p1217 code is for a fuel solenoid, not driver side exhaust actuator.

The p121b code tells me to refer to the owners manual.

Idk, I'm just happy I can remote start the cat again!

Yep those are the codes for left and right. I was getting them too and finally turned them off in my tune. Hate those actuator/valves. Can’t wait to get mine taken off... I’d do it this weekend if I had a lift and knew how to weld.

Who did you take you cat to for the tune? A speedshop, dealer, mechanic...?

SeriousHP in Houston built and tuned my car. They use HP Tuners VCM Suite for tuning. In the tune file, under diagnostics, you can uncheck those two trouble codes and they will no longer show up and cause a CEL.

You can uncheck any trouble code with HP Tuners VCM Suite for that matter.

You could do this yourself, but you would need to buy the VCM Tuning Suite package, and a second PCM unlocked for tuning. If you are ever going to have your car tuned, it’s inevitable anyway, and most tuners I know of are using HP Tuners, or moving towards it.
Goodness, anyone have any idea why in the world the left sided (driver side) actuator is more than double the cost of the right sided one? Seriously. WTH Dodge. It is the same part basically.
