    I picked up the Borla ATAK cat-back exhaust for my Challenger Hellcat. While I have installed a few exhausts in my day, I have never had to mess with the transfering of exhaust actuators. The instructions are extremely vague on exactly what to do: (http://www.borla.com/140646.pdf).

    I have seen the flowmaster video where they describe the level of care needed when removing and installing the actuators with their exhaust install. Has anyone installed the Borla exhaust and if so, is there any advice you can give me to put my mind at ease? Bottom line is I want to avoid a CEL......

    Any help would be appreciated.

    I looked at the attached file. Seems pretty straight forward. Unplug and unbolt from old system and add to new system with supplied hardware. Shows that actuators go on Borla system with three clips and matching bolts per side. Might be a little lacking in positioning informaiton for actuator ams but with car cooled down, they should be back in normal postion. Bolt them on and plug them back in.

    I believe its just the chambers of the mufflers used. I think everything else it the same.

    Please shoot a couple of pics of where the actuators attach prior to mounting them, and share them. Thank you.

    Here is the flowmaster video I referenced in my initial post where they discuss swapping the actuators:

    And here are the pics requested:

    I found out the difference from borla


    Hi,


    One has MDS valves, while the other, has valve simulators to eliminate them.

    The 140646 has valves and the 140648 does not.

    Great info, thanks for sharing. Looking forward to hearing your impressions of the Borla ATAK, once you get the install done.

    This was there response to why to choose either or system

    It’s for folks that want to modify the car even further. If the valves are in place, and too much boost is added, it will most likely blow the engine.

    So does the 140646 kit come with new replacement valves installed on the kit? And the kit # 140648 with the "simulators" just not designed to use them and have brackets to relocate or just move them so they are plugged in for no cel? I mean it's about 500$ difference between the two and it's just kind of vague.

    I can confirm the 140646 comes with the replacement valves installed on the pipes. I hope to have time this weekend to install the exhaust. When I ordered mine, I had no idea there were two part numbers for the same sound level (ATAK); I thought all Borla exhausts deleted the valves inside the pipe and was surprised when mine came with them.

    Hopefully this doesnt quiet the exhaust down too much. The good news is the section of the exhaust with the valves installed is easy to take on and off the car. I figure if I get it on and its too quiet, I may just take that section of the pipe off and either drill the holes in the flaps out larger, or even perhaps manually remove them entirely. It does kinda suck I paid $500 extra for something I honestly didnt want, but it is what it is... Borla really should have done a better job writing their product descriptions.....
