    has anyone install long tube headers? If so which ones, and is your car lowered?

    I'm concerned with long tube headers and getting them since my car is lowered.

    Other than sound, we have proven on Linda's car there is NO performance gain, the OEM headers flow very well as she has done 9.71, use the money in other mods for performance.

    sinister707...Thanks for posting this thread!

    Top Cat....I'm glad that you responded. I was considering long tube headers ONLY for the performance gains
    but I do not want the car any louder, especially on the inside of the car. I was skeptical of performance gains
    and not sure if I should pull the trigger or not. Your thread just answered that for me. I like the way that the cars
    sound with the factory exhaust. Since you are not trying to sell headers to me, and you have first hand knowledge
    and two super quick cars to base your opinion on, I'll spend my time and money looking elsewhere for power.

    So, thanks to both of you!

    No, for me at least, the Hellcats are not fast enough. I'm always looking for a little more, but that's me not everyone wants more. But there are a few things to do to support more power before making more power.
    Like the drive shaft and pinning the crank.

    I'm getting a game plan together so that I don't do things out of order and break something that I could have
    avoided breaking. Plus, I don't want to spend money on something that isn't going to get me to where I want
    to be with this car.

    TC, GC,

    Thanks for the info. I agree I don't want to get the car any louder on the inside. Also if there is no real performance gain don't want to spend the money.

    ReoTom,

    Agree if you want more power seems like those things you mentioned seem like the way to go.

    My list will now change to the following:

    BWoody sway links
    the cross brace (forgot with this is technically called)
    Pulley
    3.09 rear
    DSS DS (aluminum; or maybe CF)
    Tune (to go with the pulley)
    Wider tires
    and ???

    Open to suggestions.

    So the question is, What WOULD you invest your hard earned cash in to improve the performance of the vehicle. A list in the order of most to least important would be helpful. Appreciate your insight!

    Driveshaft swap and pinning the crank are things that FCA needs to do for the 2017 Hellcats. Seriously.

    I am being told that Pinning a Crank voids the warrantee with Dodge. Can anyone verify this?

    Hows the crank affixed to the crank shaft now if not pinned?

    ReoTom....The crankshaft "snout" has a shoulder on it that the harmonic balancer/pulley assembly is pushed on to until it bottoms out against the shoulder. So it's a press fit onto the diameter of the crank and it's pressed on
    until it stops against the shoulder. Then a "diamond encrusted" (no joke) and a bolt are used to "sandwich" the
    pulley against the shoulder. There is not any type of keyway and key or any type of pin. These pulleys can spin
    on the crank and ruin the crank. Then it's time for a new motor. In my case, it's time for a new car.

    I hope that my description makes sense and helps answer your question.

    To add a little to what gray cat described. The diamond encrusted washer is supposed to supply enough grip, after being torqued to something like 239 ft/lbs of torque. So it's all up to the bolt and special washer to keep things from slipping. On a blower that takes 80 hp to function.
