    I've had my 2015 Hellcat Challenger over a year. Great car for the money and a good daily. Previously I had a 2012 SRT8. I had a Magnaflow exhaust on it and it sounded weak IMO.

    But, I own a 493ci 69 Charger with 2.5" mild steel and glasspacks. There is no comparison in sound. (I know, I can't expect the modern car to sound as good, fine). I'd say we're talking 20 - 30 decibels difference at warm idle.

    I don't believe the track or sport mode makes any difference to the valves no matter what other people say. The valves simply close at low RPMs and this is not a muscle car sound. Sure it's OK at WOT (although the blower is quiet as hell).

    I have a 2014 Ferrari 458 and all I did was take off the rear diffuser and unplug the valve cannisters then plug the valves with bolts. This mod was like night and day. Even finicky Ferrari are even happy with this under my warranty. They even tidied it up for me at my last service. So what gives with Dodge making a quiet 707 HP car?? Please don't tell me back pressure and forced induction.....

    ------------

    Rant over, sorry... I'll get to the point. I don't normally get emotional with first posts. I just want my big ass sublime green 707 hp car to be heard coming when I'm going through town without having to artificially shift gear and blip the throttle like a moron.

    SO, has anyone found the solution yet? I've searched 3 hours tonight. Pulling fuse 36 and dealing with the warning light seems like the best option. Can I just leave the fuse unplugged or am I going to cause issues?

    I want to pay someone to get this done.

    If anyone has an update to the current situation I'd really appreciate it.

    I'd prefer not to have cut outs and having it sounds like a machine gun. Let's just get rid of this stupid valve!!

    PS on a similar subject, any quick mod to make the supercharger more audible?

    If you want noise I highly recommend the mid muffler delete. It's fabulous.

    I read about that, I assumed it would still be quiet for some reason. So I just get the exhaust guy to remove the front 2 mufflers and weld in pipe?

    Doesn't it still go quiet at idle?

    Sorry, I just reread my first post and came over quite frustrated/disbelief.
    Thanks guys

    Great! I am diligent with search before joining a forum but I'm now glad I joined.

    Do you happen to know the part number? i'm in the UK you see and don't want to order the wrong part from summit (it costs more to return it than cut the loss usually)

    Its about how much you're willing to spend. Taking control of a lin slave isn't tough. Duplicating its code isn't rough either. If you use software that comes with most analyzers out there. And spend some time learning lin. But acknowledging the ecu during start up and then running diagnostics drives up costs significantly, it did for me anyway. For me that meant either building or finding something that would act as both a lin slave and master. I did the latter. But it wasn't viable for resale based on materials costs. Not yet. Not just for valve control.

    Borla has a valve delete (fool the cpu) option.
    Not sure of part number, but check their website or give them a call.
    I found them great to deal with.

    I have noticed that when I'm going down the highway if set everything to track mode from the default mode the volume of the exhaust will increase a little. Any combination of the setting other than that doesn't make difference.

    ;
    Website checked!
    They indeed have an option, but after scouring the internet I see no photos anywhere or description of how it works,
    I'm willing to bet it works like the Flowmaster design, a spring that loads the motor to fool the cpu.

    I notice a big difference between street and track exhaust sound....but this is a factory exhaust and just wont sound like an old school car with glass packs and no cats....but to me it is the best sounding exhaust of any factory car I have owned...even better than most aftermarket exhaust.........and WTF are you talking about "although the blower is quiet as hell)".......LOL.....this isn't you Bo?.....

    I don't think he knows what the supercharger sounds like if he says he can't hear it.

    Thanks, still sounds a bit beyond me to be honest :( I doubt I'd find anywhere in the UK to do that for me. I think we only have a dozen hellcats here.

    Thanks, will make a contact, but before I do does this mean fitting a whole exhaust system? That's all I see on their website
