    New Hellcat owner couple of weeks ago. Exhaust at low-mid throttle resonates in the whole cabin, no issue at idle or WOT, kind of like too much bass from the sub-woofer. Love the car, exhaust from the cabin sounds like a tin can ricer. I know its not going to lope like the built 426 in my 65 Sport Fury, but this is ridiculous.

    Suggestions for aftermarket exhaust system that is low and throaty?

    Congratulations dammstrate.....welcome to the club. Wonder if you might have something unique going on like an exhaust leak.

    Welcome and congratulations on your cat! I would have the dealership take a look at it because this doesn't sound normal. Just my opinion:)

    I think you have some particular problem with your car. I have no such resonance in my all stock HC.

    might wanna try a active exhaust simulator delete... im doing mine today.. there is a thread or two on it.. it lockes the exhaust valves open all the time and can be simply returned to OEM in a few minutes.. the cats are way too quiet under 2k rpm from the factory

    Installed a Solo Mach Shorty exhaust kit (they are a supporting vendor on here) and I can't get enough of it. The sound is great during normal driving and there is no drone at cruising speeds, but at Wot it is wicked! Although I do agree with everyone else who thinks there is a specific issue with your car's exhaust, because what you are describing is not normal.
