Why don’t you try removing the Helmholtz resonator before swapping out the exhaust, that’ll make it louder. If you want some drone, that’ll probably do it.
I've had a lot of different cars and sport / race exhausts and honestly I wouldn't change this setup unless it actually improved performance... its great the way it is, not too loud but BAM loud when it matters. Love it. I have an Eisenman Sport on an E55 which is very similar in range... from docile to barking in your face. Loud all the time with drone gets old quick.
Congrats on the sweet ride! I'm still waiting on my TH, but I've already done some research. At this point the only system I would consider would be the GTHaus. However, I was just looking at the website today and the axleback component appears to be soldout (pre-orders available tough). There is an X-pipe component sold separately that eliminates the resonator. I'm guessing this would be quite loud with the valve switched to open. You should check out some videos of the GTHaus on the 6.4L GC...quite aggressive. Anyway, good luck with your search.Anyone know of any aftermarket exhausts for the Trackhawk? Just picked mine up tonight and love it, but feel a missing mean sound!
Is the stock exhaust that lacking? Most of the vids I've seen online, indicate the truck gets pretty loud when you stomp on it. I suppose if you are looking for the constant drone, that you wont get that on the stock set up. Not sure if its really worth doing resonator/muffler deletes as they wont provide any boosts to performance. Let me know if you do find something more to your liking.
So, options currently are any exhaust that fits the SRT. They have the exact same exhaust setup. Solo Performance makes a nice system that is cat-back as well as Magnaflow. The biggest restriction is the suitcase muffler. The only thing the GT Haus system gives you is the ability to make it real quiet unless you also pay to have their X-Pipe installed.
The only Helmholtz resonator we have is on the intake. Removing that makes the supercharger whine loader. This does nothing for the exhaust note.

I removed the Heilmholz and honestly cant tell much of a difference
i 100% agree with the OP
- put a magnaflow on her...and it helped..ive called K nN AFE, etc..they are working on a CAI but they dont have anything yet..
i am installing exhaust cutoffs ahead of the cat with a dashboard switch that is supposed to make it sound wicked...spoke to mopar service mngr about it, he said as long as its ahead of the cat, no warranty issues..(that is/would be a deal killer to me)
i'll post sound when it's done..
so far, all i hear is the supercharger whine...
but if you are outside the th and behind it, it does sound ok..lol

Do you mean after the cats? Installing before the cats will throw a check engine light.i am installing exhaust cutoffs ahead of the cat with a dashboard switch that is supposed to make it sound wicked...spoke to mopar service mngr about it, he said as long as its ahead of the cat, no warranty issues
- yes, after the cats...i have ZERO interest in ANY mod that will generate a light or a flag on warranty...Do you mean after the cats? Installing before the cats will throw a check engine light.
For any that might wonder, I went ahead and had the center suitcase resonator cut out. Crazy loud, might even be too loud!! Some days I like it, others I feel like its pretty obnoxious. Definitely need to get an 'x' pipe back system of some sort.
did it throw a light??

But, that only replaces the rear silencers and not the suitcase muffler (for $3k). If anything is a restriction in the system, it is the suitcase. Plus, that thing weighs about 35 lbs.GT Haus makes and Awesome Exhaust System that will be shipping soon..
I should be getting my Solo Performance exhaust soon and I am going to weigh the stock vs. the Solo and post my results.
Post a sound clip also. I do not know why others that have already changed out the exhaust have not post any sound clips.

Do you a sound clip? I was thinking of a Magaflow also.

Check out stainlessworks they have a great system cat back or full system including headers and hi-flo cats
I have to 2nd this, and have some experience to share... may not be 100% relevant, so YMMV.Check out stainlessworks they have a great system cat back or full system including headers and hi-flo cats
I had a '15 GC SRT and added a 6lb blower to it, and along with that, installed SW long-tubes _with_ hi-flow cats. I left the stock cat-back exhaust. I did not want it LOUD... I wanted improved performance, especially since I had added the supercharger. I figured it would be a little louder anyway. Unfortunately, I have no exhaust clips from that vehicle, and I do not know if it would sound much, if any, different on a TH. But it sounded great. It was noticeably louder and throatier (good sounding) than OEM, but it was quiet and not obnoxious at all (zero drone) when just tooling around. Idle noises and cold starts were excellent.
I would rate that setup above the OEM TH as far as audible enjoyment. Although the OEM TH exhaust sounds better than the WK2 GC SRT exhaust. Therefore, I don't know if I'm going to add SW headers or not. It's not cheap. It's cheaper than the GT Haus catback however. But if I'm not going to gain performance from it... then I won't spend the $$.
Just wanted to add my $.02. I think most of us buying this particular vehicle want some semblance of normalcy when just cruising around. We want to be able to listen to the HK stereo, talk to passengers, order drive-thru without shutting off the engine LOL, etc. But its nice to have more exhaust pop when going WOT. I found adding headers/hi-flow cats to a GC SRT did this in spades. My educated guess is it would do the same for the TH (and won't throw codes!). Just another option to consider.
