So I'm looking into aftermarket exhaust systems for my 2021 charger hellcat. I know some guys have full exhausts some with cat backs and some have mid muffler deletes etc. I'm not looking for anything ungodly loud. I want to retain the clean sound that the stock exhaust has but just a little louder. What are you guys running?

I have borla atak catback. Nascar loud when on it. Cool and calm nice tone when crusing. Seems to be one of the loudest exhaust for mopar and maintains factory tone without any rasp.

AWE tuning makes some very great options with a track or touring option depending on what you want. A newer system that also looks nice is the MBRP Race cat back which also comes with some nice carbon fiber tips. Main difference between these systems is that AWE uses a H pipe for a deeper classic muscle car tone while MBRP uses an x pipe which is a bit higher pitched but both sound insane and are 3 inching diameter, 304 stainless steel, and come with simulators to delete the active valves. MBRP will run about 1100 and AWE will run about 1600. Comes down to preference if you want a deeper tone or higher pitch but both systems are top notch quality and sound bonkers.

@392Ant is correct. I have the AWE Track edition installed on my Hellcat Charger. I love the sound and so do many other people. I get lots of compliments.
I am posting the link to HHP's web page because there is also a Touring edition that you would probably enjoy having. BTW there is no Drone

I have the Corsa Xtreme catback for my Charger HC. BEST purchase for my vehicle hands down

I went back and forth with a few different exhaust's I ended up with the Borla Atac. Very happy with it good quality and mellow until your on it like Wellsboy said.

Just bought my buddy's Borla Atak and he conveyed the same thing. It can be as quiet as stock but your right foot is the volume control. It does go to 11.

 

[Epat]

Borla Atak is obnoxiously loud

PERIOD!

Exactly what I was looking for. Thank you!!

Swap mid mufflers with Vibrant 1794 is the cheap choice. AWE Resonated Touring Exhaust is the more expensive choice.

What do you guys think about leaving a stock exhaust and going with a set of headers?

I had considered the resonators initially. Or even pairing them with the awe track to see what type of sound I can get with that

On a related topic, the exhaust manifold is pretty tight on the HC and I was thinking of installing a kooks long tube headder, has anyone measured the difference in Torque/HP after changing out the exhaust mainfold?

Below is from a test they ran on a 6.0 "BluePrint" small block with some upgrades.

"It’s pretty much a given that the long-tube headers will net the highest peak-power rating, but the purpose of this test is to find out just how much of a difference there is between the different style headers.

Below you’ll see just how much power the engine made with each setup:

• Log-style, cast-iron manifolds : 474.2 hp @ 5,700 rpm / 453.2 lb-ft of torque @ 5,400 rpm
• Mid-length headers : 488.2 hp @ 5,700 rpm / 464.3 lb-ft of torque @ 5,400 rpm
• Long-tube headers : 494.5 hp @ 5,700 rpm / 474.3 lb-ft of torque @ 5,400 rpm"

It would make sense if your changing out the exhaust then go ahead and tackle the manifold at the same time, if you plan on doing that also.

If anyone is looking at cutting weight, what does a carbon fiber exhaust save over Stock OEM? My buddy is trying to figure out just how light he could possibly get his Challenger so I'm coming up with "creative" ideas.

Carbon Fiber exhaust pipes?

 

[392Ant]

Carbon Fiber exhaust pipes?

If this in reference to my post not carbon fiber pipes that one I never heard of. But MBRP with their race or street cat back offer a carbon fiber quad tip option for challengers or a 5 in carbon tip for chargers the pipes are t304 stainless steel.

The rasp is what some like to avoid.

Others, however, seem to just LOVE the "Tijuana bus iron sewer pipe" sound of the exhaust.

And, yes, I have heard that, in person, in Tijuana, that used just iron sewer pipe for exhaust.

 

[HellcatHellYeah]

To be clear, I haven't seen or heard of anyone that has a full carbon fiber exhaust in a car but they do make them for high performance racing bikes. The tips are aesthetic only I think. The thermal properties and strength would make carbon fiber an ideal (if costly) replacement being far lighter than metal (about 70%) and Alum (40%). More theoritical exercise than practical alteration, simply a matter of weight reduction. I believe the exhaust weighs around 55 lbs (?) and you could cut around 35 lbs (gain of about roughly 3 hp at 100 lb loss equals 8 HP gain but when your're looking at everything...). Just how light can a 17' challenger 392 Scatt Pack get?

My buddy pulled his cats and what a difference it make in a good way

 

[Hellcat1701]

I started with just swapping the mids with the vibrants. That was fine for a while but I wanted more
After I did my stage 2 dusterhoff tune I wanted more
So I went with the AWE non resonated touring system with black tips.
I love it!

Be more creative!!!
