Which performance exhaust systems work best for the Dodge Challenger?

Hey everyone! I’ve been a proud owner of a 2021 Dodge Challenger R/T for about a year now, and while I absolutely love the car, I’m finally ready to give it that deep, aggressive growl it deserves. The stock exhaust is okay for daily driving, but it feels a bit too muffled when I really step on it. I want that classic American muscle sound that turns heads without sounding like a tin can.

I’ve been doing a ton of research, but honestly, I’m getting a bit overwhelmed by the options. I’ve looked into the Borla Atak, which sounds incredible in videos, but I’m worried it might be a bit too loud for my neighbors early in the morning. On the other hand, the Corsa Sport seems like a great middle ground, especially with their no-drone technology, which is a big deal for me since I do a fair amount of highway cruising. I’ve also heard some people swear by a simple mid-muffler delete, but I’m hesitant to go that route if a full cat-back system provides better performance gains.

My budget is around $1,200 to $1,800, and I’m looking for something that offers a crisp, deep tone at idle but really screams at wide-open throttle. Performance is a factor too; I’d love to pick up a few extra horsepower if possible, though sound quality is my primary goal. I’m also curious about fitment issues—has anyone had trouble installing specific brands on the newer models?

For those of you who have upgraded your Challenger's exhaust, which system do you think offers the best balance of aggressive tone and daily drivability, and did you notice any actual performance improvement after the install?

yo! congrats on the R/T, honestly that 5.7L hemi is such a great engine to work with. i was in your exact same shoes about six months ago with my 2021. i wanted that roar but didn't wanna annoy my neighbors at 6am lol.

i ended up comparing a few setups and here is what i found. first, i looked at the Borla ATAK Cat-Back Exhaust System 140650 and man, it sounds MEAN. but tbh, it's pretty loud for a daily driver if you're worried about cold starts. then i checked out the Corsa Sport Cat-Back Exhaust System 14405. i actually went with the Corsa because of that "no-drone" promise. i do a lot of highway driving and i can confirm there is literally ZERO drone at cruising speeds, which is huge.

Corsa vs Borla:
- Borla ATAK Cat-Back Exhaust System 140650: Pros: loudest, very aggressive. Cons: might be too much for neighbors, more expensive.
- Corsa Sport Cat-Back Exhaust System 14405: Pros: perfect balance, no drone, very high-quality fitment. Cons: pricey but worth it for the cabin comfort.

i also thought about just doing a mid-muffler delete (super cheap, like $150), but i was worried it would sound kinda raspy or "cheap" later on. plus, the full cat-back system gave me a noticeable, though small, bump in throttle response. it just feels smoother now. the install on my 2021 was basically bolt-on, no real fitment issues at all. if you have the budget, go with the Corsa Sport Cat-Back Exhaust System 14405. i'm super satisfied with mine! gl with the build!! 👍

Story time: I went through this exact same dilemma last year with my R/T. I basically obsessed over clips for months because I wanted that SCREAM at wide-open throttle without my wife killing me for waking up the kids, you know?

I was looking at the Borla too, but honestly, the price tag was a bit steep for me. I ended up going a different route to save some cash while still getting that premium muscle sound. Here is what I learned from my setup:

* I eventually landed on the Flowmaster American Thunder Cat-Back Exhaust System 817739. It’s got that deep, classic chambered muffler sound that just feels right on a Hemi.
* If you want something super crisp but slightly cheaper than the big names, check out the MagnaFlow Street Series Cat-Back Performance Exhaust System 19227. It’s very civil until you floor it.
* One pro tip: I spent about $100 on Dynamat Xtreme Sound Deadening Liner for the trunk area. It LITERALLY eliminated the minor drone I had during highway cruising.

Basically, you don't HAVE to spend $2k to get a great tone. I saved enough for a cold air intake too! Good luck dude!!

Honestly, I’ve found that doing the install yourself is the way to go if you’re trying to stay within that budget. I spent a weekend under my R/T last year putting on the system I ended up with, and while it was a bit of a workout, it really gives you a better feel for the car. Most of these bolt-on kits for the newer models fit pretty well, so you don’t usually need a professional shop unless you’re dealing with welding. My main tip is to make sure you’ve got some solid ramps or high-lift jack stands—trying to shimmy a long mid-pipe into place while lying on your back is basically a gym session lol. Plus, you save like $200-$300 on labor which helps if you're eyeing those higher-end setups. Just watch out for the active exhaust valves if yours has them; they can be kinda tricky to swap over without throwing a code, but it's totally doable with some patience. For me, the DIY route was super rewarding and the fitment was spot on once I finally got everything lined up right. Tbh, there's nothing like that first cold start after you've bolted it all together yourself!
