The 300C is the top-of-the-line trim version of the Chrysler 300. Powered by the 5.7L HEMI V8, it’s one of the most potent versions among the existing 300 models, second only to the Chrysler 300 SRT8. Driving around in such a car undoubtedly makes you feel like a boss; an enthusiast with taste buds for the finer things in life.
What better way is it to announce your arrival than to get out of a muscly luxury sedan that sounds terrific, right?

Using an aftermarket cat-back exhaust system, you can drastically change how your large sedan would sound like. Regardless of your sound preferences, may it be overtly loud and aggressive or low and deep, you can be sure that an aftermarket exhaust system is that one device you’ve been looking for.

#1 Borla ATAK Cat-Back Exhaust System
- Manufacturer: Borla
- Part Number: 140637
- Sound Level: Aggressive
- Vehicle Fitment:
- Chrysler 300C (2015-2020)
- Chrysler 300C Platinum (2015-2017)
If you want to highlight the V8-powered monstrosity under your car’s hood, then you’d better check out the Borla ATAK Cat-Back Exhaust System. It’s one of the most aggressive Chrysler 300C exhaust systems available. Hearing its tone while you’re on full throttle is truly eargasmic. If you fancy loud and aggressive cars, that is. It’s one of Borla’s entries for the Chrysler 300C, aside from the S-Type, which sounds deep and low.
So what’s with the ATAK exhaust? It features Borla’s Acoustically-Tune Applied Kinetics technology wherein the perforations of the muffler’s cores are adjusted to produce a specific level of the exhaust note. In this case, it’s loud and aggressive. The system features stainless steel tubing, inlet, and outlet, all with the same diameter of 2.5”. It’s also equipped with a turbo-style muffler to reduce unwanted noise.
Those components’ culmination results in an intoxicating concert of steel, making you love driving your Chrysler 300C more. Those who already have the Borla ATAK on their cars commented that there is little to no drone present while they’re driving.

#2 CORSA Performance Sport Cat-Back Exhaust
- Manufacturer: Corsa Performance
- Part Number: 14972
- Sound Level: Moderate
- Vehicle Fitment:
- Chrysler 300C (2015-2017)
- Chrysler 300C Platinum (2015-2017)
Corsa has really dedicated a lot of R&D to make sure that their exhaust system would sound the way it wanted it to be. Just like the previous entry, the Corsa Performance Sport Cat-Back Exhaust sports an exhaust note that will leave you wanting more. Corsa is well known for providing no-drone solutions to enthusiasts who want their cars to sound classy yet aggressive enough.
The Corsa Performance Cat-Back Exhaust features a 2.5” diameter pipe with a dual rear exit configuration. There are no exhaust tips on the package, prioritizing an OEM look that goes well with the Chrysler 300C. This exhaust system outflows the stock exhaust by about 75%, resulting in some decent performance gains. Additionally, it’s 11lbs lighter than stock, which slightly reduces your car’s sprung mass.
The real beauty of this exhaust system is the fact that it’s droneless. This is possible thanks to Corsa’s Reflective Sound Cancellation Technology which eliminates unwanted frequencies that cause drones. This Chrysler 300C exhaust may sound quiet at first, but give it some time, and you’ll see that the shy exhaust will open up and start to get louder as time goes by. If it’s mild, throaty, and deep tone is not enough for you, you can fit in some long tube headers so you can see some improvements.
If you’re looking for a Corsa exhaust that’s wife-approved and doesn’t sound that obnoxiously loud, then you can never go wrong with an aftermarket exhaust like the Corsa Performance Sport.
#3 Corsa Performance Xtreme Cat-Back Exhaust System
- Manufacturer: Corsa Performance
- Part Number: 14973
- Sound Level: Aggressive
- Vehicle Fitment:
- Chrysler 300C (2015-2017)
- Chrysler 300C Platinum (2015-2017)
The usual problem fans of Corsa Performance have is whether they’ll choose the Sport or Xtreme. They find it challenging to select one from another because they’re both excellent and add a lot of value to the car in terms of improved flow and sound quality. However, Chrysler 300C owners seem to gravitate more to the Xtreme than the Sport because it allows the vehicle to growl more compared to the Sport.
So what’s with the Corsa Performance Xtreme Cat-Back Exhaust System? It’s basically similar to Sport when it comes to construction. 2.5” diameter pipes will still traverse the underbelly of your car, and it still sports an OEM look with its lack of exhaust tips. Additionally, it’s also equipped with Corsa’s RSC Technology to eliminate any presence of droning.
The differentiating factor of this Chrysler 300C exhaust to the Sport is how it sounds. As the name suggests, it’s extreme. It gives you more growl than the Sport, and the aggressive exhaust note on cold start and under full throttle is much more noticeable. The interior sound is much more discernible, which is nice if you prefer hearing your exhaust note while driving.
If you want to enjoy a civilized tone while cruising and bask in the glorious and powerful V8 sound while on full throttle, then you can never go wrong with the Corsa Performance Xtreme Cat-Back Exhaust System.
#4 Flowmaster FX Kit Cat-Back Exhaust System
- Manufacturer: Flowmaster
- Part Number: 717832
- Sound Level: Moderate
- Vehicle Fitment:
- Chrysler 300C (2015-2020)
- Chrysler 300C Platinum (2015-2017)
Don’t you think that Chrysler 300C exhaust systems are a bit expensive? That’s because they are, and there’s no denying that. It’s a long-term investment that will give you more smiles per gallon, so it’s actually a win-win situation for you and your car. However, if you’re budget-restricted and you just want something to make your car sound a tad bit better, then come check out the Flowmaster FlowFX Kit Exhaust System.
The FlowFX Kit offers you an aggressive exterior sound while being moderately loud on the inside. It comes with 2.5” pipings made of 409 stainless steel, which flows into Flowmaster’s Scavenger Series® X-Pipe, resulting in a high-pitched exhaust note. The x-pipe is then mated to a pair of FlowFX straight-through mufflers to ensure that your car gets more exhaust flow and experiences very minimal backpressure.
Since the Flowmaster FlowFX Kit is made from 409 stainless steel, expect it to be much cheaper than its 304 stainless steel counterpart. This exhaust kit may be cheap, but don’t underestimate it yet! Many enthusiasts love this exhaust system because they don’t cost that much, yet it can still provide a satisfactory exhaust note that you may also love once you hear it.
Note: The Flowmaster FlowFX Kit uses the factory hangars, exit, and bezels for a stealthy look.
#5 Flowmaster American Thunder Cat-Back Exhaust System

- Part Number: 817658
- Sound Level: Aggressive
- Vehicle Fitment:

What’s the point of having a V8 engine if you can’t hear it, right? The Chrysler 300C may be a large luxury sedan, but it’s still a muscle car. It is quite a shame to deny it the chance to scream like a proper V8 like it’s meant to be.

This Chrysler 300C exhaust is a low-cost solution for 2nd-generation Chrysler 300C owners who want to hear what their car sounds like in its final form. Just like the FlowFX Kit, the American Thunder has 409 mandrel-bent stainless steel to assist the gas from flowing out of the engine smoothly.
It also has a dual 2.5” Scavenger Series® X-Pipe for a high-pitch exhaust note. The only difference between American Thunder sports is the Super 44™ Series mufflers, which are responsible for the depth and aggression produced by this exhaust’s sound.
Equipping your car with this exhaust system means that you get to enjoy an aggressive exhaust tone, whether you’re inside or outside of the vehicle. The American Thunder may be cheap, but it will let you hear what a real V8-powered muscle car would sound like.

- Manufacturer: Gibson Performance
- Part Number: 617000
- Sound Level: Aggressive
- Vehicle Fitment:
- Chrysler 300C (2011-2015)
Look, you purchased the Chrysler 300C, a luxury muscle car, for a reason. If that reason involves hearing how good a V8 engine sounds, then you deserve a round of applause for your tastes. However, please do note that the stock exhaust sound is not even close to its fullest potential. Equipping your car with an exhaust system like the Gibson Performance Cat-Back Exhaust System can help you uncover the beast hiding under your car’s hood.
This Chrysler 300C exhaust can give you a deep and powerful exhaust rumble without costing you a limb or two. It’s got 2.5” mandrel-bent stainless steel pipes that provide a seamless pathway for the burnt gas to exit into. These pipes are mated to chambered mufflers responsible for the aggressive and drone-less sound you’ll hear while driving. At the end of this connection lies two 4.0” dual wall slash-cut exhaust tips that look terrific when viewed from the rear.
Once you have the Gibson Performance Exhaust System, you can expect a no BS depth and aggression that you wouldn’t usually hear from a relatively cheap setup. You can experience some increase in horsepower as well as improvement in acceleration. These performance gains are noticeable once you go full throttle. Additionally, enthusiasts who’ve had this exhaust system on their cars reported that it has no drone at all.
Benefits of an Aftermarket Exhaust System
There’s a handful of reasons why you should consider replacing your stock exhaust system with a new one.
Performance Gains. An aftermarket exhaust system can definitely boost your car’s horsepower and torque. Although the numbers aren’t astronomical compared to other modifications like turbochargers or superchargers, you can still gain some significant amount of gains.
Sound Improvement. Sound quality is the prevailing reason why enthusiasts like aftermarket exhaust systems. A lot of manufacturers offer innovative exhaust systems that vary from sound level. Whatever your sound preference is, whether it’s aggressive, moderate, or quiet/touring, you’re usually spoiled for choice.
Improved Fuel Economy. It may not be noticeable, but equipping your car with an aftermarket exhaust system can affect how much fuel your engine consumes while it’s operational. Boosts in fuel economy are more noticeable on full exhaust replacements than the typical cat-back/axle-back replacement.
