How We Picked These Exhausts
You want a Challenger V6 exhaust that fits correctly, sounds better than stock, and holds up over time. We focused on fitment for the 3.6L V6 Challenger, sound character, daily drivability, cabin drone, construction material, installation needs, tip and valance details, and owner feedback themes.
The S-Type system is aimed at drivers who want a deeper and more refined tone. The ATAK system is aimed at drivers who want a more aggressive sound. Both still require fitment checks before purchase because exhaust compatibility can depend on model year, trim, transmission, drivetrain, and rear valance setup.
Fitment Note Before You Buy
Do not order only by product name. Check the Amazon fitment tool, your Challenger year, SXT or GT trim, automatic transmission details, rear valance style, and whether the kit requires factory tips or separate tips. If your car has prior exhaust work, aftermarket rear parts, or rusted factory hardware, installation may take longer.
Borla S-Type Cat-Back 140649
If you want a bolt-on-style upgrade that gives your V6 Challenger a deeper voice without chasing maximum volume, the BORLA 140649 S-Type is the safer first choice. It is built for drivers who want a more mature muscle-car tone at idle, a stronger growl when they press the throttle, and a calmer sound profile during normal cruising.
This is the better fit if your Challenger is a daily driver, commuter car, or weekend cruiser. The tone is still more exciting than stock, but it is less extreme than the ATAK option. That balance matters if you care about phone calls, passengers, long drives, and lower cabin fatigue.
The main things to check are tip setup, rear valance compatibility, and installation access. Some factory exhaust removals can be stubborn, especially on older cars with rusted hardware, so a lift or professional install can save time.

What People Say
Buyer feedback commonly points to a deeper idle, a stronger sound when accelerating, and better daily manners than more extreme exhaust setups. Many owners like that it can stay controlled during normal driving but still sound more exciting when pushed.
Overall Sentiment: Positive
🗣️ Thomas B
Out of all the exhaust systems I have listened to this one is by far the best sounding for the 3.6 V6. Nice deep idle and when you floor it, it screams and sometimes pops when up-shifting.
🗣️ root
By far the best tone I’ve heard. Loud when you get on it but sweet when not on the throttle, absolutely no drone, fits like a glove and super easy to install; quality materials and finish.
Durability
The S-Type system uses T-304 stainless steel and welded construction, which are strong signs for long-term corrosion resistance and durability under normal road use. Clean it with mild products and inspect clamps and joints after installation.
Brand Trust
BORLA is a well-known aftermarket exhaust brand, and this system’s buyer feedback is strongest around tone, fit, and build quality. Still, fitment should be verified before ordering because even a trusted brand can have vehicle-specific compatibility limits.
Who Should Buy This
- Challenger V6 owners who want a deeper sound without the most aggressive volume
- Daily drivers who care about lower cabin fatigue
- Buyers who value stainless construction and a cleaner factory-style fit
- Drivers who want a refined exhaust note instead of a raw race-style bark
Who Should Avoid This
- Drivers who want the loudest BORLA option in this comparison
- Buyers who do not want to verify tip and valance compatibility
- Owners who need a guaranteed plug-and-play install on a modified rear valance
Key Benefits
- Deep, refined idle with stronger sound under throttle
- More daily-friendly than the ATAK for many drivers
- T-304 stainless construction for better long-term durability
- Factory-style hanger alignment when fitment is correct
Borla ATAK Cat-Back 140650
If you want your V6 Challenger to sound sharper and more aggressive, the BORLA ATAK 140650 is the stronger pick. It is designed for drivers who want more growl under throttle, a more dramatic cold-start feel, and a sound that makes the car feel less tame.
Compared with the S-Type, the ATAK is more about excitement than subtlety. It can still be usable for daily driving, but the sound character is more forward, especially when accelerating hard or shifting near the top of the rev range. If you often drive long highway miles with passengers, think carefully before choosing the louder option.
Like the S-Type, confirm tip requirements, valance fit, and exact vehicle compatibility before buying. Installation is usually easier with proper lift access, and it is smart to re-check clamps and hardware after the first few heat cycles.
Pros and Cons

What People Say
Owners often describe the ATAK as the option that makes the V6 feel more awake. Common feedback includes a deeper rumble, louder acceleration sound, and more noticeable pops or crackles during spirited driving.
Overall Sentiment: Positive
🗣️ FLIGHT 2324
I was dissatisfied after initially installing it on my v6 Challenger, it sounded too tame and quiet. All the exhaust needed was wear, tear and time to break in. It seems to sound more and more aggressive the more miles I put on the Borla Atak. Quiet when you want it, but aggressive when you step on it.
🗣️ Tommy
I installed on my 2018 challenger GT. It really wakes up the car and has a nice deep rumble. Especially at idle. From first to second and second to third gear it makes the exhaust really pop when you shift(at redline). Install took me about 2 hours using jacks and jack stands, impact wrench and hand tools. 10/10 recommend.
Durability
The ATAK uses T-304 stainless steel and welded construction, which is useful if you want an exhaust that can handle regular road use and resist corrosion better than cheaper materials. As with any exhaust, clamp checks and occasional cleaning help preserve fit and finish.
Brand Trust
BORLA has a strong name in aftermarket exhausts, and the ATAK line is known for a louder, more assertive sound profile. The key is choosing it for the right reason: sound character first, not quiet cruising.
Who Should Buy This
- Challenger V6 owners who want a louder and more aggressive cat-back
- Drivers who enjoy a sharper exhaust note under throttle
- Weekend drivers who want more presence without changing the whole car
- Buyers who prefer excitement over subtle sound tuning
Who Should Avoid This
- Drivers who want the calmest highway setup
- Owners who are sensitive to cabin noise
- Buyers who do not want to verify factory tips, valance setup, and exact fitment
Key Benefits
- More aggressive ATAK sound for stronger road presence
- Deeper idle and sharper tone under load
- T-304 stainless construction for long-term durability
- Factory-style hanger fitment when matched to the correct vehicle
- Sound character may open up after a break-in period

FAQ
How Do The BORLA S-Type And ATAK Differ In Sound?
The BORLA S-Type 140649 is the more balanced option. It is better if you want a deeper sound than stock but still want a calmer daily drive. The BORLA ATAK 140650 is the more aggressive option. It is better if you want louder acceleration sound, sharper character, and more exhaust presence.
Will A Cat-Back Exhaust Require Tuning?
A cat-back exhaust usually does not require ECU tuning just to run, because it installs behind the catalytic converters. Tuning may be used with other performance upgrades, but it is not normally required for basic cat-back installation. If your car has other modifications or warning lights after installation, have the setup inspected by a qualified shop.
Can A Cat-Back Exhaust Affect Warranty Or Emissions?
A cat-back exhaust should not automatically void your whole vehicle warranty, but a dealer may question a claim if they believe the aftermarket part caused the issue. Keep receipts and installation records. Do not remove catalytic converters unless you have confirmed it is legal where you live, and check local emissions rules before modifying your exhaust.
Do These BORLA Kits Include Exhaust Tips?
Some listings and configurations are designed around factory-valance or no-tip setups, so do not assume new tips are included. Check the product listing, your factory rear valance, and your existing tips before ordering.
Is The ATAK Too Loud For Daily Driving?
It depends on your tolerance for sound. Many drivers enjoy it daily, but the ATAK is the louder and more aggressive system in this comparison. If you carry passengers often, take long highway trips, or want a calmer cabin, the S-Type is the safer choice.
What Installation Tips Matter Most?
Use safe lift points, support the exhaust during removal, apply anti-seize where appropriate, tighten clamps evenly, and re-check hardware after a short break-in period. If the factory exhaust is rusty, a shop can save time and reduce fitment problems.
Final Recommendation
Pick the BORLA 140649 S-Type if you want the best balance of sound, comfort, and daily usability for a compatible Challenger V6. It gives the car more character without pushing volume as hard as the ATAK.
Pick the BORLA 140650 ATAK if you want the more aggressive sound and do not mind a stronger exhaust presence. It is the better choice for drivers who want their V6 Challenger to feel more dramatic when they press the throttle.
In both cases, confirm fitment before you buy, check the tip and valance setup, and plan for a safe installation. Exhaust sound is personal, so choose the system that matches how you actually drive.
