You drive a Dodge Challenger Scat Pack because you want power, presence, and a sound that matches the 6.4L HEMI. The right exhaust upgrade can make your car feel more alive, but the best choice depends on more than volume. You need the right fitment, the right sound level, and the right balance between aggressive tone and daily-driving comfort.
This guide focuses on exhaust upgrades that fit the Scat Pack buyer intent: full cat-back systems for a complete sound and flow upgrade, plus one budget-friendly mid-muffler delete kit for drivers who mainly want a stronger exhaust note. Before ordering, always confirm your exact model year, engine, transmission, active exhaust valve setup, pipe diameter, and whether the system reuses factory tips.

How We Selected The Best Exhaust Systems
When evaluating exhaust upgrades for your Dodge Challenger Scat Pack, we focused on five practical buying factors: sound profile, drone control, fitment clarity, build quality, and installation type. A great Scat Pack exhaust should deliver a stronger muscle-car tone without making highway drives miserable.
We also separated full cat-back systems from simpler mid-muffler delete kits. A cat-back system is usually the better choice if you want a more complete upgrade. A mid-muffler delete is better for shoppers who mainly want a louder sound at a lower cost, but it may be louder, less refined, and more dependent on local noise rules.
Before You Buy: Fitment Checklist
- Confirm your Challenger model year, trim, and 6.4L engine configuration.
- Check whether your car has active exhaust valves and whether the system supports them.
- Confirm MDS/cylinder deactivation compatibility if your car uses it.
- Check pipe diameter before buying a mid-muffler delete kit.
- Confirm whether the system includes tips or reuses your factory tips.
- Consider local noise rules before choosing an extreme or muffler-delete setup.
- Plan for professional installation if you do not have safe lift access, cutting tools, or exhaust-clamp experience.
BORLA 140641 Cat-Back System
If you want the cleanest overall upgrade for a Challenger Scat Pack, the BORLA 140641 Cat-Back System is the strongest place to start. It is aimed at drivers who want a deeper, more serious exhaust note without turning the car into a tiring highway cruiser.
The key appeal is the full cat-back design. Compared with a small muffler-only change, this gives you a more complete exhaust upgrade while keeping the car looking close to factory because this setup is designed to reuse the stock tips. Borla’s straight-through and multi-core design also focuses on better exhaust flow, though actual power gains can vary by vehicle setup.
This is the best fit if you want a premium upgrade and do not want to gamble on a low-cost sound-only mod.
Who Should Buy This
- You want a complete cat-back exhaust instead of a simple muffler delete.
- You prefer a deep, aggressive Borla-style muscle-car tone.
- You want durable stainless construction and a cleaner OEM-style appearance.
- You are willing to pay more for a better-known exhaust brand.
Who Should Avoid This
- You only want the cheapest way to make your Scat Pack louder.
- You want an extreme-volume setup above all else.
- You have not confirmed your active exhaust valve and model-year fitment.

Corsa 14996 Cat Back Exhaust
The Corsa 14996 Cat Back Exhaust is the pick for drivers who want a more dramatic sound profile but still care about highway comfort. It is built around Corsa’s Reflective Sound Cancellation technology, which is designed to keep the cabin calmer during steady cruising while still letting the exhaust open up when you accelerate.
This is the option to consider if your Scat Pack feels too quiet but you do not want the constant low-frequency hum that can come with some louder exhaust setups. It is also a better fit than a muffler delete if you want a full cat-back layout and a more polished upgrade.
Who Should Buy This
- You want one of the more aggressive-sounding options in this roundup.
- You want a cat-back system instead of a cut-and-clamp muffler delete.
- You care about reducing cabin drone during highway cruising.
- You want stainless steel construction and bolt-on installation.
Who Should Avoid This
- You want a quieter, mild exhaust upgrade.
- Your local noise rules are strict and you often drive early or late in residential areas.
- You have not confirmed exact fitment for your model year and exhaust configuration.
Where It Really Shines
|
Situation |
How It Helps |
|---|---|
|
Daily Commute |
You get a stronger exhaust note while keeping steady-speed cruising more controlled. |
|
Highway Trips |
The RSC-focused design helps reduce the kind of drone that can make long drives tiring. |
|
Car Shows/Meets |
Your Challenger gets a sharper, more aggressive tone when you want it to stand out. |
|
Spirited Driving |
The system lets the HEMI sound more open and responsive when you lean into the throttle. |
Why It Stands Out
- You get a more aggressive exhaust note without choosing a basic muffler delete.
- Corsa’s RSC design is built to reduce unwanted cabin resonance during cruise.
- 304 stainless steel construction adds durability for long-term use.
- The bolt-on layout is more installation-friendly than a custom-fabricated setup.
- It is a strong choice for drivers who want sound drama with better daily usability.

Corsa 14994 Cat Back Exhaust
The Corsa 14994 Cat Back Exhaust is another strong choice if your top concern is getting an aggressive tone without making the cabin unpleasant during steady cruising. Its main selling point is Corsa’s RSC approach, which is designed to separate louder acceleration sound from calmer highway behavior.
This product is best treated as a fitment-specific Corsa option rather than a universal Scat Pack recommendation. If your car matches the supported year and trim configuration, it can be a smart choice. If your car is a later Scat Pack or has a different exhaust-valve setup, confirm fitment on Amazon and with the manufacturer before ordering.
Who Should Buy This
- You want a Corsa cat-back with strong drone-control appeal.
- Your Challenger matches the listed fitment for this part number.
- You want a sporty tone that stays more livable during steady cruising.
Who Should Avoid This
- You own a model year that is not clearly covered by this listing.
- You want the most extreme Corsa sound available in this roundup.
- You are shopping mainly by lowest cost.

Truck Exhaust Kits Round Muffler Replacement
This kit is for drivers who want a louder Scat Pack without paying for a full cat-back system. It is a mid-muffler delete, which means it changes a specific part of the exhaust rather than replacing the full rear exhaust path.
The upside is simple: it can give your HEMI a louder, more direct tone for less money. The trade-off is that it is less refined than a premium cat-back system, may create more cabin resonance, and depends heavily on exact pipe diameter and muffler style. If your car does not have the listed 2.75-inch pipes and round mid mufflers, do not assume it will fit.
Who Should Buy This
- You want a budget-friendly sound upgrade.
- Your Challenger or Charger matches the listed pipe and muffler configuration.
- You are comfortable with a louder, less refined exhaust character.
- You understand this is a mid-muffler delete, not a full cat-back system.
Who Should Avoid This
- You want the most polished daily-driver exhaust tone.
- You frequently drive in areas with strict noise enforcement.
- You do not want to cut or clamp exhaust parts.
- You own a model year or pipe setup that does not clearly match the listing.
When This Kit Shines
|
Situation |
How It Helps |
|---|---|
|
Cruising Around Town |
Your Challenger gets a louder, more noticeable HEMI sound. |
|
Budget Builds |
You can change the sound without buying a full cat-back exhaust. |
|
Quick Sound Projects |
The cut-and-clamp style can be simpler than installing a complete system, but proper tools and safety still matter. |
|
Weekend Cars |
The louder tone may be more enjoyable if your Scat Pack is not your quiet daily commuter. |
What It Does For You
- It gives your HEMI a louder, more aggressive sound.
- It is a lower-cost alternative to a full cat-back system.
- The cut-and-clamp design can be manageable for experienced DIY installers.
- It is best for sound-first buyers who understand the fitment and noise trade-offs.

BORLA 140640 Cat-Back System
The BORLA 140640 Cat-Back System is relevant for Scat Pack shoppers, but it should be approached more carefully than the top BORLA pick. It offers the core Borla appeal: stainless construction, mandrel-bent piping, a straight-through design, and a stronger exhaust note.
The reason it sits lower in this guide is buyer confidence. The source content suggests more mixed feedback than the leading options, especially around possible drone behavior. That does not make it irrelevant, but it does mean you should confirm fitment, sound expectations, and return/warranty terms before choosing it over the stronger BORLA 140641 or Corsa picks.
Who Should Buy This
- You specifically want this Borla part number for your build.
- You have confirmed fitment for your model year and exhaust configuration.
- You prefer Borla’s tone and stainless construction over a budget muffler delete.
Who Should Avoid This
- You want the safest overall recommendation in this roundup.
- You are especially sensitive to cabin drone.
- You have not confirmed whether this is the correct Borla configuration for your car.
Where It Really Shines
|
Situation |
How It Helps |
|---|---|
|
Borla-Focused Builds |
It gives you another Borla cat-back option if this part number matches your exact car. |
|
Sound Upgrades |
The straight-through design is built to create a stronger, more open exhaust note. |
|
Durability-Focused Buyers |
Stainless construction and mandrel-bent piping make it more appealing than many basic sound-only parts. |
|
Careful Shoppers |
If you verify fitment and understand the sound trade-offs, it may still be a workable option. |
Why This System May Be Worth Checking
- It is a true cat-back system, not just a muffler delete.
- It uses stainless materials and mandrel-bent tubing.
- It may suit buyers who want a specific Borla configuration.
- It should be compared carefully against the BORLA 140641 before buying.

FAQ
How Will An Aftermarket Exhaust Change The Sound Of My Scat Pack?
An aftermarket exhaust can make your Scat Pack sound deeper, louder, sharper, or more aggressive depending on the system you choose. A full cat-back system usually gives a more complete and refined change, while a mid-muffler delete tends to create a louder and more direct sound.
If you daily drive your Challenger, pay close attention to drone control. A louder exhaust may sound great during acceleration, but steady highway resonance can become tiring if the system is not well matched to your car.
Do These Exhaust Systems Actually Add Horsepower?
They can improve exhaust flow, and some drivers may feel better throttle response or stronger sound feedback. However, actual horsepower gains depend on the exact vehicle, tune, supporting modifications, and testing method. Treat performance claims as a possible benefit, not a guaranteed result.
Is A Cat-Back System Better Than A Mid-Muffler Delete?
A cat-back system is usually better if you want a more complete and polished upgrade. It replaces more of the exhaust path and is often designed with tone, flow, and drone behavior in mind.
A mid-muffler delete is better if your main goal is a louder sound at a lower cost. It can be fun, but it may be less refined and may not be ideal for long highway trips or strict noise areas.
What Should I Check Before Ordering A Challenger Scat Pack Exhaust?
Check your model year, engine, transmission, active exhaust valve setup, MDS/cylinder deactivation configuration, pipe diameter, and whether the system includes or reuses tips. Never rely only on a product title. Use the Amazon fitment tool, read the listing details, and confirm with the manufacturer when possible.
Will A Louder Exhaust Affect Daily Driving?
Yes, it can. A louder exhaust can make every drive feel more exciting, but it can also create cold-start noise, cabin drone, and passenger complaints. If you commute often, choose a system known for better cruise comfort instead of picking the loudest option available.
Your Top Picks
When choosing your top pick, start with how you actually drive. If your Scat Pack is a daily driver, prioritize a cat-back system with better drone control. If it is a weekend car, a more aggressive option may be worth it. If you only want a budget-friendly sound change, the mid-muffler delete kit can work, but only if the fitment matches your exact car.
For most shoppers, the BORLA 140641 is the best overall choice. For a more aggressive Corsa sound with drone-control technology, the Corsa 14996 is the better pick. For a lower-cost sound-first upgrade, consider the Truck Exhaust Kits Round Muffler Replacement after confirming pipe size and muffler style.

Wrapping Up
Selecting the right exhaust system for your Dodge Challenger Scat Pack comes down to sound, fitment, comfort, and budget. A premium cat-back system is the better choice if you want a more complete upgrade with a refined tone. A mid-muffler delete is better if you want a louder sound for less money and accept the trade-offs.
Before buying, confirm your exact fitment and think honestly about how often you drive the car. The best Scat Pack exhaust is not always the loudest one. It is the one that gives you the tone you want without making the car harder to enjoy.
