A strong Hellcat exhaust choice delivers compatible cat-back fitment, durable stainless construction, and a sound level that matches how you drive, whether you use a Challenger SRT Hellcat daily or own a Durango SRT Hellcat. The supplied list includes two Borla systems identified for the Challenger SRT Hellcat and one Borla ATAK system developed for the Durango SRT Hellcat. Several other listings target different vehicles, including a 5.7L Dodge Durango, Challenger SRT 392, RAM 1500, Subaru, or unspecified applications, so they should not be treated as direct Hellcat recommendations without confirming fitment.
Focus first on vehicle configuration, then compare valve provisions, pipe diameter, tips, installation method, material, and expected cabin character.
For a Challenger SRT Hellcat, the Borla 140646 options are the clearest matches: both use T-304 stainless steel, bolt-on installation, welded construction, and a no-drone guarantee, while the listings differ in valve and tip details. For a Durango SRT Hellcat, Borla 140888 is the relevant listing and adds a merge X-pipe with an ATAK sound focus. Confirm the exact vehicle before buying, because the remaining products list other applications or lack clear Hellcat compatibility.

What Buyers Often Overlook
Fitment and valve configuration matter more than appearance
The most important distinction is whether the system is identified for the specific Hellcat vehicle, because the supplied products span multiple platforms. Borla 140646 is listed for the Challenger SRT Hellcat and uses a dual split rear exit; one listing says it does not include tips and requires the factory bezel or valance, while the other specifies valve simulators, a single 2.75-inch exit on each side, and reuse of original-equipment tips. Borla 140888 is described for the Durango SRT Hellcat and is tuned for the supercharged 6.2L HEMI.
By contrast, the AWE Touring listing targets a 5.7L Dodge Durango, Vicrez targets a Challenger SRT 392, and the AWE 0FG listing targets a RAM Those applications make them poor direct matches unless a seller confirms compatibility.
Check body style, drivetrain, transmission, valve hardware, tip reuse, and rear-valance clearance before ordering.
The Key Product Trade-Off
Stainless construction and installation features shape ownership
T-304 stainless steel gives the two Borla Challenger listings a clearly stated material choice, while Borla 140851 also identifies stainless steel but does not identify a Hellcat application. Borla 140646 emphasizes bolt-on installation and all-welded construction, which can simplify installation compared with systems requiring cutting or welding; Vicrez likewise advertises a clamp-on, direct-fit replacement design, but its listed application is not the Hellcat. Flowmaster 817737 lists factory hanger locations, stainless construction, tuned resonators, and an X-pipe, while Flowmaster 817895 lists factory hanger locations, stainless construction, a Super 40 muffler, and included black ceramic-coated quad tips.
These features describe installation and hardware choices, not guaranteed Hellcat fitment. The practical trade-off is straightforward: prioritize verified vehicle compatibility first, then choose bolt-on or clamp-on hardware, tip inclusion, valve provisions, and sound-control features.
Best Exhaust For Hellcat: Buyer's Guide
Fit, Dimensions, and Compatibility
Compare the listed dimensions with the intended counter, cabinet, appliance, storage, or installation space. Confirm model compatibility and connection requirements where they are supplied. A useful feature cannot compensate for a product that does not physically fit or work with the buyer’s existing setup.
Capacity, Output, and Operating Format
Match listed capacity, volume, output, and operating mode to the actual household or work routine. Larger figures can support heavier use, while a smaller format may be easier to place and maintain. Treat daily output, immediate storage, and container capacity as separate specifications when the listing distinguishes them.
Materials, Construction, and Care
Use the listed materials and care instructions to judge cleaning effort, storage conditions, and compatibility with the intended use. Dishwasher, freezer, food-contact, or weather-related claims are included only when supplied for that product. Check whether routine care fits the way the product will be used.
Included Components and Setup Needs
Review the included components before planning installation or first use. Hoses, adapters, lids, paddles, bowls, brushes, controls, and manuals vary by listing. Confirm power, water, assembly, or accessory requirements from the supplied product information rather than assuming that separately pictured parts are included.
Which Should You Choose?
Choose the Borla 140646 listing that matches your Challenger SRT Hellcat configuration if you want T-304 stainless steel, bolt-on installation, welded construction, and a stated no-drone guarantee. Select the version with valve simulators and reuse of original-equipment tips when those details suit your car; select the listing that requires factory bezel or valance compatibility only after confirming your existing rear trim and tip arrangement. For a Durango SRT Hellcat, Borla 140888 is the relevant option in this data and adds a merge X-pipe with ATAK tuning.
Treat the Flowmaster, Vicrez, AWE, and other Borla listings as application-specific alternatives rather than direct recommendations until fitment is verified. The deciding checks are vehicle platform, valve hardware, exit layout, tip requirements, and installation method.
Quick Buying Checklist
- Confirm the complete dimensions against the available space.
- Verify model, accessory, connection, and appliance compatibility.
- Match capacity or output to the expected amount of use.
- Compare materials and care instructions with the maintenance routine.
- Check the included components before planning setup or first use.
- Confirm listed power, water, storage, or installation requirements where applicable.
Frequently Asked Questions
What is a cat-back exhaust system?
A cat-back exhaust system replaces the factory exhaust components from the catalytic converter back to the tailpipe. This typically includes the muffler, pipes, and tips, offering improved sound and performance.
Will a new exhaust affect my Hellcat's warranty?
Modifying the exhaust system can potentially void parts of your vehicle’s warranty, especially if the modification is deemed the cause of a failure. It’s advisable to consult your dealer or warranty documentation.
How does exhaust sound differ between systems?
Exhaust systems vary in sound based on muffler design and pipe diameter. Some offer a deep, aggressive tone (like ATAK), while others provide a more refined, touring sound, impacting the overall driving experience.
Are there specific exhaust systems for Hellcat models?
Yes, many exhaust manufacturers offer systems specifically designed for the Dodge Challenger SRT Hellcat. These are engineered to fit the vehicle’s chassis and exhaust ports for optimal performance and sound.
What is the benefit of stainless steel construction?
Stainless steel construction offers superior durability and corrosion resistance compared to standard steel. This ensures a longer lifespan for the exhaust system, even in harsh driving conditions, and maintains its appearance.
Final Words
Selecting the right exhaust for your Hellcat involves balancing sound preference with performance goals. Systems like Borla’s ATAK offer an aggressive note, while others focus on a more refined tone. Consider your desired driving experience and ensure compatibility with your specific Hellcat model for the best results.
