Key Features of Quit Performance Challenger Exhaust Systems

Quit Performance has designed its exhaust systems with a focus on blending aggressive sound, reliable construction, and performance gains. Each system undergoes rigorous testing to ensure it meets the demands of high-performance driving. Below are the standout features that set these systems apart from stock or aftermarket alternatives.

  • Crisp Sound Profile: The exhaust systems are engineered to produce a deep, resonant tone that commands attention during acceleration while remaining refined at cruising speeds. This balance is achieved through precision-tuned mufflers and mandrel-bent tubing.
  • High-Grade Stainless Steel Construction: Made from T304 stainless steel, these systems resist corrosion, cracking, and heat fatigue even under extreme conditions. The material choice ensures the exhaust retains its appearance and structural integrity for years.
  • Performance Gains: By reducing backpressure and optimizing exhaust flow, the system can yield increases of 10–15 horsepower and 8–12 lb-ft of torque on stock Challenger engines. These gains translate into quicker throttle response and stronger mid-range pull.
  • Direct Fit Design: Each system is CAD-designed to fit specific Dodge Challenger model years (2015–2023) and engine configurations (5.7L HEMI, 6.4L HEMI, 6.2L Supercharged). No cutting, welding, or modifications are required for a truly bolt-on installation.
  • Comprehensive Hardware Kit: All necessary clamps, brackets, and gaskets are included, along with detailed instructions. The kit eliminates trips to the hardware store and reduces installation time to roughly 2–3 hours for most DIYers.

Benefits of Upgrading to Quit Performance Exhaust Systems

Upgrading your Challenger's exhaust system is one of the most effective ways to unlock additional performance and personalize the driving experience. Quit Performance systems deliver a range of benefits that go beyond simple sound improvement.

Enhanced Engine Efficiency and Output

A well-designed aftermarket exhaust system reduces backpressure, allowing the engine to expel exhaust gases more efficiently. This improved flow enables the engine to breathe better, particularly at higher RPMs where the factory exhaust can become restrictive. The result is a measurable increase in horsepower and torque, especially when paired with a cold-air intake or a performance tune. Additionally, the reduced restriction can lead to modest fuel economy gains during highway cruising, as the engine does not have to work as hard to push out spent gases.

Superior Sound Quality and Driver Feedback

The acoustic character of an exhaust system profoundly affects the connection between driver and machine. Quit Performance exhausts produce a deep, throaty growl under hard acceleration that evokes the classic muscle car heritage, yet they remain quiet enough for neighborhood-friendly cruising. At idle, the note is deep and authoritative without being obnoxious. This deliberate tuning ensures that the exhaust enhances the driving experience without causing driver fatigue on long trips.

Weight Reduction and Heat Management

Factory exhaust systems often use heavy, restrictive components. Quit Performance systems are typically 15–20 pounds lighter than stock, reducing overall vehicle weight and improving chassis balance. Furthermore, the mandrel-bent tubing and polished surfaces help dissipate heat more effectively, lowering underbody temperatures and protecting nearby components.

Materials and Durability: Built to Last

Durability is a critical consideration when investing in an exhaust system, especially for vehicles exposed to road salt, moisture, or high heat. Quit Performance constructs its systems from T304 stainless steel, a premium alloy that contains higher levels of chromium and nickel compared to the more common T409 stainless steel. This composition offers superior resistance to rust, pitting, and discoloration. The use of CNC mandrel bending ensures consistent wall thickness and smooth interior surfaces, preventing turbulence and hotspots that could lead to cracking. All welds are TIG-welded and hand-finished for strength and appearance. Combined with heavy-duty hangers and stainless steel clamps, the system is designed to outlast the vehicle itself under normal driving conditions.

Installation Process: A Straightforward Upgrade

Installing a Quit Performance Challenger Exhaust System is a rewarding DIY project that requires only basic automotive tools and a jack or lift. The system is engineered for a direct bolt-on fit with no cutting or welding necessary. Here is an expanded overview of the typical installation steps:

  • Prepare the vehicle: Park on a level surface, engage the parking brake, and allow the exhaust to cool completely. Use jack stands to safely lift the rear of the vehicle.
  • Remove the factory exhaust: Loosen the clamps at the catalytic converter outlet, remove the hangers from the rubber isolators, and carefully lower the stock exhaust system. Penetrating oil can help loosen rusted bolts.
  • Transfer the oxygen sensors: If your Challenger uses post-cat oxygen sensors, unclip them from the old pipes and install them into the new system. Apply anti-seize compound to the threads.
  • Install the Quit Performance system: Begin at the front of the vehicle, loosely attaching the pipes to the catalytic converters or downpipes. Work your way toward the rear, connecting sections with the supplied clamps (do not fully tighten until all pieces are aligned).
  • Hang the system: Hook the new hangers into the factory rubber isolators. Adjust the positioning so that the tips are centered in the rear bumper cutouts and there is at least 1/2 inch of clearance around all body panels.
  • Torque all connections: Starting from the front, tighten all clamps to the manufacturer's specified torque. Double-check that no pipes contact the chassis, driveshaft, or suspension components.
  • Leak test: Start the engine and listen for any exhaust leaks at the joints. A faint puff of smoke or a change in tone can indicate a loose clamp. Shut off the engine and re-tighten as needed.
  • Final check: Lower the vehicle and test drive at varying speeds to confirm that no rattles or vibrations occur. Re-check all clamps after the first heat cycle.

Customer Testimonials: Real Experiences from Challenger Owners

Thousands of Challenger owners have already upgraded to Quit Performance systems. Their feedback provides valuable insight into the real-world performance and quality of these exhausts. Below are a few representative testimonials:

  • Kevin S. (2021 R/T Scat Pack): "I was looking for an exhaust that made my 392 HEMI sound aggressive without droning on the highway.

  • Maria L. (2019 GT AWD): "The build quality is incredible. The stainless steel looks beautiful, and the fitment was perfect. I noticed an immediate improvement in throttle response, and the sound is exactly what I wanted—loud enough to be exciting, but not so loud that I annoy my neighbors."
  • David R. (2016 SRT Hellcat): "On a supercharged car, heat management is critical. This system runs noticeably cooler under the car compared to the stock setup, and the weight savings are a bonus. The sound is simply addictive—it turns heads everywhere I go."
  • Amanda T. (2018 5.7L R/T): "I was nervous about installing an exhaust myself, but the instructions and included hardware made it foolproof. The sound is incredible—crisp and aggressive without being obnoxious. I also feel a real seat-of-the-pants power increase."

Comparison with Factory and Aftermarket Alternatives

When evaluating an exhaust upgrade, it is helpful to understand how Quit Performance stacks up against the factory system and other popular aftermarket options. The factory exhaust is designed for cost efficiency, noise compliance, and reasonable durability—resulting in a system that is heavy, restrictive, and muted in tone. Many mid-range aftermarket systems use T409 stainless steel, which offers adequate rust resistance but is more prone to discoloration and eventual pitting in harsh climates. In contrast, Quit Performance's use of T304 stainless steel provides superior corrosion resistance and a longer lifespan. Additionally, while some budget systems require welding or cutting for proper fitment, Quit Performance's direct-fit design saves time and eliminates guesswork. The result is a system that competes with premium brands like Borla or Corsa at a more accessible price point, delivering comparable sound quality and construction.

Care and Maintenance Tips

To keep your Quit Performance exhaust system looking and performing its best, follow these simple guidelines:

  • Clean the tips regularly using a non-abrasive metal polish to remove brake dust and road grime.
  • Inspect all clamps and hangers every 6 months for signs of loosening due to thermal cycling.
  • Avoid pressure washers directed at the mufflers, as high-pressure water can force moisture into insulation materials.
  • If you drive in winter salt conditions, consider an undercarriage wash every few weeks to prevent salt buildup on the stainless steel.
  • Retorque all clamp bolts after the first 500 miles as the gaskets and materials settle.

Frequently Asked Questions

Will this exhaust void my factory warranty?

No aftermarket exhaust system can automatically void a manufacturer's warranty under the Magnuson-Moss Warranty Act. However, if an exhaust modification directly causes a failure (e.g., removing a catalytic converter), that specific repair may not be covered. Quit Performance systems maintain all emissions controls and are designed to be fully reversible.

Does the system affect emissions compliance?

Quit Performance exhausts are designed as cat-back systems, meaning they replace the exhaust from the catalytic converters back. This configuration does not alter emissions output and is legal in all 50 states for street use. Systems that include high-flow catalytic converters must be verified for local emissions laws.

Can I install this system with aftermarket headers or a supercharger?

Yes, the system is designed to mate to the factory header/front pipe connections. If you have aftermarket headers that reposition the flanges, you may need to make minor modifications or use adapters. For supercharged applications, the increased flow capacity is beneficial and fully compatible.
