How We Picked These Exhausts

You want a system that fits your car, matches your sound preferences, and gives reliable performance without creating unnecessary headaches. We prioritized fitment for Dodge Challenger R/T 5.7L applications, sound character, material quality, bolt-on installation, drone control, brand reputation, owner feedback, and value.

We also looked for clear use cases. Some drivers want a refined daily-driver tone with stainless durability. Others want the loudest possible muscle-car sound. The right pick depends on your model year, engine, transmission, MDS or non-MDS setup, budget, and tolerance for cabin noise.

Before You Buy: Fitment Checklist

  • Confirm your model year. A 2009–2014 exhaust will not automatically fit a 2015–2023 car.
  • Confirm your engine. This guide is focused on Challenger R/T 5.7L Hemi fitment, not V6, Hellcat, or Scat Pack 6.4L systems.
  • Check MDS or cylinder deactivation compatibility. Some systems are listed for non-MDS cars, so verify before ordering.
  • Check transmission notes. Manual and automatic cars can have different fitment details depending on the part number.
  • Verify with your VIN or Amazon fitment tool. Exhaust returns can be costly because these systems are large and heavy.
  • Keep your factory exhaust parts. This helps if you need a warranty discussion, inspection, resale, or reversal later.

Best overall pick for many 2015–2023 Dodge Challenger R/T 5.7L owners who want stainless construction and a stronger Hemi tone.

Best Overall

Check Price on Amazon

You’re looking at a straight-up performance upgrade for a 2015–2023 Dodge Challenger R/T 5.7L V8, especially if you want a premium cat-back that feels like it belongs on the car. The Borla 140628 Cat-Back is described as T-304 stainless, all-welded, made in the USA, and designed as a bolt-on system.

What you get is a deep, aggressive Borla sound that carries outside but stays more civilized inside than a raw straight-pipe-style setup. It gives your Challenger more presence at a stoplight, on a back road, or under an overpass, yet it is still practical enough for daily driving when installed correctly.

Why You’ll Like It

This is the easiest recommendation if you want a premium-feeling exhaust with a recognizable Borla tone, stainless durability, and a fitment range that covers many newer R/T model years.

What People Say

You’ll see owners praise the aggressive, non-raspy sound and note minimal cabin drone, plus consistent build quality.

🗣️ Amazon Customer

Describes the system as one of the strongest-sounding exhaust upgrades they have heard, with an aggressive growl that clearly announces the car.

Who Should Buy This

Buy this if you have a compatible 2015–2023 Challenger R/T 5.7L and want the safest premium pick in this group for sound, build quality, and daily usability.

Who Should Avoid This

Skip it if your car has a different engine, different trim, or a fitment note that conflicts with MDS, transmission, or year range. Also skip it if you want the cheapest possible exhaust instead of a premium stainless system.

Versatility

Works well as a daily driver upgrade because it keeps in-cabin noise manageable, but also opens up into a throatier, attention-getting tone for meets, overpass pulls, or weekend runs.

Problem Solving

Fixes the bland factory tone and gives your Challenger a proper Hemi soundtrack while addressing common complaints like interior drone and weak factory presence.

Key Benefits

  • Classic Borla outside roar with low interior drone

MBRP 15-16 Challenger RT Cat-Back

MBRP 15-16 Dodge Challenger RT 5.7L Aluminized Steel 3in Dual Rear Cat-back Quad Tips – Street

You’re looking at a direct-fit cat-back built for 2015–2016 Dodge Challenger R/T 5.7L models. It uses aluminized alloy steel with 3 in. piping, dual rear routing, and quad tips, and it is designed as a bolt-on system.

This is the value-minded pick if your main goal is to improve sound and rear-end appearance without moving into a premium stainless price tier. The quad-tip layout gives the back of the car a more purposeful look, while the 3 in. piping helps the system feel like a true cat-back upgrade instead of a simple cosmetic change.

If you want a solid, no-nonsense upgrade that improves flow, looks more aggressive, and does not require major fabrication, this is worth considering for the correct 2015–2016 R/T fitment.

If you want your 2009–2014 Challenger R/T to sound alive without turning every drive into a full-time drone chamber, this Borla ATAK system is worth a look.

Who Should Avoid This

Skip it if you want a subtle daily-driver tone, if your car is outside the listed fitment range, or if your neighborhood, commute, or local noise rules make an aggressive exhaust a bad idea.

Versatility

Good for drivers who want a stronger sound for spirited runs, meets, and weekend drives, while still keeping a more controlled cruise than a poorly tuned loud exhaust.

FAQ

How Do I Choose The Right Exhaust For My Dodge Challenger R/T?

Start by confirming your car’s year, engine, transmission, and MDS or cylinder deactivation setup. A system for a 2009–2014 Challenger R/T 5.7L may not fit a 2015–2023 car, and a system for a 6.4L Scat Pack or SRT model should not be treated as a guaranteed fit for a standard R/T 5.7L.

After fitment, decide what matters most: sound, material, budget, or cabin comfort. Stainless steel usually gives better long-term corrosion resistance, while aluminized steel can be more budget-friendly. BORLA systems tend to focus on a refined performance tone, while MBRP is a practical value option for the right 2015–2016 R/T fitment. Always verify the product’s compatibility notes or use your VIN before buying.

Will Installing An Aftermarket Cat-Back Void My Warranty Or Cause Emissions Problems?

A cat-back exhaust usually keeps the factory catalytic converters in place, but warranty and inspection outcomes can still vary by dealer, local rules, and how the system is installed. Keep your OEM parts, receipts, and installation records in case you need them later.

If you live in an area with strict emissions or noise rules, check local requirements before ordering. Avoid any setup that removes or alters emissions equipment unless it is clearly legal for your location and intended use.

How Loud Will These Exhausts Be And Will I Get Annoying Drone On Long Drives?

Expect a range of character. The BORLA 140628 is the strongest all-around pick for many newer R/T owners because it adds a deep tone while staying more livable inside. The BORLA 140707 is a classic stainless choice for 2009–2014 R/T drivers, while the BORLA 140708 ATAK is the aggressive option. The MBRP system gives 2015–2016 R/T owners a more value-focused, street-oriented upgrade.

Drone depends on muffler tuning, cabin resonance, installation quality, hanger alignment, and exhaust leaks. If drone is a deal-breaker, avoid choosing only by loudness. Listen to long-cruise clips when available, check owner feedback for your exact model year, and have the installer check clamps, gaskets, and hangers after the first heat cycles.

Can I Use A 2009–2014 Exhaust On A 2015–2023 Challenger R/T?

No, you should not assume interchangeability. Challenger exhaust routing, hangers, tips, rear bumper layout, and drivetrain details can vary by generation and trim. Match the part number to your exact model year, engine, and transmission before ordering.

Is Stainless Steel Worth It Over Aluminized Steel?

Stainless steel is usually the better long-term choice if you keep your car for years, drive in wet weather, or live where road salt is common. Aluminized steel can still make sense if your budget is tighter, your car sees fair-weather use, or you are focused on value rather than maximum corrosion resistance.

Drivers Top Picks

When you’re choosing between the Borla 140628, Borla 140707, MBRP 15-16 Challenger RT cat-back, and Borla 140708 ATAK, start with fitment first. Then compare sound character, material, drone control, installation style, and how much aggression you want from your 5.7L Hemi.

Drivers Top Picks Chart

Wrapping Up

You can make your Challenger feel more exciting by choosing the right exhaust for how you drive. If you own a compatible 2015–2023 R/T 5.7L and want the signature Borla clarity with a premium stainless build, the BORLA 140628 is the top pick.

If you want a value-focused option for a 2015–2016 R/T, the MBRP system gives you a more aggressive look and full cat-back layout. If you drive a 2009–2014 R/T, the BORLA 140707 is the cleaner classic choice, while the BORLA 140708 ATAK is for drivers who want the boldest sound.

Fitment matters more than hype. Confirm your year, engine, transmission, and MDS notes before ordering, and choose the tone that fits your commute, neighborhood, and driving style.
