Charger Scat Pack: What the Corsa Sport Cat-Back Actually Sounds Like, 2015-2023

The Charger Scat Pack is the most-recorded car in our library. Over forty clips, model year 2015 through the end of the 6.4 HEMI Charger's run, on one system: the Corsa Polished Sport cat-back.

That sounds like a limitation. It isn't. Almost every exhaust decision is made off a single video of a single car, and you have no idea whether what you're hearing is representative or whether that particular car had a worn cat, a resonator delete, a tune, or a phone held two feet from the tip. Forty recordings of the same system across nine model years tells you something a single clip can't: what this exhaust reliably does, rather than what it did once.

The system

The Corsa Sport cat-back for the LX/LD platform 6.4 cars is a 2.75" stainless system with twin 4.5" polished Pro-Series tips — the Charger Sport version carries MPN 14995, listed as fitting the 6.4 and 6.2 V8 cars. It's a straight-through design, not chambered.

Sport is the middle of Corsa's three sound levels. Corsa's own descriptions, from their technology page:

  • Touring — "Similar in overall loudness to the stock system with the coveted CORSA tone."
  • Sport — "louder than stock and often referred to as 'how it should have come from the factory'."
  • Xtreme — "The most aggressive option under acceleration while maintaining a drone free at cruise."

That middle description is the honest pitch for this car. The Scat Pack already sounds good from the factory. The Sport doesn't reinvent it; it removes the muffling that makes a big-bore V8 sedan sound apologetic at part throttle.

Why drone is the whole game on this car specifically

A Scat Pack is a heavy, long-wheelbase, four-door car with an eight-speed automatic. It is built to cruise, and it cruises at low RPM.

Run the numbers. Firing frequency for a four-stroke is (RPM × cylinders) ÷ 120:

  • V8 at 1,600 RPM → 107 Hz
  • V8 at 1,800 RPM → 120 Hz
  • V8 at 2,000 RPM → 133 Hz

Every one of those sits in the band where a car cabin amplifies rather than absorbs, and the eight-speed will happily hold you at 1,600–1,800 RPM at 70 mph all day. This is the textbook drone scenario — big V8, tall gearing, large enclosed cabin, long highway trips.

It's also why Corsa's RSC matters more here than it would on a short-geared coupe. Corsa describes Reflective Sound Cancellation as using "specific geometry to reverse 180 degrees out of phase" to remove unwanted low-frequency waves, and applies it across all three sound levels rather than only to the quiet one. The design intent is exactly the 107–133 Hz band the Scat Pack lives in.

Whether it works for you is something you can check rather than take on trust, which is the point of what follows.

Use the clips properly

Pick your model year first. Dodge revised the LX/LD platform over its run, and the pre-facelift 2015 cars don't have identical exhaust hardware to the late ones. Start with the year closest to yours:

Then listen to several clips of the same year. This is the part most people skip and it's the most valuable thing here. Nine recordings of 2021 cars on the same exhaust means you can hear past the recording and to the exhaust. If eight of nine sound one way and one sounds different, you've learned something about the outlier, not about the system.

Then listen to the boring bits. Everyone plays the rev. The rev tells you about tone. Steady cruise and light throttle tell you about your commute. On this car, that's the part that matters.

The two comparisons the library gives you for free

5.7 R/T vs 6.4 Scat Pack, same exhaust

We have a 2018 Charger R/T on the same Corsa Polished Sport system. Same car, same exhaust, smaller engine.

If you're cross-shopping an R/T and a Scat Pack, or you own an R/T and you're wondering whether the Scat Pack clips apply to you, this is the reference point. The exhaust is the constant; the engine is the variable. That's a comparison you'd normally have to guess at.

Sport vs Xtreme, via the Challenger

Here's a quirk of the library worth exploiting. Every Charger clip we hold is the Corsa Sport. Every Challenger clip we hold is the Corsa Xtreme. Same 6.4 engine, same manufacturer, same platform family — different sound level.

So: 2019 Challenger Scat Pack on Corsa Polished Xtreme against any of the Charger Sport clips gives you a reasonable feel for what the step up from Sport to Xtreme costs and buys.

One honest caveat, because it matters: a Challenger is not a Charger. Two doors versus four, different wheelbase, different cabin volume, different body resonance. The engine and the muffler technology are the same, so the tonal difference you hear is largely the muffler — but don't treat it as a controlled experiment. Use it to understand the direction of the change, not the exact magnitude.

Choosing your sound level

Corsa Touring if you want the Corsa tone without a volume increase. Realistically a small audience on a Scat Pack — if you wanted quiet you'd have bought the V6.

Corsa Sport if you want the car to sound like it should have from the factory, and you do real highway miles. This is what over forty of our clips are of, and it's the default recommendation for a Scat Pack that's somebody's actual car.

Corsa Xtreme if you've heard it and you want it. It's a genuine step up in aggression. Corsa still claims drone-free cruise, and RSC is present, but you're removing more packed material and you should listen to the Challenger clips first with the body caveat in mind.

Practical notes before you order

Tips. Twin 4.5" polished Pro-Series is a specific look and a bright one. If your car is blacked out, check whether a black PVD tip version is available for your application before you settle on polished — it's the hardest thing to change your mind about later.

Your year. Confirm fitment against your exact model year rather than "LD Charger." Corsa is explicit that their systems are engineered per vehicle and they don't recognise installations on vehicles outside the stated application.

Install. A cat-back on this car is roughly one to two hours on a lift. It's a reasonable driveway job with proper jack stands, but the flange hardware is the usual risk.
