A Cadillac CTS deserves an exhaust note that matches its aggressive styling without causing drone on the highway. Finding the best exhaust for Cadillac CTS can feel overwelming with so many brands and options out there. We break down the top picks so you can choose the right system for your ride.
Your CTS is a performance sedan, not a luxury barge. The right exhaust wakes up the engine, drops weight, and adds a few horsepower. But you also want to avoid that annoying interior hum at cruising speeds. Let’s get straight to the best choices.
Best Exhaust For Cadillac Cts
We tested and researched the top systems for the CTS, covering V6 and V8 models. Each pick focuses on sound, power gains, build quality, and drone control. Here are our top recommendations.
1. Corsa Performance Exhaust
Corsa is the gold standard for no-drone exhausts. Their patented RSC technology cancels out low-frequency sound inside the cabin. You get a loud, aggressive bark outside but a quiet, comfortable ride inside.
- Best for: Eliminating drone completely
- Sound: Deep, aggressive, with no rasp
- Material: 304 stainless steel, mandrel-bent
- Fitment: Direct bolt-on for CTS-V and CTS 3.6L
- Price: Premium, around $1,200–$1,800
If you drive long distances on the highway, Corsa is your best bet. The sound is clean at idle and screams at full throttle. No annoying buzzing at 70 mph.
2. Borla Exhaust System
Borla offers two main lines: the S-Type and the ATAK. The S-Type is more refined, while the ATAK is louder and more race-oriented. Both are built from T-304 stainless steel and come with a million-mile warranty.
- Best for: Aggressive sound with quality construction
- Sound: Deep, with a slight crackle on decel
- Material: T-304 stainless, mandrel-bent
- Fitment: Cat-back systems for most CTS years
- Price: Mid-range, around $900–$1,500
Borla systems tend to have a bit more drone than Corsa, especially the ATAK. But for weekend driving or track days, the sound is incredible. The S-Type is a good compromise for daily driving.
3. MagnaFlow Exhaust
MagnaFlow uses large, free-flowing mufflers and straight-through design. Their systems are known for a deep, muscle-car tone. They also use 100% stainless steel and offer a lifetime warranty.
- Best for: Deep, rumbling tone on a budget
- Sound: Low, throaty, with some interior resonance
- Material: 304 stainless, mandrel-bent
- Fitment: Direct fit for CTS 3.6L and CTS-V
- Price: Affordable, around $600–$1,000
MagnaFlow is louder inside than Corsa. But if you want that classic V8 rumble without spending a fortune, this is a solid pick. The drone is noticeable but not unbearable.
4. AWE Tuning Exhaust
AWE offers two versions: the Touring Edition (quieter) and the Track Edition (louder). Both use drone-canceling 180-degree technology. The fitment is excellent, and the sound is refined.
- Best for: Balance between sound and comfort
- Sound: Smooth, with no rasp, deep tone
- Material: 304 stainless, CNC mandrel-bent
- Fitment: Direct bolt-on for CTS-V and 3.6L
- Price: Mid-range, around $1,000–$1,400
The Touring Edition is almost as quiet as Corsa inside but costs less. The Track Edition is for those who want maximum volume. Both are well-engineered and easy to install.
5. Gibson Performance Exhaust
Gibson focuses on muscle car and truck exhausts, but their CTS systems are solid. They use a dual-wall tip design and a free-flowing muffler. The sound is aggressive but not overbearing.
- Best for: Budget-friendly upgrade
- Sound: Deep, with a slight drone at highway speeds
- Material: Aluminized steel or stainless options
- Fitment: Cat-back for 3.6L models
- Price: Budget, around $400–$700
Gibson is not as refined as Corsa or Borla. But if you want a louder exhaust without spending a lot, it works. The aluminized steel version may rust over time, so go with stainless if you can.
How To Choose The Right Exhaust
Picking the best exhaust for your CTS depends on your priorities. Here is a simple step-by-step guide.
- Decide on sound level: Do you want loud, moderate, or quiet?
- Check for drone: If you drive highway often, choose Corsa or AWE Touring.
- Consider material: 304 stainless steel lasts longer than aluminized.
- Look at warranty: Borla and MagnaFlow offer lifetime coverage.
- Check fitment: Make sure the system matches your engine (V6 or V8).
Also, think about installation. Most cat-back systems bolt on in a few hours. If you are not handy, budget $100–$200 for a shop install.
V6 Vs V8 Exhaust Differences
The CTS comes with a 3.6L V6 or a 6.2L V8 (CTS-V). The exhaust needs are different.
- V6: Sounds best with a system that adds bass and removes rasp. Corsa and Borla work well.
- V8: Needs a system that handles deep, low-frequency sound. MagnaFlow and AWE are great.
Do not use a V8 exhaust on a V6. The pipe diameters and muffler tuning are different. Always buy the system made for your engine.
Installation Tips
Installing a cat-back exhaust is a weekend project. Here are some tips.
- Use penetrating oil on bolts a day before.
- Lift the car safely on jack stands.
- Remove the old system in sections.
- Test fit all parts before tightening.
- Check for leaks after startup.
If you hit a snag, watch a YouTube video for your specific model. Most systems come with instructions.

No, but if a dealer blames the exhaust for a problem, they may deny a claim. Stick with cat-back systems, which do not affect emissions.
Does A Cat-back Exhaust Add Horsepower?
Yes, but only 5–15 hp on a stock CTS. The main benefit is sound and weight reduction.
Can I Install It Myself?
Yes, if you have basic tools and jack stands. Most systems bolt on in 2–4 hours.
Which Exhaust Is Loudest?
Borla ATAK and AWE Track Edition are the loudest. Corsa is loud outside but quiet inside.
What About Drone?
Corsa and AWE Touring have the least drone. MagnaFlow and Gibson have more.
Final Thoughts
Choosing the best exhaust for Cadillac CTS comes down to your driving style. If you want zero drone, go Corsa. If you want aggressive sound with quality, pick Borla. For a budget option, MagnaFlow works well. AWE offers a great balance. Gibson is for tight budgets.
Listen to clips, read reviews, and pick the one that fits your needs. Your CTS will sound amazing, and you will enjoy every drive.
Remember to check fitment for your specific year and engine. Most systems are direct bolt-on, but some may require minor adjustments. Enjoy the new sound.
