The Nissan 370Z’s VQ37VHR engine responds exceptionally well to a free-flowing exhaust, but drone can be a major issue. Finding the best exhaust for Nissan 370Z means balancing power gains with daily drivability. You want that iconic V6 roar without the headache of constant cabin resonance.
We tested dozens of systems on the dyno and on the road. This guide breaks down the top picks based on sound, performance, fitment, and budget. Whether you want a track weapon or a weekend cruiser, there’s an option here for you.
Best Exhaust For Nissan 370Z
The aftermarket is flooded with choices. Some systems scream, others sing. A few drone like crazy. We focused on systems that deliver real horsepower gains while keeping the interior tolerable for long drives.
Top 5 Exhaust Systems Ranked
These are the systems that consistently get praised by owners and tuners. Each one has a distinct personality.
- Fast Intentions TDX: Best overall for power and sound control
- Stillen Cat-Back: Great value with proven gains
- ARK Performance Grip: Deep tone with minimal drone
- Injen Evolution: Loud and aggressive for track use
- HKS Hi-Power: Classic JDM sound with quality build
Fast Intentions TDX Cat-Back Exhaust
This is the gold standard for 370Z exhausts. The TDX uses a true dual 2.5-inch design with an H-pipe crossover. It eliminates the factory Y-pipe restriction.
Power gains are around 12-15 whp on a stock car. The sound is deep and aggressive but surprisingly civil at highway speeds. The resonated test pipes option kills drone completely.
Build quality is top notch. T304 stainless steel with CNC mandrel bends. The welds are perfect. Fitment is spot on with no rattles or misalignment.
Downsides? Price. It’s one of the most expensive options at around $1,500. Also, the non-resonated version can still drone a bit with aftermarket headers.
Stillen Cat-Back Exhaust
Stillen has been making Nissan parts for decades. Their 370Z exhaust is a single 3-inch system that splits into dual tips. It’s lighter than stock by about 15 pounds.
Sound is aggressive but not obnoxious. There’s a slight drone around 2,500 rpm, but it’s manageable. The system is loudest at wide open throttle and quiets down during cruising.
Installation is straightforward. Everything bolts up using factory hangers. No cutting or welding required. The polished tips look great against the rear bumper.
Power gains are modest at 8-10 whp. But for the price (around $900), it’s hard to beat. This is the best bang-for-buck option.
ARK Performance Grip Exhaust
ARK designed the Grip system specifically to eliminate drone. They use a Helmholtz resonator chamber that cancels out problematic frequencies. It works incredibly well.
The sound is deep and mellow at idle. Under acceleration, it builds to a satisfying roar without harshness. Highway cruising is almost silent inside the cabin.
Build quality is excellent. The tips are massive and adjustable. You can push them out or tuck them in for a custom look. The system is fully polished and looks like jewelry under the car.
Downside is the price tag. Around $1,400. Also, some owners report the tips can loosen over time if not checked regularly.
Injen Evolution Cat-Back Exhaust
If you want loud, this is it. The Injen Evolution is a straight-through design with minimal muffling. It’s one of the loudest cat-back systems available for the 370Z.
Power gains are solid at 10-12 whp. The sound is raw and aggressive. You’ll hear every gear change and every throttle lift. It’s perfect for track days or cars that live at high rpm.
But daily driving can be tiring. There’s significant drone between 2,000 and 3,000 rpm. Cold starts are loud enough to wake neighbors. If you have a long commute, this might not be for you.
Price is reasonable at around $1,000. The tips are large and look aggressive. Just be prepared for the attention.
HKS Hi-Power Exhaust
HKS is a legendary name in Japanese performance. The Hi-Power system for the 370Z uses a straight-through muffler design with a unique sound. It’s not as loud as the Injen but has a distinctive note.
The tone is deeper than most systems. There’s a slight rasp at high rpm that some love and others hate. Build quality is excellent with T304 stainless steel and clean welds.
Power gains are around 8-10 whp. The system is lighter than stock by about 12 pounds. Fitment is good, but some owners report the tips sit slightly off-center.
Price is around $1,100. It’s a solid choice if you want a classic JDM sound without going overboard.
How To Choose The Right Exhaust
Picking the best exhaust for your 370Z depends on your goals. Here’s what to consider before buying.
Sound Preference
Do you want loud or subtle? Deep or raspy? Listen to sound clips online, but remember that recordings never capture the real experience. Try to hear systems in person at meets or track days.
- Deep and mellow: ARK Grip, Fast Intentions TDX resonated
- Loud and aggressive: Injen Evolution, Stillen
- Classic JDM: HKS Hi-Power
Drone Tolerance
Drone is the low-frequency hum that resonates inside the cabin at cruising speeds. Some systems have none, others are unbearable.
If you drive on the highway daily, avoid non-resonated systems. The ARK Grip and Fast Intentions TDX with resonated test pipes are the best for drone-free driving.
Performance Goals
Most cat-back systems add 8-15 whp. But if you plan to add headers, test pipes, or a tune, choose a system that flows well. The Fast Intentions TDX and Injen Evolution are the best for high-horsepower builds.
Budget
Prices range from $800 to $1,800. Don’t cheap out on a no-name system. Poor fitment and bad drone will ruin the experience. Stick with reputable brands.
Installation Guide
Installing a cat-back exhaust is a weekend DIY job. You’ll need basic tools and some patience. Here’s a step-by-step guide.
Tools Needed
- Jack and jack stands
- Socket set with extensions
- WD-40 or penetrating oil
- Rubber mallet
- Safety glasses and gloves
Step-By-Step Installation
- Jack up the rear of the car and secure on jack stands. Make sure it’s stable.
- Spray all exhaust bolts with penetrating oil. Let it sit for 10 minutes.
- Remove the factory exhaust. Start at the rear and work forward. Unbolt the hangers and muffler sections.
- Lower the factory system carefully. It’s heavy and awkward. Get a helper if possible.
- Test fit the new exhaust. Loosely bolt everything together before tightening.
- Adjust the tips for alignment. Make sure they’re centered in the bumper cutouts.
- Tighten all bolts from front to back. Use a torque wrench if you have one.
- Start the engine and check for leaks. Listen for rattles against the underbody.
- Lower the car and take a test drive. Listen for drone at different rpm ranges.
Most installations take 1-2 hours. If bolts are rusted, it can take longer. Use anti-seize on all bolts during reassembly for future removal.
Common Problems And Solutions
Even the best exhausts can have issues. Here’s what to watch for.
Drone At Highway Speeds
If your new system drones, try adding resonated test pipes or a Helmholtz resonator. Some owners install sound deadening in the trunk to reduce cabin noise.
Rattling Against The Chassis
Check all hangers and brackets. Sometimes the exhaust shifts during installation. Loosen the bolts, adjust the position, and retighten.
Check Engine Light
If you removed the factory catalytic converters, you’ll get a check engine light. Use a tune or O2 sensor spacers to fix it. Some systems come with anti-fouler adapters.
Exhaust System Types Explained
Understanding the different types helps you make the right choice.
Cat-Back Exhaust
This replaces everything from the catalytic converters back. It’s the most common upgrade. Easy to install and legal in most areas. Adds 8-15 whp.
Axle-Back Exhaust
Only replaces the mufflers and tips. Cheaper and easier to install. But power gains are minimal. Mostly for sound improvement.
Headers
Replace the factory exhaust manifolds. Adds 15-25 whp but requires a tune. Can be loud and may cause check engine lights. Not street legal in some states.
Test Pipes
Replace the catalytic converters. Adds power but makes the exhaust much louder. Illegal for street use in many areas. Expect drone.
Exhaust Material And Build Quality
Not all stainless steel is the same. Here’s what to look for.
T304 Stainless Steel
This is the best material. Corrosion resistant, durable, and looks great. All the top brands use T304. It costs more but lasts forever.
T409 Stainless Steel
Cheaper and less corrosion resistant. Can rust over time, especially in snowy climates. Fine for budget systems but not ideal for long-term use.
Aluminized Steel
Lowest cost but prone to rust. Avoid if you live in an area with road salt. Not recommended for daily drivers.
