The Nissan 350Z’s VQ35 engine responds noticeably to a free-flowing exhaust, both in sound and throttle response. Finding the best exhaust for Nissan 350Z can be tough because there are so many options, but we are here to simplify it for you. This guide covers top picks based on sound, performance, and budget, so you can make a smart choice.
Best Exhaust For Nissan 350Z
When you start looking for a new exhaust, you will see three main types: cat-back, axle-back, and header-back systems. Each one changes the sound and power differently. Cat-back systems are the most popular because they replace everything from the catalytic converters back, giving a nice sound and a small power gain. Axle-back systems only change the mufflers and tips, which is cheaper but gives less performance. Header-back systems are the most expensive and loud, replacing everything from the headers back.
Your choice depends on what you want. Do you want a deep rumble or a loud scream? Do you want more horsepower or just a better sound? Let’s break down the top exhausts for the 350Z.
Top Cat-Back Exhaust Systems
Cat-back systems are the sweet spot for most owners. They offer a good balance of sound, performance, and price. Here are the best ones.
Injen SES Cat-Back Exhaust
This system is known for its deep, aggressive tone without being too loud. It uses a straight-through design with a large resonator to control drone. The sound is smooth at idle and opens up nicely when you hit the gas. You will get a noticable bump in horsepower, around 10-15 whp on a stock car. It is made from T-304 stainless steel and comes with polished tips. The fitment is excellent, and installation is straightforward. Some users report a slight drone at highway speeds, but it is not overwhelming.
Motordyne Shockwave Cat-Back Exhaust
If you want the best sound and performance, the Motordyne Shockwave is often considered the gold standard. It uses a unique Helmholtz resonator design that cancels out drone completely. The sound is deep, exotic, and refined. It is also one of the lightest systems available, saving about 20 pounds over stock. Power gains are solid, around 12-18 whp. The price is high, but you get top-tier quality. The only downside is the cost and sometimes longer wait times for shipping.
Stillen Cat-Back Exhaust
Stillen has been making parts for Nissan for a long time. Their cat-back exhaust is a great all-around choice. It has a mellow, sporty tone that is not too loud for daily driving. The sound is deeper than stock but still refined. Performance gains are modest, around 8-12 whp. It is made from mandrel-bent stainless steel and fits perfectly. The price is reasonable, making it a good value. Some people find it too quiet if they want a loud exhaust.
Best Axle-Back Exhaust Options
Axle-back systems are a good choice if you want to save money and only change the sound a little. They are easier to install and cheaper. But they don’t add much power.
Megan Racing Axle-Back Exhaust
This is a budget-friendly option that gives a deeper, louder sound than stock. It is made from stainless steel with polished tips. The sound is more aggressive, but there can be some drone at highway speeds. Installation is simple, and it fits well. It is a good choice if you want a louder car without spending a lot. The build quality is decent for the price, but not as good as higher-end systems.
Invidia N1 Axle-Back Exhaust
The Invidia N1 is a popular choice for a reason. It has a deep, throaty sound that is not too loud. It is well-made from T-304 stainless steel. The tips are large and look great. Drone is minimal, which is nice for daily driving. Power gains are small, maybe 2-4 whp. It is a solid upgrade if you want a better sound without breaking the bank. Some people think it is still too quiet.
Header-Back Exhaust Systems For Maximum Performance
If you want the most power and loudest sound, go with a header-back system. This replaces everything from the headers to the tips. It is expensive and loud, but it gives the biggest gains.
Motordyne Art Pipes And Shockwave Combo
This is the ultimate setup for the 350Z. The Art Pipes replace the stock catalytic converters with high-flow cats or test pipes. Combined with the Shockwave cat-back, you get a huge power gain, around 25-35 whp. The sound is incredible, deep and exotic. It is also very loud, so be ready for that. Drone is almost non-existent thanks to the Helmholtz resonator. This is a top-tier setup for serious enthusiasts. The cost is high, and installation is more complex.
Fast Intentions Cat-Back With High-Flow Cats
Fast Intentions makes custom exhausts that are built to order. You can choose the muffler type, tip style, and pipe diameter. Their cat-back paired with high-flow cats gives a great sound and solid power gains. The sound is deep and aggressive, with minimal drone. The build quality is excellent. The downside is the wait time, as they are made to order. The price is also on the higher side.
How To Choose The Right Exhaust For Your 350Z
Choosing the right exhaust depends on your goals. Here are some things to think about.
- Sound Preference: Do you want a deep rumble, a loud scream, or something in between? Listen to sound clips online to get an idea.
- Performance Goals: If you want maximum power, go with a header-back system. For a good balance, a cat-back is best. Axle-backs give minimal power gains.
- Budget: Axle-backs are the cheapest, cat-backs are mid-range, and header-backs are the most expensive.
- Drone Tolerance: Some exhausts have drone at highway speeds. If you drive long distances, look for systems with resonators or Helmholtz chambers.
- Installation Difficulty: Axle-backs are easy to install yourself. Cat-backs are moderate. Header-backs are more complex and may need a shop.
- Local Laws: Check your local noise and emissions laws. Some exhausts are too loud or remove catalytic converters, which can be illegal.
Installation Tips For Your New Exhaust
Installing an exhaust on a 350Z is not too hard, but it helps to have the right tools. Here is a step-by-step guide for a cat-back installation.
- Jack up the car and secure it on jack stands. Make sure it is stable.
- Spray all the bolts with penetrating oil. Let it sit for 10 minutes.
- Remove the old exhaust. Start at the muffler and work forward. You may need to cut the bolts if they are rusted.
- Compare the new exhaust to the old one. Make sure it fits correctly.
- Install the new exhaust from the front to the back. Use the new gaskets and hardware that came with the kit.
- Tighten all bolts hand-tight first, then torque them to spec. Do not overtighten.
- Check for leaks by starting the car and listening. If you hear a hiss, tighten the bolts a little more.
- Lower the car and go for a test drive. Listen for any rattles or drone.
If you are not comfortable doing it yourself, a muffler shop can install it for around $100-$200. It is worth the money if you don’t have the tools or experience.
Sound Comparison: Which Exhaust Is Loudest?
Sound is subjective, but here is a general ranking from quietest to loudest for cat-back systems.
- Stillen: Mellow and refined, good for daily driving.
- Injen SES: Deep and aggressive, but not too loud.
- Invidia N1: Throaty and sporty, a bit louder than Injen.
- Motordyne Shockwave: Loud and exotic, but no drone.
- Fast Intentions: Can be very loud depending on options.
If you want the loudest possible, go with a header-back system with test pipes. That will be ear-splittingly loud. But be careful, it might attract unwanted attention from the police.
