We’ve covered a huge amount of aftermarket upgrade choices for 370Z owners in our previous guides, so whether you’re looking for an intake, exhaust, coilovers, headers or going to new extremes with a supercharger or turbo kit, we’ve got you covered!

This time, we’ve listened to your requests to get the best potential out of your 370Z exhaust system, and many of you have been considering going down the test pipes route to get the air flowing in the most efficient way possible.

Test pipes are an extremely simple and cheap bolt-on modification that can potentially offer around 10hp gains, there’s certainly not many mods on the market that can make these kind of gains for a couple of hundred bucks!

Sounds too good to be true, right? Well, there are unfortunately a few drawbacks to running test pipes, but if power gains are your main concern then nothing else is going to match them.

If you’ve looked at test pipes already, you would’ve seen that they state they’re made for ‘off-road use only’. The reason for this is that most pipes are essentially a pipe which bypasses the catalytic converter. Perfect for performance gains but not so perfect when it comes to passing emissions testing.

Other disadvantages are that it may well bring up your CEL (engine warning light), but there are plenty of simple guides online on how to get around this. You’re also going to have to prepare yourself for some SERIOUSLY loud noises, but that’s not always a bad thing!

For some of you, these niggles won’t be an issue and you’re purely looking for making the most of your 370Z, so we’ve created this guide to help you.

So if you can deal with these minor drawbacks and you’re ready to release those extra ponies from under the hood, check out our selection. We’ve done extensive research and narrowed down some of the best choices available on the 370Z market.

Resonated test pipes provide sound-deadening with barely any changes in performance, so unless you want to set off alarms when you go for a casual drive, these are going to be the better option for you.

For those that need to pass emissions testing, high-flow cats are going to be the best route for you to go down. With that being said, high-flow cats also have their own disadvantages, combined with high-costs and test pipes are far less likely to go wrong due to their simplicity.

We’ve written this guide to explain the differences and help you decide which test pipes are best for your needs.

Motordyne 370Z Advanced Resonance Tuning (ART) Test Pipes

• Manufacturer: Motordyne
• Fitment: Nissan 370Z (Z34)
• Value for money: 🔥🔥🔥🔥🔥
• Purchase link: Buy the Motordyne 370Z Advanced Resonance Tuning (ART) Test Pipes here

Our comment: We go straight into our list with the most expensive option, but arguably the best. Where most test pipes are a simple connecting pipe, Motordyne have gone out of their way and done countless hours of research to bring this unique product to the market with separate resonance chambers.

These are well-known for being quieter as well as removing some of the less-desireable sounds that can often come with test pipes such as excessive rasp and drone to bring you the ultimate combination of performance and harmonics in a great-looking package.

Sure, they’re the most expensive, but these are the perfect solution for those of you that want the ultimate product for your Z. Unsurprisingly, these are the most popular choice among owners.

Manufacturer description: “Through countless hours of research and development a new path has been explored in the never-ending quest for performance. A method of directly altering exhaust harmonics for enhanced performance and sound, Advanced Resonance Tuning (ART).“

“ART pipes for increased power and torque without the drastic increase in loudness normally associated with test pipes. ART pipes provide the quietest, smoothest, deepest sound of any test pipe while greatly reducing or eliminating rasp and drone. The difference in sound is not subtle. They’re not conventional test pipes. They’re ART pipes!“

Berk 370Z Non-Resonated Test Pipes

• Manufacturer: Berk
• Fitment: Nissan 370Z (Z34)
• Value for money: 🔥🔥🔥🔥🔥

Our comment: They’re one of the cheapest offerings on our list but there’s been no compromise on quality here, which is why the Berk test pipes are the most popular non-resonated cats available. Sure, they’re going to be loud as they’re a straight-through pipe, but they’re extremely well made and sound awesome.

Many owners have reported a much louder, deeper sound from the exhaust but with very little drone considering that it’s a straight-through. For those of you that don’t have emissions or sound concerns, these are the perfect value-for-money choice.

Manufacturer description: “Our highly anticipated 2007-up test pipes are now available! Features fully gusseted and plated support brackets, the strongest in the industry.“

“Includes the same leak free soft crush graphite collector gaskets found in our 07- up HFC’s and secondary O2 sensor bungs for wideband tuning or AF monitoring.“

Fast Intentions (F.I.) Resonated 370Z Test Pipes

• Manufacturer: Fast Intentions
• Fitment: Nissan 370Z (Z34)
• Value for money: 🔥🔥🔥🔥🔥
• Purchase link: Buy the Fast Intentions 370Z Test Pipes here

Our comment: Another extremely popular choice once again comes from Fast Intentions as they bring another fantastic product to the market. You always can count on incredible quality and customer support from these guys.

These resonated pipes are another strong contender for the win here, and for many owners they are the best test pipes out there. If you’re determined to go with F.I. but looking for non-resonated test pipes, you can find them here.

Manufacturer description: “These resonated test pipes are the premier upgrade for all 370Z owners looking to maximize performance from their VQ37VHR V6 engine. Our resonated test pipes effectively increase low-end torque and maximize power throughout the entire RPM band.Your overall exhaust volume will increase.“

“Built as a direct OEM replacement, resonated test pipes are designed to be an addition to your cat back exhaust system. We maximize performance by eliminating your OEM catalytic converters, increasing the tubing diameter, and adding straight-through perforated core resonators to free up back pressure. This addition is ideal for force inducted applications because of its straight through design, eliminating virtually all restriction.“

ISR Performance Resonated 370Z Test Pipes

• Manufacturer: ISR Performance
• Fitment: Nissan 370Z (Z34)
• Value for money: 🔥🔥🔥🔥

Our comment: These resonated pipes from ISR Performance are the cheapest option on our list, but still offer decent quality and fitment. For a cheap resonated setup, you can’t really go wrong with these.

They also have a non-resonated option at just $169.00, however we would prefer to stump up a little extra cash for the more popular Berk option.

Manufacturer description: “The ISR Performance resonated test pipes are constructed using high-quality stainless steel. These resonated test pipes utilize stock flange locations so they can be used with stock components or aftermarket (Provided they aftermarket components use stock style flanges and mounting locations.)“

“These test pipes will eliminate your catalytic converter, and are designed for off-road use only. Utilizing a small resonator, the ISR Performance resonated test pipes will help cut some of the rasp of the exhaust note of your modified VQ while still providing much better exhaust gas flow than the OEM catalytic converter. These will help add the maximum amount of horsepower and torque to your VQ, especially when paired with the ISR Y-pipe and exhaust!“

Invidia Non-Resonated 370Z Test Pipes

• Manufacturer: Invidia
• Fitment: Nissan 370Z (Z34)
• Value for money: 🔥🔥🔥🔥

Our comment: Invidia are always a solid choice when it comes to exhaust parts and their test pipes are no exception.

Owners have generally found this setup to provide more rasp and drone than the Berk alternative which is at a similar price-point, but we have no doubt you’ll be satisfied if you’re looking to pair these with your current exhaust setup.

Manufacturer description: “Installing the Invidia Test-Pipe is a great way to free up horsepower and increase the sound of your exhaust. By removing the stock catalytic converter you are allowing a greater volume of exhaust gases to pass through the exhaust system, thereby giving you better throttle response, increased power, and better gas mileage.“

Motiv Concepts Non-Resonated 370Z Test Pipes

• Manufacturer: Motiv Concepts
• Fitment: Nissan 370Z (Z34)
• Value for money: 🔥🔥🔥🔥

Our comment: They may not be one of the most well-known brands on the market and certainly not one of the most popular choices, but we’ve heard many positive things about these great-looking Motiv Concepts test pipes.

They’re certainly not new to the game, bringing over 20-years experience in building high-quality show and race cars. If you decide to go with these as something a little different, we’d love to hear your thoughts.

Manufacturer description: “There’s no better way to maximize the performance of your vehicle than with a set of high-performance test pipes. Get rid of the restrictive stock catalytic converters and let your engine breathe the way it was meant to be. Motiv Concepts test pipes for the Nissan 370Z does just that. Featuring our signature beautiful brushed finish on 2.5-inch of U.S. made RathGibson tube. Complete bolt-on with all-new hardware, ready to go.“

AAM Competition Non-Resonated 370Z Test Pipes

• Manufacturer: AAM Competition
• Fitment: Nissan 370Z (Z34)
• Value for money: 🔥🔥🔥🔥

Our comment: Many owners are happily running the AAM Competition test pipes. These are well-known for being particularly raspy, but if that’s not a concern for you then they’re a great choice.

For us, we would personally struggle to deal with so much rasp on a daily basis as we know how frustrating it can get when trying to drive around normally on a daily driver.

Manufacturer description: “For enthusiasts looking for the highest possible exhaust flow from their vehicles, removing factory catalytic converters in favor of 2.5″ diameter race or “test” pipes is the most efficient upgrade available.“

“The AAM Competition 2.5′ Test Pipes replace the factory Nissan 370Z High Flow Cats and are designed purely for off-road performance. Each unit is hand assembled at AAM Competition’s manufacturing facility in the U.S.A., using raw 304-grade stainless steel components. Exhaust flows freely from the engine without the restriction of catalytic converters, and peak engine power and torque are greatly increased.“

Our winner

Our winner is the Motordyne ART Test Pipes.

To pick our winner from this choice of 370Z test pipes we looked at a number of criteria; performance, quality, sound, popularity and design.

Based on these criteria we have chosen the Motordyne ART Test Pipes to be our winner.

Motordyne Advanced Resonance Tuning Pipes

There’s no question that test pipes are a simple product to provide the maximum possible exhaust flow to give the ultimate performance. However, Motordyne have gone above and beyond with their ART pipes to tick all the right boxes to make the perfect all-around solution.

We can’t question that these come at a price though, so if it’s a little more than you’d like to spend, we would definitely recommend the Berk non-resonated and Fast Intentions resonated. If you’re on a tight budget, the ISR pipes are a bargain.

Thank you for reading our Nissan 370Z Test Pipes guide

We hope that you’re now confident in choosing the right product for your needs to give your Nissan the much-needed power upgrade it should’ve left the factory with!
