Like most cars, the Nissan 350Z is rather quiet from the factory. If you're a car enthusiast, you'd probably like a little more of a deep sound and some more grunt from the car when you give it the beans. Unfortunately, this just isn't how Nissan makes them. The good news is that the aftermarket has stepped in, and on a sports car like the 350Z, there's of options if you're looking to fix this. These exhaust systems also improve flow and reduce restriction, improving the car's performance with more horsepower and torque.
We've rounded up the best 350Z exhaust systems and compared them. No matter your budget, or how loud you want your car to be, we've found something for you.
Invidia is one of the most popular brands for exhaust systems, not just for the 350Z, but for all performance vehicles. Their Gemini catback exhaust is made from stainless steel, with 60mm wide piping and 110mm exhaust tips.
This exhaust system is more free flowing than the stock one, giving some small power and torque increases. It has a muffler and resonator for each side, designed to keep the noise levels down a bit but still giving an aggressive sound.
If you're looking for a more aggressive sound, but don't want your 350Z to sound obnoxious and tinny, then this is the best choice. It has the high quality fit and finish you'd expect from Invidia and sounds amazing.
The Tomei Expreme Titanium exhaust has made a great name for itself around various car communities, and it's also available for 350Z. It's known for being one of the loudest systems and having excellent build quality.
This is a single exit exhaust system with a wide burnt titanium tip. The piping is bent to create as little restriction as possible, and it's designed for maximum weight reduction. The piping is 80mm wide, and it has a massive 115mm exhaust tip. It includes an optional silencer that goes in the tip to keep sound down when you desire.
If you want the maximum flow and added power from your exhaust, and you're not worried about being too loud, then this is made for people who think like you. The Tomei Expreme is unapologetically loud, and it sounds and looks great.
Another great exhaust for the 350Z from Invidia, the N1 catback system is made for those who'd like something louder and more free-flowing than the Invidia Gemini. This is another dual-exit exhaust, but it's designed with fewer bends in the piping. The center resonator and mufflers on each side keep drone down, but the sound comes alive when you rev up your engine, giving you some nice higher pitched tones along with pops and crackles.
The APEXi N1 is another popular choice for the Nissan 350Z. The straight-through muffler design makes it more free-flowing compared to the stock system, gives a more aggressive sound, but helps to sculpt the raw engine noise into something pleasing to the ears. APEXi's products are high quality and durable, and this is no exception, with its 304 stainless steel and robotic tig welds.
This exhaust system is designed for those who don't want much extra sound, but would like to free up the restriction in the factory exhaust for some added horsepower and torque. The Megan Racing catback is designed in a similar way to the OEM exhaust system, but with larger piping. The quality is excellent, and all of the tubing is mandrel bent and polished.
HKS is a popular Japanese tuning company, and they sure know their way around a JDM car like the 350Z. Their Hi-Power exhaust system is designed with free-flowing mufflers and resonators that keep the car from sounding tinny or shrill, and help to prevent drone, but it still lets out the aggressive tone you want. The system has two long pipes, made from 60mm stainless steel tubing, with an H-pipe crossover. This extra diameter increases the flow from the stock exhaust, not only giving you more sound, but more performance.
Rev9 offers a good budget catback exhaust for the 350Z. If you're looking to free up that factory exhaust restriction and make your car louder, along with a small increase in power, this will do it. While at the price, you can't expect the excellent quality of higher end systems, this will still hold up and get the job done, and it won't break the bank.
