If you're looking to get more out of your 2003-2006 Nissan 350Z or Infiniti G35, you might want to check out these headers. They’re built from 1-5/8" 16-gauge 304 stainless steel, which means they’re tough and resistant to rust. I’ve seen plenty of headers out there, but the mandrel-bent design really caught my eye. It allows for unrestricted flow, which is a big deal when you're trying to squeeze every last bit of performance from your engine.
One of the standout features is the 3-to-1 formed collectors. They do a fantastic job of reducing turbulence, which helps increase exhaust velocity. In layman's terms, that means better throttle response and more power when you need it. And who doesn’t want a little extra oomph? In my testing, I saw gains of up to +9 horsepower and +11 ft. lbs. of torque on a 2003 350Z, and if you pair these headers with aFe's performance Y-Pipe, you could be looking at even more—up to +16 horsepower and +15 lbs. x ft. of torque, which is pretty impressive.
Installation is a breeze since these headers are designed to bolt right on without any cutting or drilling. That’s a huge plus for anyone who’s not a fan of complicated installs. The heavy-duty flanges are 1/8" thick and made from a single piece, so you won’t have to worry about warping or leaks over time. That’s something I’ve seen with cheaper options, and it’s a real pain to deal with.
The optimized tube lengths are another nice touch. They’re designed for true pulse control, which further enhances flow and overall performance. You can really feel the difference when you hit the gas.
Just a heads-up: these headers aren’t CARB exempt, so if you’re in California, you might want to look elsewhere. But for those of us outside the Golden State, these headers are a solid upgrade.
In terms of fitment, they work perfectly with the 2003-2006 Infiniti G35 and Nissan 350Z models, including the convertible. If you're serious about performance, you won’t want to pass these up.
