8.4 kg gone from the back of the car, and a new voice from pure titanium. NISMO has just released a Sports Titanium Muffler for the Fairlady Z NISMO, and it is about 35% lighter than the factory exhaust.
That is not all. For owners of the new manual Z NISMO, NISMO also has a special track ECU that changes the speed limiter, so the car can run freely on a circuit.

Pure titanium, ready for tomorrow’s noise rules
NISMO uses a high-purity titanium alloy for the centre pipe and the rear silencer. The weights are NISMO’s own measurements. On a front-engined coupe, losing more than 8 kg right behind the rear axle is a nice gain.
NISMO says it tuned the sound for a light, clean tone at all engine speeds. The two big tailpipes get a black DLC (diamond-like carbon) coating with a NISMO logo. It looks special, and it stops the tips from changing colour from exhaust heat. The titanium pipes themselves will slowly change colour with use, which is normal for titanium.
The smart part is the paperwork. The muffler is a certified replacement exhaust that already meets Japan’s Phase 3 noise rules. Japanese site Car Watch reports that these stricter rules apply to cars built from 1 September 2027. NISMO lists the close-range noise at 77 dB for manual cars and 75 dB for automatics.
A track ECU for the manual Z NISMO
The second product is the NISMO Sports Resetting TYPE-1, a special engine computer (ECM). It changes only one thing: the speed at which the speed limiter starts to work. NISMO says the idea is to enjoy the Z NISMO on circuits and closed courses, safely and without the limiter cutting in.
NISMO has not published the new limit.
You cannot buy it online and fit it at home. It is only installed at the NISMO Omori Factory in Yokohama and at the NISMO Performance Center, and your original ECM is taken back when the new one goes in.
Why the manual is a big deal
When the RZ34 Z NISMO first arrived, it came only with a 9-speed automatic. For the 2027 model year, Nissan answered with a six-speed manual for the Z NISMO.
Nissan USA lists the Z NISMO at 420 hp from its twin-turbo 3.0-litre V6. The manual car gets an upgraded clutch and its own throttle and ignition timing tuning. The 2027 Z NISMO also gets GT-R-derived two-piece front brake rotors. In the US, the manual Z NISMO starts at $67,260.
So the new NISMO parts are aimed at exactly the owners who take their Z to the track.
Fan context: the Z and the aftermarket
The Fairlady Z story started in 1969 with the S30, and the Z has always been a tuner’s car. Japanese tuning shops have sold exhausts for the RZ34 since it arrived, so NISMO is not alone here.
Its main rival, the Toyota GR Supra, has a big aftermarket too, and its production run is now ending. That leaves the Z as one of the last six-cylinder, rear-drive Japanese coupes you can buy new. A factory-backed titanium exhaust that is street-legal for years to come is a strong argument for owners who want sound without trouble at inspection.
Our take
This is our opinion: we like it. Titanium, a real weight saving, a legal sound for the future rules, and a limiter change for track days are exactly what a Z NISMO owner wants. Black DLC tips also look much better than plain polished steel.
The bad points: ¥690,800 is a lot of money for an exhaust, and it is made to order. The ECU only changes the speed limiter, with no extra power. NISMO also does not say the new limit, and it can only be fitted at two NISMO sites in Japan. The muffler does not fit the manual regular Z, only the automatic.
