Nissan 350Z / 350Z Roadster Valved Exhaust System (2002-2008)

Which valved exhaust for a Nissan 350Z coupé or Roadster?

The Rog system for the Nissan 350Z, in coupé and Roadster form, is a valved cat-back exhaust in 304 stainless steel or titanium, built to your VIN for the naturally aspirated VQ35 V6 with 280 to 313 hp depending on model phase. Valves open, the VQ's gravelly timbre is there from idle and turns furious higher up the rev range; closed, it fades into the background for everyday journeys.

Sound, options and fitting in detail: our Nissan 350Z guide.

A Z-line coupé built from 2002 to 2008, the 350Z relies on a naturally aspirated VQ V6, fierce and eager to rev, whose rasping tone has become a cult favourite among Japanese car enthusiasts; the page credits it with 280 hp and 363 Nm.

From the factory, this character arrives muffled; with the Rog valved cat-back and the valves open, the VQ tone regains its rasping grain from idle, then its fury at high revs, with a few crackles on the overrun, before fading away when you close the valves. The 370Z, standard and Nismo alike, have other pages; for the 350Z, the serial number is checked before manufacturing.

Allow about two hours for fitting, no welding, using clamps and gaskets; if the coupé has factory valves, their control is retained, otherwise the two-button Rog remote opens and closes them.

Further upstream, the “Manifold” option replaces the front part housing the VQ’s catalytic converter; on this non-turbo V6, a suitable map only extracts a modest gain, roughly 3 to 8%, whereas the character changes completely. A 350Z used on the road will keep the 200-cell version and its emissions control; the 100-cell will be accepted or refused depending on the vehicle and your country’s rules, and the decat version remains a track part. 304 stainless steel to face the winter, titanium to save around 40% in weight: the round exits follow your choice.
