Tomei Expreme Ti Titanium Exhaust System - Nissan 350Z

The Tomei Expreme Ti titanium exhaust for the 2003 to 2008 Nissan 350Z trades the heavy factory system for a single exit catback that weighs a fraction as much. Tomei tuned this system for overall VQ35DE engine performance rather than chasing a peak dyno number, selecting the tube length and diameter to suit the character of that engine.

Weight is the headline

From the Y pipe to the muffler exit, the factory 350Z exhaust comes in around 48 lb. The Expreme Ti drops that to roughly 13 lb (5.9 kg). That mass sits behind the rear axle, so removing it is felt in how the car rotates, not just on the scale.

2003-2008 Nissan 350Z with the VQ35DE. This is a catback system; pair it with a performance Y pipe if you want to open up the mid section as well.

In the box

Titanium exhaust work is sensitive to thread galling, which is why Tomei supplies the smooth paste for the flange bolts; use it on assembly. The removable sound reducer gives you a quieter option for street use.
