Tomei Expreme TI Full Titanium Catback Exhaust | VQ37VHR 370Z G37 Q50 | 70mm | 28lb Weight Savings

This Tomei Expreme TI Full Titanium Exhaust System is the flagship catback engineered specifically for the VQ37VHR 3.7L V6 found in the 2009-2011 Nissan 370Z Z34, 2008-2013 Infiniti G37 Coupe V36 and Sedan V36, and 2014-2017 Infiniti Q50 V37, and it represents the absolute pinnacle of JDM motorsport design because every inch from the dual front pipes to the Y-pipe, mid-pipe, muffler section, and dual burnt titanium tips is fabricated from 100% Grade 1 pure titanium, not titanium tips on stainless piping, which slashes over 28 lbs off the rear of your Z/G/Q compared to the heavy OEM steel system for a measurable improvement in acceleration, braking, and rear weight bias that you can actually feel on the street and track, while the full 70mm mandrel-bent diameter throughout maintains optimal exhaust gas velocity to increase scavenging and unlock dyno-proven horsepower and torque gains across the entire RPM range with the biggest gains from 4500rpm to 7500rpm where the VQ37VHR makes peak power, and the sound is what makes the Expreme TI legendary because titanium’s natural resonance produces a raw, high-pitched, exotic F1-style scream at wide-open throttle that no stainless system can replicate, yet Tomei’s race-developed straight-through muffler uses internal sound tuning chambers to keep highway drone and cabin resonance surprisingly controlled at cruising RPM so you can daily it without going deaf, and every weld on the system is hand-TIG’d in Japan by Tomei master fabricators with flawless aerospace-grade stack-of-dimes bead consistency that proves this is not mass-produced, plus it uses thick CNC-machined titanium flanges at every connection point to prevent the warping and exhaust leaks that plague cheaper systems after repeated heat cycles, and the signature dual burnt titanium tips with laser-etched Tomei Expreme TI branding are angle-cut and develop deeper blue, purple, and gold hues with heat cycles for that authentic titanium patina enthusiasts hunt for, while the entire system is a true direct bolt-on that uses all factory mounting points and included titanium hardware to mate perfectly to your stock catalytic converters or aftermarket test pipes with no cutting, welding, or modifications required, and it’s designed to tuck extremely tight to the chassis for maximum ground clearance which is critical for lowered Z34/V36/V37 platforms so you won’t scrape on driveways or speed bumps, and because it’s pure titanium it is completely immune to rust, corrosion, and salt damage so it will outlast the car in any climate, making the Expreme TI the lightest, loudest, most exotic, and most respected catback you can put on a VQ37VHR, backed by Tomei’s decades of Super GT and D1GP motorsport heritage, built for owners who want the ultimate in Japanese craftsmanship, performance, weight savings, and a VQ exhaust note that dominates every car meet and track day.
