2017-2022 Infiniti Q60

Building upon the exceptional TYPE-R Single, which revealed the true potential of the INFINITI Q60 through lightweight construction, razor-sharp response, and pure titanium sound, the Expreme-Ti lineup expands with the TYPE-D Dual—not as a replacement, but as a new expression.

Developed to preserve the same uncompromising full-titanium philosophy, TYPE-D DUAL delivers a broader rear presence, deeper sound character, and a refined balance that complements the Q60’s modern sports-coupe identity.

Function Over Form — Fully Realized

After extensive prototyping and rigorous testing, the TYPE-D Dual Full Titanium Exhaust System was completed with TOMEI’s core principle at its foundation: Function over Form. Every element is engineered to enhance performance while maintaining balance, precision, and sound purity.

Full Titanium Construction

Crafted entirely from full titanium, TYPE-D reduces system weight by nearly 40% compared to the OEM exhaust, improving throttle response, handling dynamics, and overall driving engagement. Titanium’s strength and heat resistance ensure durability under demanding conditions without sacrificing refinement.

True Dual, Straight-Through Design

The Φ80.5mm true dual layout and straight-through internal structure optimize exhaust flow, delivering consistent performance gains and smooth power delivery across the rev range—perfectly matched to the twin-turbo VR30DDTT engine.

Signature Titanium Sound

TYPE-D produces a deep, dry titanium tone with a controlled low-frequency presence. At idle, it remains composed and refined. Under throttle, it sharpens into a crisp, resonant note that highlights the V6’s character—distinct, aggressive, and unmistakably titanium.

Precision Fitment & Complete Kit

Designed as a direct-fit system, TYPE-D includes all required installation hardware, along with Bolt Smooth Paste to help prevent bolt seizure under high heat conditions.
