Exhaust Systems

Tomei's Expreme Ti Series cat-back exhausts are constructed entirely from titanium, offering a significant weight reduction and free-flowing performance. Designed to deliver sharper throttle response and a deep, aggressive sound, these systems are available for popular platforms like the Nissan 400Z (RZ34), Infiniti Q50, and Hyundai Genesis Coupe 2.0T. Every system is engineered for ideal piping diameter and minimal restriction—perfect for street and track use.

Camshafts & Valvetrain

Maximize power across the RPM range with Tomei camshafts. The Procam series, such as the 270-11.00 for the Toyota 2JZ-GTE, is engineered for aggressive lift and duration, unlocking peak top-end horsepower. For milder applications, the Poncam line offers a balance of performance and drivability. Tomei also supports the 1JZ-GTE, SR20DET, and 4A-G platforms, making them a go-to source for valvetrain tuning.

Engine Internals

For high-horsepower builds, Tomei’s engine internals deliver unmatched strength and performance. The Tomei 4.1L Stroker Kit for the VR38DETT increases displacement, resulting in massive gains in torque and mid-range power—ideal for serious GT-R performance. Solid pivot kits and valvetrain upgrades for engines like the SR20DET ensure stability at high RPM and under heavy load, making them essential for track or drift applications.

Fuel Management & Supporting Mods

Tomei also produces precision fuel delivery components such as the highly rated Tomei Fuel Pressure Regulator, known for consistent performance and reliability in high-output fuel systems. These parts provide tuners with the confidence and control required in forced induction and race-level builds.
