TOMEI Full Titanium Muffler EXPREME Ti Type-R Single Exit Catback Exhaust – 2022+ Subaru WRX

The TOMEI EXPREME Ti Type-R Single Exit Catback Exhaust brings TOMEI’s signature full titanium construction, lightweight design, and aggressive racing sound to the 2022–2026 Subaru WRX. Built around TOMEI’s concept of creating products for ultimate driving pleasure, this exhaust is designed to improve the way your WRX sounds, feels, and responds.

Using optimized pipe sizing, minimal bends, and full titanium construction, TOMEI reduces exhaust weight dramatically while improving exhaust flow. The result is a single-exit catback system that weighs just 17.9 lbs, saving approximately 30.2 lbs compared to the factory exhaust.

Why We Like It

This is the more aggressive, lightweight option in TOMEI’s VB WRX exhaust lineup. The single-exit Type-R layout cuts serious weight, gives the WRX a louder and more motorsport-inspired tone, and delivers the iconic titanium TOMEI look. If your goal is maximum character and minimum weight, this is the one.

Sound Levels

Sound levels tested at 3800rpm:

• Sound Reducer V2: 89dB
• Sound Reducer: 95dB
• Without Sound Reducer: 99dB

Tail Pipe

The tail pipe is made from titanium with a 115mm / 4.5" diameter and 1mm wall thickness. The straight-cut design gives the exhaust a race-focused appearance, while the burnt titanium blue gradation and laser-etched EXPREME Ti logo provide the signature TOMEI finish.

Silencer Design

The silencer case is constructed from titanium with a 152mm shell diameter and 1mm wall thickness. The oversized shell design helps optimize exhaust gas flow, while the embossed TOMEI logo and heat gradation finish complete the premium EXPREME Ti look.

Internal Construction

• Titanium Punched Mesh: 1mm titanium construction with a 32.6% open slot ratio for high flow and a clean racing tone.
• Long-Fiber Glass Wool: Designed to last longer than traditional fiberglass packing under extended high-temperature use.
• Precision Titanium Welds: TOMEI’s welding process delivers strength, durability, and a high-quality finish.

Clamp Band & Connecting Springs

The exhaust sections use clamp bands and connecting springs instead of a conventional flange-only design. This helps keep the pipe joints secure while allowing controlled movement to absorb vibration, heat expansion, and stress during aggressive driving.
