Tomei EXPREME Ti Titanium Muffler - Subaru WRX STI / WRX / Forester XT (VAB/VAG/SJG) - JDM Spec
Tomei's EXPREME Ti mufflers are full-titanium competition exhausts with a racing-straight layout and minimal bends for maximum exhaust flow. The three-section slip-joint construction uses springs and clamp bands instead of mid-pipe flanges, saving further weight.
This single-exit system uses a Φ80 mm main pipe, Φ120 mm sub-silencer and Φ152 mm main silencer, and weighs 6.9 kg against 23.1 kg for the factory exhaust – a 16.2 kg saving. It connects to the factory front pipe.
Fitment
This listing covers the Subaru WRX STI (VAB), WRX (VAG – sold in Japan as the WRX S4) and Forester XT (SJG), Japanese-market specification.
