Lightweight Design Inherited from the SPEC-L (GR86/BRZ)

Just 10.2 kg for a Stainless-Steel Dual-Exit Exhaust System! (Stock Exhaust System: 16.2 kg)

The thickness of the silencer shells, pipes, and other components has been optimized to minimize weight. Despite featuring large-diameter Ø110 titanium tailpipes, the Hi-Power Spec-L GT retains the lightweight design inherited from the SPEC-L, helping bring out the GR86’s naturally agile sports performance.

Thin-Wall Construction

Optimized material thickness throughout the system reduces weight while maintaining the design’s performance requirements.
・Main Silencer Outer Shell Thickness: t0.5
・Mid Silencer Outer Shell Thickness: t0.6
・Pipe Wall Thickness: t0.8 (t1.2 mm in some sections)
・Outer Tailpipe Wall Thickness: t1.0 (Titanium)

Note: This exhaust system is designed with a focus on weight reduction and therefore uses thin-gauge materials for various components. Although durability testing has been conducted, impacts from road surfaces or obstacles, such as when driving over bumps, may cause deformation or damage to the exhaust system. Please exercise caution.

●Large-Diameter Ø110 Titanium Tailpipes

“Ø110 Titanium Tailpipes for a More Distinctive Rear View”

While retaining the lightweight design of the SPEC-L series, the tailpipe diameter has been increased from Ø94 mm to Ø110 mm.
The larger tailpipes create a bold, distinctive presence that complements the GR86’s rear styling, delivering the aggressive look expected of a sports exhaust system.
The titanium outer covers combine weight reduction with a premium finish.

●2-Way Tailpipe Finisher Adjustment

By changing the mounting position of the tailpipe finishers, the protrusion of the inner tailpipes can be adjusted in two stages.
Choose between Style 1, which positions the finishers further outward to emphasize the presence of the large-diameter Ø110 titanium tailpipes, and Style 2, which offers a cleaner appearance with a more integrated look alongside the body.
This unique customization feature of the SPEC-L GT allows users to tailor the rear view to their personal taste and preferred styling.
