Vehicle Compatibility

The Tomei Expreme Joint Pipe fits:

• Toyota 86
• Scion FR-S
• Subaru BRZ

Chassis Codes

• ZN6
• ZC6

Engine

• FA20 2.0L Boxer Engine

Whether your vehicle is naturally aspirated or turbocharged, improved exhaust flow can help unlock additional performance.

Why Upgrade the Factory Joint Pipe?

The factory joint pipe measures approximately 54mm in diameter and includes flattened sections that restrict airflow.

Tomei’s solution features:

• 60.5mm diameter piping
• Full SUS304 stainless steel construction
• Mandrel-style design
• Improved exhaust efficiency

The result is reduced restriction and smoother exhaust flow throughout the system.

Better Exhaust Flow

The larger diameter allows exhaust gases to exit more efficiently.

Benefits include:

• Reduced backpressure
• Improved scavenging
• Better throttle response
• Increased horsepower potential

Maximizes Header Performance

Many enthusiasts install aftermarket headers expecting significant gains.

Unfortunately, the restrictive factory joint pipe often limits those gains.

The Tomei Expreme Joint Pipe helps aftermarket headers perform as intended by eliminating a major bottleneck downstream.

Full SUS304 Stainless Steel Construction

Tomei utilizes premium SUS304 stainless steel throughout the pipe.

Advantages include:

• Excellent corrosion resistance
• Long-term durability
• High-temperature strength
• Attractive appearance
• Resistance to oxidation

Unlike mild steel components that can rust over time, SUS304 stainless steel is built to survive years of street and track use.

Lightweight Design

Weight reduction is a major priority for performance enthusiasts.

Tomei Joint Pipe Weight

• 1.5 kg (3.3 lbs)

Factory Joint Pipe Weight

• 2.0 kg (4.4 lbs)

While a half-kilogram reduction may seem small, every pound removed contributes to improved vehicle performance.

As every 86 owner knows, adding power is expensive. Losing weight is often the cheaper horsepower.

Complete Installation Kit Included

Tomei includes everything needed for installation:

• Joint pipe gasket
• Flange bolts
• Stud bolts
• Flange nuts
• Smooth paste
• Upgraded titanium exhaust thermal bandage

The included thermal wrap helps manage underbody temperatures and protects nearby components from excessive heat.

One-Piece Welded Construction

Unlike some aftermarket alternatives, the Tomei Expreme Joint Pipe uses a fully welded one-piece design.

Benefits include:

• Improved strength
• Better durability
• Consistent internal diameter
• Reduced turbulence

Additional internal weld beads provide rigidity while maintaining excellent exhaust flow characteristics.

Performance Benefits

Owners commonly report improvements in:

Throttle Response

The engine responds more quickly to throttle inputs due to reduced exhaust restriction.

Midrange Torque

Improved exhaust scavenging can help strengthen torque delivery throughout the powerband.

Exhaust Sound

The larger-diameter pipe often produces a deeper, more aggressive exhaust note without excessive drone.

Future Modification Support

The joint pipe provides additional headroom for:

• Catless headers
• Equal-length headers
• Turbo kits
• Supercharger systems
• High-flow exhaust systems

Is It Worth Buying?

For enthusiasts already upgrading their FA20 exhaust system, the Tomei Expreme Joint Pipe is one of the smartest supporting modifications available.

It eliminates a known factory restriction, improves exhaust efficiency, reduces weight, and complements other performance upgrades.

If you’ve already invested in headers and a cat-back exhaust, leaving the stock joint pipe in place is like trying to drink a milkshake through a coffee stirrer.

Final Verdict

The Tomei Expreme Joint Pipe TB6060-SB03A is a high-quality exhaust upgrade for the Toyota 86, Scion FR-S, and Subaru BRZ. With its larger 60.5mm diameter, lightweight construction, SUS304 stainless steel materials, and complete installation package, it provides measurable improvements in exhaust flow while supporting future power modifications.

For FA20 enthusiasts looking to maximize the effectiveness of their exhaust setup, this is a proven upgrade that delivers both performance and durability.
