Invidia N2 Cat-Back Exhaust System – 2013–2021 Subaru BRZ / Scion FR-S / Toyota 86 (ZN6/ZC6) | 60mm | Polished Stainless Tips | FA20

Upgrade the exhaust note and flow of your 2013–2021 Subaru BRZ, Scion FR-S, or Toyota 86 with the Invidia N2 cat-back exhaust — a 60mm stainless steel cat-back system with 101mm polished stainless tips engineered specifically for the ZN6/ZC6 FA20 platform. The N2’s single-layer construction delivers a more aggressive, louder exhaust note than dual-layer designs — bringing out the FA20 boxer’s distinctive character with a deeper, sportier tone at all RPM ranges. Direct bolt-on replacement for the factory cat-back with no cutting, welding, or modifications required.

N2 vs. Q300 – Which Invidia Cat-Back Is Right for You?

Invidia offers two popular cat-back options for the ZN6/ZC6 platform:

• N2 (this system): Single-layer pipe construction — louder, more aggressive exhaust note. Best for enthusiasts who want maximum sound presence and an aggressive character on the street and track
• Q300: Dual-layer pipe construction — quieter, more refined tone with reduced interior drone. Better suited for daily drivers who want an exhaust upgrade without the volume of a single-layer system

Key Features

• Single-Layer Construction – Aggressive Exhaust Note: Single-layer pipe construction produces a louder, more aggressive exhaust note compared to dual-layer designs — the N2 is noticeably louder than stock at all RPM ranges, with a deeper, sportier tone under acceleration and at WOT. Cold starts will be louder than stock. Suited for enthusiasts who want maximum sound presence
• 60mm Mandrel-Bent Stainless Steel Piping: 60mm (2.36") mandrel-bent stainless steel piping throughout — larger than the factory system, reducing back pressure and improving exhaust flow. Mandrel bending maintains consistent internal diameter through each bend, eliminating the restriction that occurs with crush-bent piping
• 101mm Polished Stainless Tips: 101mm (4") polished stainless steel exhaust tips — a clean, high-quality finish that fills the ZN6/ZC6 rear bumper cutouts for a purposeful, finished appearance
• Cat-Back – Emissions Friendly: Cat-back system replaces the exhaust from the catalytic converters rearward — factory catalytic converters are retained, making this system emissions-friendly in most jurisdictions. Verify local regulations before purchasing
• Direct Bolt-On – 2013–2021 ZN6/ZC6 FA20: Engineered as a direct-fit replacement for the factory cat-back on the 2013–2021 Subaru BRZ (ZC6), Scion FR-S (ZN6), and Toyota 86 (ZN6). Uses factory mounting points and includes all necessary gaskets and hardware. No cutting, welding, or modifications required
• Invidia Quality: Manufactured by Invidia — a respected Japanese exhaust manufacturer known for high-quality stainless steel exhaust systems for JDM and performance applications worldwide
