The Invidia N1 Single Exit Cat-Back Exhaust is built for VB WRX owners who want aggressive sound, improved exhaust flow, and a lighter, more performance-focused rear-end setup. Made from T304 stainless steel, this single-exit system uses 76mm mandrel-bent piping and a cannon-style muffler to reduce restriction and give the FA24 a much more serious exhaust note.

Designed with performance in mind from start to finish, the N1 exhaust route is carefully shaped to minimize unnecessary bends and turbulence. The result is a freer-flowing cat-back that supports improved throttle response, reduced back pressure, and a louder, more aggressive tone compared to the factory exhaust.

Key Features

• Single Exit N1 Layout: Lightweight, aggressive, and motorsport-inspired design for the VB WRX.
• 76mm / 3.0" Piping: Large-diameter piping helps improve exhaust flow and reduce restriction.
• T304 Stainless Steel Construction: Durable stainless construction helps reduce the risk of cracks, breaks, rasp, and vibration.
• 1.5mm Thick Mandrel-Bent Piping: Smooth bends help maintain consistent exhaust flow with minimal turbulence.
• Cannon-Style Muffler: Classic Invidia N1 sound and appearance with optimal flow and minimal back pressure.
• 101mm / 4.3" Exhaust Tip: Large single tip gives the rear of the WRX a more aggressive look.
• Titanium or Stainless Steel Tip Options: Choose the finish that best matches your build.
• CNC-Machined Flanges: Precision fitment and long-term durability.
• Robotic Welds: Consistent weld quality for strength and clean appearance.

Why We Like It

The N1 Single Exit is the Invidia exhaust for VB WRX owners who want the car to sound and feel more aggressive. The single-exit layout cuts visual clutter, gives the rear a more purpose-built look, and delivers a sharper tone than a more reserved dual or quad-tip setup. If you want something louder, simpler, and more performance-focused, this is the one.

Sound & Performance

Invidia designs the N1 exhaust system around a smoother exhaust path with minimal bends, helping exhaust gases exit with less restriction. This can improve exhaust flow, throttle response, and overall driving feel while adding the aggressive sound profile the N1 lineup is known for.

Compatibility & Disclaimers

Designed for 2022–2026 Subaru WRX applications. Exhaust sound, fitment, and performance results may vary depending on J-pipe, tuning, and other supporting modifications. Single-exit exhaust systems may leave the opposite factory exhaust opening unused. Always verify local noise and emissions regulations before installation.
