Invidia HS15STIGM4SB Gemini R400 Cat-Back Exhaust Quad Black Tips

The Invidia Gemini R400 Cat-Back Exhaust System delivers exceptional performance and a rich exhaust note for enthusiasts seeking an aggressive upgrade. This single-layer exhaust features a design that combines minimal bends with larger diameter piping to allow unobstructed exhaust flow with reduced restriction and turbulence under acceleration.

Key Features:

• SUS304 stainless steel construction with fully polished finish for outstanding durability and corrosion resistance
• 76mm (3-inch) mandrel-bent piping diameter with 1.5mm wall thickness reduces back pressure and turbulence
• Four 101mm (4-inch) slash-cut quad black tips for an aggressive appearance
• Tuned resonated mufflers with continuous piping design and Advantex material for optimized back pressure
• CNC-machined cast flanges provide precision fitment and durability
• Robot TIG-welded construction ensures uniform strength and appearance
• Exhaust hangers welded at OEM locations for direct bolt-on fitment

Performance Benefits:

• Increased horsepower and torque gains through improved exhaust flow
• Enhanced throttle response and reduced turbo lag
• Deep, rich exhaust tone without excessive cabin noise or harsh rasp at highway speeds
• Designed to fill the sound gap between the Q300 and N1 exhaust systems

The Gemini R400 replaces all exhaust piping from the catalytic converter back, including muffler sections, mid-pipes, resonators, and connector pipes. All necessary gaskets and hardware are included for installation. Note that vehicles with stock downpipes may require a 3-inch adapter for proper fitment.
