Remus 904019 1500 Sport Axle-Back Exhaust System with Integrated Valve

The Remus 904019 1500 is a centered sport axle-back exhaust system designed for the Toyota GR Supra equipped with the 3.0L turbocharged inline-six B58B30C engine with Gasoline Particulate Filter (GPF). Handcrafted in Austria from premium stainless steel, this performance exhaust system delivers the signature deep, sonorous Remus tone while improving exhaust flow and throttle response.

Key Features:

• Centered L/R axle-back design with one integrated valve for dynamic sound control
• Valve activation via OEM electronics — uses the original actuator through the vehicle's onboard system, no additional hardware required
• Matching tube diameter — original Ø 70 mm / Remus Ø 70 mm for seamless integration
• EC type approval included — street-legal in applicable markets
• No rear skirt modifications required for a clean, factory-look installation
• 100% stainless steel construction for long-lasting corrosion and heat resistance
• Weight-optimized design reduces overall exhaust system mass
• Performance and torque increase over the factory exhaust setup
• Robotic MIG/TIG welds for superior strength and durability
• Handmade in Austria to OEM-level tolerances

Important Installation Notes:

• The original exhaust system must be cut during installation
• This part number covers the sport exhaust muffler only — tail pipes are sold separately (compatible options: Remus 0426 80SA chromed or 0426 80SAB Black Chrome stainless steel tail pipe sets, Ø 115 mm angled)
