Remus 045019 0500LR 047017 0000 0046 83CTSR Axle-Back Exhaust System with Carbon Angle Tail Pipes

The Remus 045019 0500LR / 047017 0000 / 0046 83CTSR is a performance axle-back exhaust system featuring Φ84mm carbon angle tail pipes with titanium-lined interiors (style code 0046 83CTSR). Engineered by Remus in Austria, this system is designed for the Audi S4 (B9/8W) Avant 3.0 TFSI and upgrades the factory exhaust with a larger 70mm pipe diameter over the stock 60mm — reducing back pressure and delivering a more aggressive exhaust note.

Key Features:

• Upgraded 70mm pipe diameter — up from the OEM 60mm for reduced back pressure and improved flow
• Valve-controlled sound management — integrates with and reuses the factory OEM actuator system for quiet cruise and on-demand sport sound
• Φ84mm Carbon Angle tail pipes (0046 83CTSR) — dual carbon-finish angled tips with titanium-lined interiors
• 100% stainless steel construction — shot-blasted surface finish for long-lasting durability
• Handmade in Austria — precision-crafted for perfect fitment and form
• Lightweight design — engineered for minimal weight addition
• 24-month manufacturer warranty
• No vehicle modification required — direct bolt-on installation

What's Included:

• Center/muffler section (PN: 045019 0500LR)
• Replacement central section (PN: 047017 0000)
• Φ84mm Carbon Angle tail pipe set, left & right (PN: 0046 83CTSR)

This Remus exhaust system is compatible with vehicles without a Gasoline Particulate Filter (GPF) and cannot be installed on vehicles equipped with panoramic glass sunroofs. It delivers the signature Remus sport sound profile while maintaining OEM-level refinement during everyday driving.
