Remus 900121 9999 Racing GPF-Back Outlet Tube Set Dual Flow

The Remus 900121 9999 is the Racing Dual Flow Outlet Tube Set, a required component of the Remus Racing GPF-Back System engineered for the Toyota GR Yaris (Type XPA1G, G16E engine with GPF). This outlet tube set pairs with the front section replacement tube (900121 1300) and the Racing Sport exhaust (900121 1500) to complete the full GPF-back system assembly.

Key Features:

• Dual flow outlet design for optimized exhaust gas scavenging and improved flow efficiency
• Upgraded tube diameter of Ø 70 mm over the stock Ø 65 mm for reduced backpressure
• Installs at OEM serial mounting points — no rear skirt modifications required
• 100% stainless steel construction manufactured in Austria
• Compatible with the full range of Remus tail pipe sets (sold separately)
• Designed to work exclusively with Remus GPF-back components 900121 1300 and 900121 1500

As a racing product, this outlet tube set carries no ECE/EEC type approval and is intended for closed-course motorsport use only. Use on public roads is not permitted under EC regulations. ECU remapping is recommended when fitting this system to optimize exhaust performance and prevent check engine lamp activation.

ATTENTION: This part must be used in combination with Remus front section replacement tube 900121 1300 and Racing Sport exhaust centered unit 900121 1500. The original exhaust must be cut during installation.
