Remus 4682 658013 Stainless Steel 2-into-1 Race Header Manifold

The Remus 4682 658013 is a high-performance stainless steel 2-into-1 exhaust header designed as a direct replacement for the factory manifold. Built for race use, this header eliminates the catalytic converter for unrestricted exhaust flow, helping to maximize power output and throttle response.

Constructed from premium-grade stainless steel, this race-spec manifold offers excellent durability and corrosion resistance while delivering the performance gains serious riders demand. The 2-into-1 design consolidates exhaust flow from both cylinders into a single optimized outlet, improving scavenging efficiency and contributing to gains in horsepower and torque across the rev range.

Key Features:

• Premium Stainless Steel Construction — Corrosion-resistant, built for long-term durability and high-heat performance
• 2-into-1 Header Design — Optimizes exhaust scavenging for improved power and torque delivery
• Race Homologation — Designed for race/track use; not street-legal (not homologated for road use)
• No Catalytic Converter — Replaces the OEM header with a free-flowing, cat-delete configuration
• Direct OEM Replacement Fitment — Engineered as a drop-in replacement for the stock manifold
• Not Compatible with KTM Powerparts Motor Protection — Verify accessory compatibility before installation
