The S1-GP focuses on lightweight construction and a clean racing-inspired appearance. Its titanium body, end cap, and link pipe work together to create a consistent look that complements the aggressive character of the Z900.
100% Titanium Construction
The S1-GP follows a clear design philosophy: 100% titanium. The body, end cap, and link pipe all use titanium, helping the exhaust achieve a remarkably low weight.
The complete SC Project exhaust weighs only 1 kg, compared with 4.1 kg for the stock exhaust. Therefore, the S1-GP provides a claimed 3.1 kg weight reduction compared with the original exhaust.
Performance-Focused Exhaust
The S1-GP delivers a claimed +3.5 hp at 8200 rpm and +2.8 Nm of torque at 8200 rpm. These figures highlight the performance-focused character of this lightweight slip-on exhaust.
Moreover, its low overall weight gives the S1-GP a strong advantage for riders looking for a lightweight exhaust solution for their Kawasaki Z900.
Conical Body and Distinctive Sound
The sporty conical body works with the outlet diameter, special internal soundproofing, and internal dB-killer housing. Together, these elements create a full and satisfying sound for the Z900’s four-cylinder engine.
The system also includes a dB-killer, which sits within the dedicated internal housing. This helps maintain the approved configuration of the exhaust.
Carbon Heat Protection
The S1-GP comes with a large autoclave-made carbon protection. This component completely replaces the original protection and adds a distinctive carbon detail to the titanium exhaust assembly.
The carbon protection also complements the minimalist titanium body, creating a balanced combination of materials and finishes.
Street-Legal Euro 4 Approval
The S1-GP carries EC/ECE type approval and remains street legal under Euro 4 regulations. A type approval certificate also comes with the exhaust.
This makes the S1-GP suitable for riders who want a sporty and lightweight exhaust while retaining its approved road configuration.
Simple Slip-On Configuration
The S1-GP uses a slip-on design with bracket mounting. This provides a focused upgrade for the Kawasaki Z900 while keeping the exhaust package compact.
The titanium construction, internal soundproofing, dB-killer housing, and included carbon protection create a complete solution designed specifically around the Z900.
