Yoshimura · RS-3 · Full System
The Yoshimura Oval Track Mod Lites Full Exhaust is an RS-3 Signature Series Exhaust System designed as a full system for GSX-R1000 and ZX-10R applications in oval track racing.
Constructed with 20 gauge 304 stainless steel and formed with mandrel bends, this system targets consistent flow and a race-ready layout. It also incorporates practical mounting details intended to accommodate engine and chassis movement and to simplify service. Refer to the fitment information and the installation PDF on the page for setup guidance and requirements.
Materials
This full system is crafted with 20 gauge 304 stainless steel to create a durable foundation intended to be adaptable for most shaft-driven oval track race car platforms. Mandrel-bent tubing helps maintain consistent tube diameter through each bend, supporting a clean, consistent exhaust path from the header through the system.
Engineering
Yoshimura builds this layout as a purge-welded 4 - 2 - 1 design with a Merge collector. The configuration is engineered to optimize exhaust flow and performance, pairing race-focused routing with construction details aimed at producing a precise, consistent assembly for demanding oval track use.
Installation
Designed with spring mounting, the system is engineered to enable engine and chassis flex while also allowing easier removal. A vibration dampening rubber insulated muffler clamp, plus an adjustable muffler mount, help support stable positioning and reduce the effects of vibration in race car chassis setups.
The system is described as applicable to 2005+ Suzuki GSX-R1000 engines, and it is also stated as applicable to 2007+ Kawasaki ZX-10R, extending its use to additional engine packages found in oval track builds.
Engineering
Core construction details include 20 gauge 304 stainless steel tubing and mandrel bends for consistent tube diameter throughout each radius. The exhaust uses purge-welded fabrication and a 4 - 2 - 1 layout with a Merge collector, and it also features machined exhaust port manifold flanges. Together, these elements reflect a system engineered around consistent routing, precise joining, and a focus on optimized exhaust flow and performance.
Installation
The system is designed for Joker, Edge, H&E, and Cheater chassis, with a note that other chassis configuration fitments may vary. Because oval track builds can differ, some modifications may be required due to chassis and engine mount variations.
