Description

MSV Racing 304 Stainless Steel ’85-’01 CR500 “HORSEPOWER” Exhaust Manifold—Our Premium Manifold Built for Strength & Performance!

If you’re looking for an exhaust manifold that delivers unmatched durability, increased power, and superior fitment, the MSV Racing 304 Stainless Steel CR500 “HORSEPOWER” Exhaust Manifold is the perfect upgrade. Engineered for maximum reliability, these manifolds are identical to the dyno-proven, performance-enhancing hard anodized aluminum manifolds, but are made with tougher, more resilient 304 stainless steel.

Unleash More Power from Your CR500!

🚀 Dyno-Proven Gains

  • Expect up to +3.9 HP and +1.4 lb-ft of torque, depending on your engine build.
  • Designed to optimize exhaust flow, ensuring stronger power delivery and improved throttle response.

🔥 Premium 304 Stainless Steel Construction

  • This material far exceeds OEM quality, providing increased durability, longevity and a bullet proof design.
  • Unlike inferior manifolds that can warp or degrade over time, this stainless steel manifold is built to last and look amazing over the long haul.

More Benefits That Set It Apart

High-Temp FKM O-Ring Seal for Leak-Free Operation

  • Prevents the dreaded black drool issue commonly found with OEM flanges.
  • Allows for easy pipe removal and installation without needing to re-seal, saving time and hassle.

⚙️ Innovative 4th O-Ring for Gasket-Free Maintenance

  • Eliminates the need for a separate gasket, meaning no scraping or replacing during top-end work.

🚀 Optimized Exhaust Port Design for More Power

  • Features a .500″ lead-in taper on the flange side, allowing for larger exhaust port matching and potential horsepower gains.

💎 Sleek & Aggressive Aesthetic

  • Precision-crafted for a premium look that enhances your CR500’s appearance as well as its performance.

Upgrade to the Best CR500 Exhaust Manifold Available!

Many aftermarket manifolds fail due to poor materials, subpar fitment, and weak customer support. MSV Racing’s stainless steel manifold eliminates those concerns, providing top-tier performance, maximum reliability, and effortless installation.
