  • Turbo Manifold

    Turbo Manifolds / Race Manifolds – Maximum Turbo Performance for Motorsports

    Our turbo manifolds are specifically engineered for motorsport use, ensuring optimal exhaust gas flow to the turbocharger. Flow-optimized runners, as equal-length as possible, and high-grade materials such as stainless steel or Inconel provide maximum exhaust energy, enabling faster spool, higher boost levels, and maximum power output.

    Whether for drift, time attack, rally, or circuit racing – our race manifolds offer significantly increased durability compared to OEM units and withstand extreme temperature and pressure loads under competitive conditions.

    With precise manufacturing and motorsport-focused design, our turbo manifolds enhance exhaust gas dynamics, reduce backpressure, and increase the efficiency of the entire turbo system. Perfect for drivers who want to unlock the full potential of their turbocharger – with no compromises in performance or reliability.

  • Downpipes

    Downpipes – Maximum Exhaust Flow for More Power

    Our downpipes greatly enhance exhaust flow, allowing the turbocharger to spool faster and operate more efficiently. With larger diameter tubing and optimized flow design, exhaust backpressure is significantly reduced, resulting in noticeable power gains, quicker throttle response, and lower exhaust gas temperatures.

    Built from high-quality stainless steel and engineered with durable welding techniques, our downpipes withstand extreme temperatures and pressures, even during extended track use. They provide long-term reliability while reducing stress on the turbocharger and the entire exhaust system.

    Whether for performance tuning or professional motorsport, an upgraded downpipe is one of the most effective ways to increase turbo system efficiency. Improved gas velocity, faster boost buildup, and a substantial performance boost make it an essential upgrade for demanding drivers.

    Available for a wide range of vehicles, our downpipes can be seamlessly integrated into existing exhaust setups depending on the configuration. Perfect for anyone looking to unlock the full potential of their turbocharged engine without compromising quality or durability.

  • Wastegate

  • Exhaust Band Clamp

    Exhaust Band Clamp – Secure, Leak-Free Exhaust Connections

    Our exhaust band clamps provide an extremely reliable, leak-free and vibration-resistant connection between exhaust components. The wide clamping surface distributes the force evenly, reduces stress on the tubing, and effectively prevents leaks in the exhaust system.

    Manufactured from high-quality stainless steel, these clamps are corrosion-resistant, heat-resistant and perfectly suited for high-performance exhaust systems – from OEM setups to tuned street cars and full motorsport applications.

    Benefits of a band clamp:

    • Secure & sealed connection: Prevents exhaust leaks and withstands high temperatures.
    • Wide clamping area: Gentle load distribution and reduced material stress.
    • Vibration-resistant: Stays firmly in place even under heavy load.
    • Easy installation: Quick to fit, no welding or major modifications required.
    • Universal use: Suitable for various pipe diameters and exhaust layouts.

    Perfect for joining downpipes, mid-pipes, mufflers and connector pipes – a durable, clean and professional solution for any exhaust system.
