Review GRIMMSPEED Exhaust Valve Simulator

The Grimmspeed Exhaust Valve Simulator (part number 070044) is an innovative performance accessory designed specifically for Subaru WRX and STI models with a catalytic converter. This device mimics the functionality of an exhaust gas recirculation (EGR) valve, providing a solution for those seeking to eliminate the unwanted characteristics of the factory EGR system without the need for expensive and complex aftermarket EGR deletion kits.

The Grimmspeed Exhaust Valve Simulator is a solid-state electronic component that plugs directly into the factory EGR valve harness, bypassing the EGR valve mechanism while still providing the necessary electrical signal to the engine control module. This allows for the elimination of the EGR valve and associated components, including the EGR cooler and associated plumbing, resulting in a cleaner and simpler engine bay.

The primary benefits of the Grimmspeed Exhaust Valve Simulator include improved engine performance and efficiency, reduced engine backpressure, and the elimination of the associated EGR-related issues such as carbon build-up and potential for engine damage. Additionally, the device is designed to be completely reversible, meaning it can be easily removed and reinstalled if desired, making it an excellent choice for those seeking a flexible and non-permanent modification.

The Grimmspeed Exhaust Valve Simulator is crafted from high-quality materials and is engineered to provide reliable and consistent performance. It is designed to work seamlessly with the factory engine management system, ensuring that it does not cause any issues or error codes. The device is also backed by Grimmspeed's excellent customer support and warranty, providing peace of mind for those looking to enhance their Subaru's performance.

In summary, the Grimmspeed Exhaust Valve Simulator (part number 070044) is an effective and easy-to-install solution for those seeking to eliminate the factory EGR system and its associated issues from their Subaru WRX or STI. With its solid-state design, easy installation, and reversible nature, it offers a flexible and efficient way to enhance engine performance and improve overall driving experience.

Grimmspeed Exhaust Valve Simulator (Part Number: 070044) is a popular aftermarket product designed to improve the performance of Subaru WRX and STI vehicles by simulating the effects of an exhaust gas recirculation (EGR) delete without actually removing the EGR system. Here are some potential pros and cons of this product:

1. Increased Power: By simulating the EGR delete, the Grimmspeed Exhaust Valve Simulator can help increase horsepower and torque, providing a noticeable improvement in engine performance.
