sti downpipe upgrade for 2015-2020 wrx models

If you're looking to upgrade your STI downpipe for a 2015-2020 WRX model, you're in the right place. The STI downpipe upgrade is a great way to improve your car's performance.

The stock downpipe on your WRX is likely to be a restrictive bottleneck, especially when you're pushing your car to its limits. This is because the stock downpipe is designed for emissions and not for performance.

Upgrading to an STI downpipe can increase your car's power output by up to 20 horsepower, depending on the specific upgrade and your car's current setup. For example, the STI downpipe upgrade can add 15 horsepower to a Stage 1 tune, and 20 horsepower to a Stage 2 tune.

When working on an exhaust system, having the right tools is essential for a smooth and efficient job. A socket wrench is a must-have for any exhaust system project.

A 32mm socket is typically required for removing the exhaust manifold bolts, as mentioned in the "Components" section. This size is crucial to avoid stripping the bolts.

A torque wrench is necessary for tightening the exhaust system components to the recommended torque specifications, which can be found in the "Installation" section. This ensures the system is properly secured and prevents leaks.

A muffler clamp tool is also a handy tool to have, as it can be used to tighten the muffler clamps, which are responsible for securing the muffler to the exhaust system. This tool can be found in the "Components" section.

A set of gloves and safety glasses are essential for protecting yourself from hot exhaust components and flying debris, which can be a hazard during an exhaust system project.
