Review STI

The STI SCCA STI-3100 is a high-performance aftermarket exhaust system designed for Subaru Impreza and WRX models with a STI heritage. This exhaust system is the result of Subaru Tecnica International's (STI) collaboration with SCCA (Sports Car Club of America) to create an exhaust system that delivers improved performance and a more engaging driving experience.

The STI-3100 is a full cat-back exhaust system, which means it replaces the rear sections of the stock exhaust from the catalytic converters back. It features high-flow catalytic converters that are designed to reduce backpressure and increase exhaust flow, leading to improved engine performance. The system also includes a high-performance muffler that provides an aggressive yet refined exhaust note.

The STI-3100 is made of premium T304 stainless steel, which is known for its strength, durability, and corrosion resistance. The system's mandrel bending ensures that it maintains a consistent diameter throughout, allowing for maximum exhaust flow and horsepower gains. The exhaust tips are made of polished SUS304 stainless steel and feature the STI logo.

The STI-3100 comes with all necessary hardware for installation, including exhaust clamps and gaskets. It is designed to fit Subaru Impreza and WRX models with a STI heritage, including the WRX STI and Impreza WRX STI. Installation is relatively straightforward and can be done by an experienced DIYer or by a professional exhaust shop.

In terms of performance, the STI-3100 exhaust system delivers impressive gains in both horsepower and torque. Depending on the specific engine and modifications, horsepower gains can range from 5 to 15 horsepower, while torque gains can range from 5 to 15 ft-lb. These gains translate to improved acceleration and a more responsive engine.

Overall, the STI SCCA STI-3100 is an excellent choice for Subaru Impreza and WRX owners who are looking to enhance their driving experience with improved performance and an aggressive exhaust note. Its high-quality construction, easy installation, and impressive performance gains make it a worthwhile investment for any Subaru enthusiast.

1. Powerful Engine: The STI-3100 comes with a 2.5-liter turbocharged boxer engine that produces 310 horsepower and 290 lb-ft of torque. This makes it one of the most powerful and fastest production Subarus ever.

3. Limited Availability: Due to its limited production, the STI-3100 may be difficult to find and purchase new.
