HKS Hi-Power Toyota/Subaru FA20 Spec-L2 Single Exhaust

The HKS Hi-Power Spec-L2 exhaust system features a 75mm piping diameter, a substantial increase over stock, designed to improve exhaust flow for the FA20 engine found in many Toyota and Subaru models. This larger diameter helps reduce backpressure, allowing the engine to breathe more freely and potentially unlock more power. The system is constructed from SUS304 stainless steel, a well-known material for its strength and resistance to corrosion, ensuring it holds up well over time even in harsh conditions.

This is a single-exit cat-back system, meaning it replaces the factory exhaust from the catalytic converter back. The Spec-L2 designation points to HKS's focus on a refined sound profile, aiming for a sportier tone without being overly aggressive or droney. The muffler and piping are carefully shaped to optimize sound and performance. Installation involves bolting onto the existing catalytic converter outlet and routing the new piping and muffler assembly to the rear of the vehicle. While it's a direct-fit system, some adjustments may be needed to align the exhaust perfectly.

Included with the exhaust are all the necessary hangers, gaskets, and hardware for installation. This system is a popular choice for owners looking to enhance the sound and performance of their FA20-powered vehicle. It’s a well-built component that reflects HKS's long history in performance exhaust manufacturing.
