Description
The HKS Hi-Power SPEC-L II is a lightweight stainless-steel cat-back system for the EJ20-powered Subaru WRX STI (VAB, 2014-2020). It improves exhaust flow and throttle response while delivering a cleaner, more assertive note with minimal cabin drone, and is JASMA certified.
Features
- SUS304 stainless-steel construction for durability and corrosion resistance
- Hi-Power SPEC-L II layout with a dual-tip design and 65-50 mm centre pipes to reduce backpressure
- Sporty tone of about 89 dB versus roughly 78 dB stock at idle, tuned to limit drone
- Lightweight system at about 10.4 kg for a useful saving over the stock exhaust
- Maintains around 125 mm ground clearance
