Description
The HKS LEGAMAX Sports Exhaust provides an application-specific exhaust configuration. Application: 2021 Subaru WRX.
Design and operation
Pipe diameter, routing and silencer construction influence exhaust flow, sound and clearance. The useful comparison is the complete configuration: a rear-section assembly and a system that includes center piping do not replace the same factory components.
Technical details
- Manufacturer part number: 31021-AF026.
- Application: 2021 Subaru WRX.
- Exhaust outlet specification: 98 x 4 mm.
- Main-pipe specification: 74.7 - 60.5 x 2 - 45 x 4 mm; this does not describe every section of the system.
Application-specific requirements
- Power check (Exhaust replacement only).
Installation and selection
Match the chassis, engine, body style and supplied exhaust sections to the vehicle. Check compatibility with existing headers, front pipes and catalytic converters. Ground clearance must be assessed at the vehicle’s actual ride height.
