Show original supplier description
The HKS LEGAMAX Premium exhaust system, part number 31021-AT006, is designed for the GR YARIS GXPA16 with the G16E-GTS engine, covering model years from September 2020 to March 2024. Constructed from S304 stainless steel, it features 101.6mm dual tips and a dual center pipe measuring φ70 – φ54 x 2. While providing a comfortable exhaust volume for daily driving, it delivers a distinct, dry sporty sound when accelerating. The newly designed black tail tips are ion-plated for excellent corrosion and weather resistance, featuring HKS laser engraving. It's important to note specific fitment exclusions. This exhaust is not compatible with the RS (1.5L FF) grade, vehicles with a GR rear bumper spoiler, or the GRMN YARIS (which does not comply with Japanese car inspection regulations). Additionally, it is not compatible with models made after March 2024. The RC-grade vehicle with standard 17-inch tires does comply with Japanese car inspection regulations.
