Description
Description
HKS designed the Super Turbo Muffler cat-back to deliver powerful performance with a quiet, comfortable sound: once you step on the pedal, a dry sporty exhaust note is heard throughout the cabin. A 75mm straight structure generates the lowest exhaust pressure possible while maintaining interior comfort, and the JASMA-standard sound suits street use without sacrificing performance.
- HKS part 31029-AF011 — the stainless-steel tip variant (dual silver tips, not the burnt-blue titanium tips of the Super Turbo Ti 31029-AF013V)
- Full SUS304 stainless steel construction
- 75mm main piping splitting to dual 60mm piping
- Two 124mm (4.9 in) polished stainless tips with owl-feather slot design to reduce exit sound
- Center pipe with resonator included
- Sound level: 85dB (stock 78dB); 60dB at idle for both
- Fits 2015-2021 Subaru WRX and WRX STI (VA chassis)
- Note: with a stock j-pipe/downpipe, the GrimmSpeed stock-DP-to-aftermarket-3in-catback adapter (p/n 077046) is required
