Collection: Exhaust Downpipes

Downpipes — Korsh

High-flow downpipes engineered for Subaru WRX, STI, and Honda Civic performance applications. Whether you're building for the street or the track, Korsh downpipes are designed to reduce backpressure, improve turbo spool, and unlock the power your engine is capable of — in both catted and catless configurations.

Subaru Applications

• EJ20 / EJ25 — Catted & Catless Downpipes
  Direct-fit downpipes for the classic EJ-series turbocharged Subaru platform. Catted options retain emissions compliance while delivering improved flow; catless options are suited to full-build and motorsport applications where maximum performance is the priority.
• FA20 / FA24 — J-Pipe
  Purpose-built J-pipe replacements for the FA-series Subaru platform (WRX VA/VB). Designed to improve exhaust flow from the turbo outlet and complement supporting modifications on the newer generation WRX.

Honda Civic Applications

• FK8 / FL5 Honda Civic Type R — Catted & Catless Downpipes
  High-flow downpipes for the K20C1-powered Civic Type R. Catted options use a high-flow sports cat to reduce restriction while maintaining a level of emissions compliance; catless options are designed for track and competition builds seeking maximum exhaust flow.

All Korsh downpipes are bolt-on fitment using OEM flanges and mounting points. No cutting or fabrication required. We strongly recommend pairing any downpipe upgrade with an ECU retune to fully realise the performance gains.

Catless downpipes are intended for off-road and motorsport use only. Lead times vary — contact us for current stock availability and ETA on specific fitments.
