Berk Technology Round Overpipe with Wideband Bung — Scion FR-S / Toyota GT86 / GR86 / Subaru BRZ

Replace the restrictive factory oval overpipe on your FR-S, BRZ, or GT86/GR86 with the Berk Technology Round Overpipe — a properly round, free-flowing upgrade with a built-in wideband O2 bung for tuners who demand more from their build. A simple but effective upgrade that improves exhaust flow and opens the door for precise wideband tuning.

The factory oval overpipe is a known restriction in the FA20/FA24 exhaust system. Berk's round overpipe eliminates that bottleneck with a properly shaped round cross-section for improved flow, while the integrated wideband bung allows you to run an aftermarket wideband O2 sensor for accurate air/fuel ratio monitoring and precise tuning.
