Overview

The Perrin PSP-EXT-120 is an overpipe designed for the 2013+ Subaru BRZ and 2013+ Scion FR-S.

This overpipe features a smooth and unrestrictive exhaust path, utilizing smooth bends and larger diameter tubing to increase flow. It is constructed from 2.5", 304 stainless steel with precision TIG welding. The CNC mandrel bent tubing ensures smooth airflow for maximum horsepower, unlike the factory 2.118" tubing with its sharp bends.
Show original supplier description
The Perrin overpipe serves as an essential upgrade for optimized exhaust flow, replacing the restrictive factory 2.118-inch tubing. By utilizing larger 2.5-inch diameter 304 stainless steel tubing with CNC mandrel-bent construction, this component eliminates the sharp, crimped bends found in the stock system, allowing for improved exhaust scavenging and maximum horsepower gains. Precision is maintained throughout the assembly with TIG welding and CNC-machined 1/2-inch thick stainless steel flanges. These flanges are counterbored on the inside to ensure perfectly smooth transitions when paired with a compatible Perrin header or front pipe. The kit includes two OEM exhaust gaskets to ensure a reliable seal during installation. This overpipe is designed for 2012-2016 Scion FR-S and 2012-2020 Subaru BRZ models. Please note that this product is intended for off-road use only and is legal in California exclusively for racing vehicles that are never operated on public highways. It is recommended that installation be performed by a professional experienced with automotive exhaust systems.
