Invidia Front Pipe w/ High Flow EA300 CELL Cat - 2013-2017 Subaru BRZ / 2013-2016 Scion FR-S / 2017 Toyota 86

The Front Pipe: The FA20 NA Platform's Biggest Exhaust Restriction

The Invidia Front Pipe with High Flow EA300 CELL Cat for the 2013-2020 Scion FR-S / Subaru BRZ / Toyota 86 addresses the most significant exhaust restriction on the FA20 naturally aspirated platform. The factory front pipe between the exhaust manifold and the mid-pipe is small diameter and highly restrictive — replacing it with the Invidia unit and EA300 high-flow catalytic converter opens the exhaust flow path significantly while maintaining emissions compliance.

EA300 High-Flow Cat — Better Flow, Still Compliant

The EA300 CELL catalytic converter uses a higher-flow cell structure than the factory catalyst — less restriction at the same emissions function. For the FA20 naturally aspirated platform, the front pipe and cat combination is one of the most cost-effective exhaust upgrades available — the restriction it removes is directly upstream of the exhaust manifold, improving exhaust scavenging and mid-range throttle response throughout the rev range.

Bolt-In at OEM Front Pipe Location

The Invidia front pipe bolts directly to the factory exhaust manifold flange and mid-pipe connection on the FT86/BRZ. OEM O2 sensor bung positions are retained. New gaskets and hardware are included. No modification to the manifold or mid-pipe connections required.

Straight From Subispeed

The front pipe is the correct first exhaust upgrade on the FA20 FT86/BRZ — it is the largest single restriction in the exhaust path and the EA300 cat makes it possible to address that restriction without going catless. If you are building the FA20 naturally aspirated platform and have not done the front pipe yet, this is the purchase to make before anything further up the exhaust system.
