Invidia Up-Pipe – Subaru Models (Inc. 2006-2014 Subaru WRX / 2004-2021 STI)

Up-Pipe for Subaru WRX, STI, and EJ Models

The Invidia Up-Pipe for Subaru EJ-series models replaces the factory up-pipe with EGT bung. The factory Subaru up-pipe flex section fatigues over time, developing cracks that create boost leaks and exhaust leaks. The Invidia stainless replacement eliminates this failure mode and includes a bung for EGT sensor installation.

DETAILS

• 304 stainless steel construction
• Replaces factory up-pipe
• Eliminates flex section failure
• Includes EGT bung

The Invidia up-pipe with EGT bung is the correct specification for builds that use an EGT sensor at the up-pipe position, common in tuned Subaru builds where monitoring exhaust gas temperature before the turbocharger is part of the engine management strategy.

Replacing the up-pipe on a high-mileage EJ Subaru is one of the most impactful reliability modifications available. The factory flex section failure is a when, not an if, on cars with significant mileage.

Why Choose Invidia

Invidia has been manufacturing performance exhaust systems in Japan since 1999, and in that time they have built a reputation that carries real weight in the tuning community. Every system is manufactured using SUS304 stainless steel and mandrel-bent tubing, which eliminates the flow restrictions and weak points that crush-bent alternatives introduce at every corner. Their in-house engineering team designs each application from scratch rather than adapting a generic template, which is why Invidia fitment is consistently tighter than the competition. The result is an exhaust that installs cleanly, seals correctly, and lasts. Invidia backs their products with a quality standard that is visible in the finish, the weld quality, and the hardware, details that reflect over two decades of refining the same core manufacturing process.
