Description

Invidia Part Number: HS22TGCFPCEA3L

The Invidia catted front pipe for the Toyota GR Corolla is a performance exhaust upgrade designed to improve exhaust flow, enhance turbo response, and support higher power levels while retaining a catalytic converter for street-focused builds.

On many platforms, this section of the exhaust is commonly referred to as a midpipe. Positioned between the downpipe and the cat-back exhaust, the front pipe (or midpipe) plays a critical role in overall exhaust efficiency and sound character. The factory GR Corolla front pipe can become restrictive as power levels increase, especially when paired with aftermarket downpipes or cat-back systems. The Invidia front pipe replaces the OEM section with larger-diameter piping and a high-flow catalytic converter, helping the turbocharged G16E-GTS engine operate more efficiently.

This upgrade is ideal for GR Corolla owners who want improved exhaust flow and performance while maintaining a catalytic converter in the exhaust system.

What the Front Pipe (Midpipe) Does on the GR Corolla

The GR Corolla exhaust system is made up of multiple sections:

• Downpipe (closest to the turbocharger)

• Front pipe / midpipe (center section of the exhaust)

• Cat-back exhaust (rear section)

While many upgrades focus on the downpipe or cat-back, the front pipe—often called the midpipe—is an important supporting component. Improving this section helps reduce backpressure and smooth exhaust flow throughout the entire system.

Benefits of upgrading the front pipe / midpipe include:

• Improved exhaust flow and reduced restriction

• Faster turbo spool and smoother power delivery

• More consistent performance under load

• Enhanced exhaust tone when paired with aftermarket systems

Engineering and Construction

The Invidia GR Corolla catted front pipe is engineered for performance, durability, and precise fitment.

Key design features:

• 76 mm (3.0-inch) mandrel-bent exhaust piping

• High-flow catalytic converter

• TIG-welded stainless steel construction

• Direct bolt-on fitment using factory mounting points

• Designed specifically for the GR Corolla AWD platform

The larger-diameter piping and optimized flow path help reduce turbulence and exhaust restriction, making this front pipe (midpipe) an ideal complement to aftermarket downpipes and cat-back exhaust systems.

Performance Characteristics

While a front pipe or midpipe alone does not dramatically increase horsepower, it plays an important supporting role in performance-focused GR Corolla builds.

When combined with other exhaust upgrades, benefits can include:

• Improved turbo efficiency

• More responsive throttle feel

• Enhanced exhaust sound character

• Increased performance potential with tuning

This makes the Invidia front pipe a logical upgrade for enthusiasts building a balanced exhaust system rather than focusing on a single component.

Fitment

• Toyota GR Corolla (2023+)

• Engine: 1.6L Turbo G16E-GTS

• AWD drivetrain

Designed as a direct bolt-on replacement for the factory front pipe / midpipe.

Frequently Asked Questions

What is the difference between a front pipe and a midpipe?
On many vehicles, these terms are used interchangeably. On the GR Corolla, the front pipe refers to the section between the downpipe and cat-back exhaust, which many enthusiasts also call the midpipe.

Is this front pipe street legal?
This version includes a catalytic converter, which makes it more suitable for street-focused builds, though emissions legality depends on local regulations.

Will this front pipe increase horsepower?
On its own, gains are modest, but it significantly improves overall exhaust flow when combined with other upgrades.

Will this cause a check engine light?
Because this front pipe retains a catalytic converter, it is less likely to trigger a CEL compared to catless exhaust components, though results may vary depending on tuning and vehicle configuration.

Does this fit with aftermarket exhaust systems?
Yes. It is designed to work with stock and most aftermarket downpipes and cat-back exhaust systems.
