Toyota GR Corolla Downpipe – High-Flow Catted & Catless

Unlock better turbo response and exhaust flow with the GGP Toyota GR Corolla Downpipe. Designed for the 2023+ Toyota GR Corolla equipped with the 1.6L G16E-GTS turbo engine, this downpipe is built for owners who want a more responsive, freer-flowing exhaust setup.

The factory downpipe is one of the most restrictive sections in the GR Corolla exhaust system. Upgrading to a performance downpipe helps reduce restriction after the turbo, allowing exhaust gases to leave more efficiently. The result is quicker turbo spool, improved throttle response, stronger midrange feel, and a more aggressive exhaust tone.

Available in both high-flow catted and catless options, this downpipe gives you the flexibility to choose the setup that best matches your build, goals, and intended use.

Why Upgrade?

Improves exhaust flow after the turbo

Helps reduce backpressure

Supports quicker turbo spool

Can improve throttle response and midrange power feel

Enhances exhaust sound

Great supporting upgrade for tuned GR Corolla builds

Available in high-flow catted and catless configurations

High-Flow Catted Option

The high-flow catted version is the better choice for customers who want improved exhaust flow while keeping a catalytic converter in the system. This is the more balanced option for street-driven builds, customers who want a cleaner setup, and owners who want a performance upgrade without going fully catless.

Catless Option

The catless version is designed for customers who want maximum exhaust flow and the least restriction possible. This option is best suited for off-road, race, and track-use builds where emissions compliance is not required.

Built from stainless steel for strength, heat resistance, and long-term durability, this downpipe is designed to handle the heat and abuse of a turbocharged performance setup.
