Toyota GR Corolla Downpipe – High-Flow Catted & Catless
The GGP Toyota GR Corolla Downpipe offers high-flow catted and catless configurations for the 1.6L G16E-GTS platform. Confirm the exact model year, market, transmission and exhaust connection with GGP before ordering.
The downpipe sits directly after the turbocharger, making it an important part of the exhaust path on a turbocharged setup. Changing this section can affect exhaust restriction, response and sound, but no product-specific measured horsepower or response gain is stated here.
This GGP downpipe is available in both high-flow catted and catless configurations so you can choose the setup that best matches how the car is used.
Catted vs. Catless
| Option | Best For | What to Expect |
|---|---|---|
| High-Flow Catted | Builds requiring a catted configuration, after fitment and use are confirmed | Retains a 200-cell catalytic converter in the replacement assembly, confirmed by GGP. Application-specific road-use approval must be verified separately. |
| Catless | Only applications and uses legally permitting a catless configuration | No catalytic converter. Not recommended for road vehicles; a competition-use label is not a blanket legal exemption. |

Tuning, CEL & Installation
Discuss the exact hardware and calibration with a qualified installer or calibrator. A check-engine light may occur depending on the vehicle, calibration and downpipe configuration, so a CEL-free result is not guaranteed.
Professional installation is recommended. Confirm required hardware, gaskets, clearances and the applicable road-use requirements. A catalytic converter or tuning change does not by itself establish legal compliance.
