CP-E QKspl Downpipe, Catted – 2023-2026 Toyota GR Corolla

Description:

The cp-e High Flow Cat Quick Spool Downpipe for the GR Corolla is a complete bolt-on, turnkey solution for more power out of the stock turbocharger.

We replace the stock unit with a massive turbine matched cast bellmouth and full 3-inch diameter tubing all the way to the factory cat-back system. Our unit is full 304 stainless steel construction with the finest TIG welds and components.

Tuning is not required to install this downpipe.

Our GRC Downpipe is designed and built with rugged construction to withstand your performance and spirited driving. Your GRC downpipe will arrive to you with a full proprietary Titan finish.

We also take the necessary design steps to keep the check engine light from coming on. OEM exhaust hangers and a large Euro-style flex section create an OEM style quality installation.

Our first step is to 3D scan the OEM downpipe and design our new setup using the latest in 3D CAD software. We overlay our new design with the OEM to make sure you have a perfect fit.

Our main design point of our downpipes are our cast 304 stainless steel bellmouths. Using 3D scanning and computer modeling, we can match the turbine outlet geometry while maximizing the air flow as it necks down into the tubing. This allows us to make tight bend geometry while maintaining a nice and thick-walled part that can withstand the abuse of racing both on the track and auto-cross. This technique is far-superior to pie-cut, welded tubing in every way!
