This Milltek Sport catted downpipe fits the Toyota GR Corolla with the 1.6 liter turbo three-cylinder and the 6-speed manual, from the 2023 to 2026 model years. It replaces the factory turbo downpipe with a 76.2 mm (3.0 in) large-bore pipe, and it replaces the factory secondary catalytic converter with a section carrying a 200-cell high-flow sport cat.
The downpipe is the most restrictive part of a small turbo engine's exhaust, so this is where a tuned GR Corolla gains the most. Milltek recommends an ECU tune to get the full benefit, and it marks this part as race/track only.
It is made in England from mandrel-bent T304L stainless steel and fits the factory mounting points.
There are two versions, and the right one depends on the exhaust behind it. For Milltek Secondary Cat-Back (SSXTY154) comes with a link pipe that joins a Milltek secondary cat-back system. For Factory Cat-Back (SSXTY153) comes with an adapter that joins the original Toyota exhaust. Neither fits a Milltek primary cat-back, which already replaces this section.
If you are buying both parts, the Milltek GR Corolla cat-back exhaust page also offers this downpipe as an add-on to its secondary cat-back systems.
