Description
Borla ATAK Cat-Back Exhaust is built for 2023–2026 Toyota GR Corolla. This version uses polished tips. The tubing layout is 3" Into 4) 2.25" Tail Pipes.
Sound and Engineering
ATAK tuning gives the exhaust an assertive character under load. Its acoustic design shapes tone and manages resonance; overall volume still depends on the engine and the rest of the exhaust.
An active exhaust valve is included in the assembly. Follow the actuator and wiring instructions to retain the documented valve operation.
Polyphonic Harmonizer passages use different lengths and diameters to develop multiple exhaust notes before the mufflers shape the final character.
Mandrel-bent tubing maintains its cross-section through bends, keeping the intended pipe shape through changes in direction.
