The stock over pipe is not only narrow, it also has flattened sections which severely limits the performance gains from fitting a high efficiency manifold. However, our new pipe has its sections welded together to maintain a wide 63mm diameter throughout with additional weld beads on the inside for rigidity.
O.D. : 63mm I.D. : 60.6mm (stock 57mm with crunch bend)
Pipe Thickness: 1.2mm

**The T1R over pipe for GR86/BRZ is not the same as GT86 / BRZ so please order according to the model of your car.**
