2025 Toyota GR-FOUR Yaris (MT) Downpipe Modification

A Unified Solution for MT & AT:
Through precise 3D spatial scanning, we confirmed that the automatic transmission (AT) downpipe bracket cannot be shared with manual transmission (MT) models due to clearance differences.

Today's Finding:
After scanning both the factory MT bracket and the engine bay space, we verified that a single universal bracket won't provide the perfect fitment we demand.

Next Step (Important Update!):
Rather than forcing a compromise, we are officially merging TY-GRCY05DP and TY-GRCY06DP into a single unified product package. Moving forward, every downpipe kit will include both MT and AT brackets so customers can seamlessly install it regardless of their transmission type. The separate part numbers are now history!
