Installation and Usage

Downpipe replacement on the A90 Supra requires good access underneath and some disassembly near the turbo outlet, so a professional performance workshop should handle the installation. Whether this part retains a catalytic converter has not been confirmed; if not, ECU calibration is generally required. Check sensor fitment, flange sealing and clearances once installed, and recheck fasteners after the first few heat cycles.
