Dinan Valved Cat-Back Exhaust for 2020-2026 Toyota GR Supra 3.0 - D660-0096

Give your 2020-2026 Toyota GR Supra 3.0 a deeper, louder exhaust note while retaining factory valve control with the Dinan D660-0096 Valved Cat-Back Exhaust. Designed for A90 and A91 GR Supra applications, this system is constructed from TIG-welded T304 stainless steel and features an enlarged 83mm primary exhaust path, a drone-reducing muffler, and dual 4.5-inch polished double-wall exhaust tips. Dinan reports maximum gains of 6 HP and 5 lb-ft of torque at 6,600 RPM while reducing exhaust-system weight by 10 pounds compared with stock.

The Dinan system replaces the factory single-to-dual pipe arrangement with an enlarged, freer-flowing single-pipe design and removes the factory resonator/collector for increased exhaust volume. Factory valve control is retained, allowing the system to provide maximum flow and a more aggressive sound with the valve open. When the valve is closed, exhaust gases are redirected through the muffler for a more subdued tone. Drone-abatement technology helps reduce unwanted cabin resonance while maintaining Dinan's deeper exhaust character.
