Dinan Valved Cat-Back Exhaust – Toyota Supra A90/A91
OVERVIEW
Evoke passion and excitement with the Dinan Valved Cat-Back Exhaust for the GR Supra. Utilizing factory cut points and mounting mechanics, this is a straightforward, precision-fit install — but that's where the similarities to the factory exhaust end. Fabricated from brushed 100% T304 stainless steel, TIG welded, and free of hydroformed pipe, the Dinan system abandons the stock single-to-dual pipe layout for an enlarged, free-flowing single pipe design that feeds a drone-abating muffler tuned for the signature deep, rich Dinan tone. Gases exit through massive dual 4.5" straight-cut tips laser engraved with the Dinan logo. Factory valve control is fully retained, so you can keep it civil for early mornings or open it up for a full-throttle symphony — sound without sacrifice, in one refined package.
