The Cor Performance 14344 is a 3.0-inch exhaust downpipe engineered for the 2015-2017 Ford Mustang EcoBoost Fastback models equipped with the 2.3T engine. This component features a high-flow 200-cell catalytic converter within a race-inspired, straight-through design, aiming to maximize exhaust flow and overall vehicle performance. It is designed to integrate with a 3.0-inch cat-back exhaust system and includes an adapter for this purpose. It is explicitly stated that a tune is required for proper operation. The product comes with a Limited Lifetime Warranty for the downpipe itself, and a 1-year warranty specifically for the catalytic converter. It is important to note that this downpipe "Fits to 3.0 Inch Cat-Back, not Stock." For those seeking a stock adapter, Corsa Part Number 14351 is available separately.
