This Roush Mustang EcoBoost Resonator Delete Y-Pipe gives your S550 some more volume for a sportier sound. This is a great way to make driving your Mustang more exciting, as the stock exhaust system keeps the 2.3L engine pretty quiet. 

Better sound. Roush gives your Mustang some more volume and a sportier sound with this Y-pipe. The 2.25-inch pipe offers a deeper sound that is nice at idle or under acceleration. 

Minimized restriction. The Y-pipe helps give your exhaust system an even flow. The 2.25-inch mandrel bent pip improves the exhaust flow. This is a great benefit for turbocharged cars like the EcoBoost, and the improved exhaust flow should help to spool the turbo sooner, provide better response, and reduce backpressure.
