For those craving more, pairing it with the iE ProCore Downpipe takes volume to extreme levels—great for track use but overwhelming for most on the street. This optional Sport Muffler strikes the perfect balance, adding more sound than the catback alone while toning down the full turboback setup to a street-friendly level for everyday driving.\nJUST RIGHT\nDialing in the perfect exhaust note can be tedious, involving small changes to find just the right balance. Lucky for you, we have eliminated all the guesswork so you can achieve the exact balance you're after.\n\n\n\n\nCATBACK\nDOWNPIPE\nRESONATOR\nVOLUME\n\n\nSTOCK\nSTOCK\nSTOCK\nBORING\n\n\niE CATBACK\nSTOCK\nN/A\nLOUD\n\n\niE CATBACK\niE DOWNPIPE\niE RESONATOR\nROWDY\n\n\niE CATBACK\niE DOWNPIPE\nN/A\nINSANE\n\n\n\n\n\nBOLT-IN INSTALL\nThe iE sport muffler option replaces a straight section of the iE MK8 GTI Catback and includes the necessary clamps for a direct drop-in installation.
