Description

IMPORTANT NOTICE: Will not fit models equipped with rear M-Tech bumpers.

Dinan offers a wide range of exhaust upgrades for imports like BMW, Audi, and Volkswagen. Their free flow stainless exhaust systems are precision-engineered for optimum power gains—with a civilized, sporty exhaust note that's appropriately aggressive at wide-open throttle. Plus, there's no irritating low-rpm "drone" that is common with so many other aftermarket mufflers. These free flow systems are manufactured from stainless steel, inside and out, for maximum resistance to corrosion and reduced weight (by 30 percent). They utilize the OE brackets and hangers for mounting in factory-like fashion. Order the Dinan free flow stainless exhaust system designed for your vehicle application.
