These downpipes for the improve power, torque, turbo efficiency, and make the engine louder. The Wagner Tuning downpipes flow better than stock and other designs. These are some of the best fitting downpipes we have seen to date. The Wagner DP increases power by eliminating restrictions in the stock pipes. Reducing back pressure makes the turbo more efficient and longer-lasting while minimizing the potential for fault codes and limp modes when on track. With less back pressure the turbo can spool up faster and be more responsive - more boost is available sooner and with less lag.
