This axle-back exhaust complements Active Autowerke€™s full X3M/X4M exhaust lineup, which includes a single mid-pipe and GESI catted downpipes, enabling a comprehensive upgrade that maximizes sound and exhaust flow. While this axle-back section provides a noticeable enhancement over stock, the most dramatic sound improvements occur when combined with their mid-pipe and downpipe components.
Note: A version of this rear exhaust is available for customers opting to retain their stock mid-pipes; however, additional parts or charges may apply if upgrading to an Active Autowerke mid-pipe later due to required connections.
This product balances performance and auditory appeal, reflecting Active Autowerke€™s commitment to refined, authentic M-car driving dynamics.
