Description
The stock exhaust not on the X5/6M is already a glorious note but Dinan gave you even more control with this valved axle-back system. With enlarged pipes letting the 8-cylinder engine breathe better, showing up to +6hp! The valve system lets you dial back the tone of the exhaust when needs be but lets you unleash the S63's voice when you so desire. The system uses the OE valve system so they can be controlled through the M-driving settings through the cars onboard system so there is no need for an additional remote. All in all this axle-back system is a great upgrade to your beloved X5/6M!
