Dinan X5 and X6 M exhaust

The X5 and X6 M are monstrously quick and fun machines but there’s always room for improvement, especially when it comes to the soundtrack, which is where Dinan’s new performance exhaust system comes in.

This free-flowing system, made from 100% T304 stainless steel, reduces back pressure to boost power by 8hp and torque by 7lb ft but, more importantly, it gives the twin-turbo V8 a far more satisfying soundtrack, but one which Dinan says isn’t overly loud and drone is kept away thanks to a Helmholtz chamber. This means time in the car can be spent enjoying the V8 and not nursing a drone-induced headache.
