Dinan Stainless Steel - Polished Tip - w/ M-Technic Bumper - E39 D660-3946

Dinan's Free Flow Axle-Back Exhaust for the 540i equipped with the M-Technic bumper provides power gains without the excessive noise associated with typical ''performance'' mufflers.

Internally, the systems feature Dinan's Tuned Resonance Chamber Technology providing the optimum balance between maximum power gains and a civilized, yet sporty exhaust note. The Dinan exhausts also provide substantial weight reduction compared to the stock mufflers. The mufflers weigh in at 18.5 lbs. compared to the stock systems at 34 lbs. Single oval polished stainless steel exhaust tip give the cars a tasteful performance look as well.
