Dinan D660-3950 Free Flow Axle-Back Exhaust - Compatible with 2000-2003 BMW M5

Dinan's Free Flow Exhaust for the M5 provides improved flow and the resulting power gains without the excessive noise associated with typical ''after-market'' mufflers. The Dinan exhaust features a rigid and durable muffler case, manufactured from 20 gauge-304 stainless steel for optimum resistance to corrosion. 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 system also reduces weight substantially, weighing in at only 37.6 lbs. as compared to the stock system at 66 lbs. Dual 3-inch diameter polished stainless tips give the cars a tasteful performance look as well. Fits: BMW; M Series; M5; Sedan; E39; 2000-2003.
