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

The Dinan Free Flow Axle-Back Exhaust (D660-3950) is a truly high-performance solution for the 2000-2003 BMW M5, designed to effectively reduce back-pressure for improved flow and the resulting power gains, without the excessive noise associated with typical aftermarket mufflers. This unique system is manufactured from 20 gauge-304 stainless steel inside and out for optimum resistance to corrosion.

Internally, the system features Dinan's Tuned Resonance Chamber Technology, which provides the optimum balance between maximum power gains and a civilized, yet sporty exhaust note. The system provides a verified power increase of +6 HP and +5 LB-FT of torque at 6500 RPM (when used with software) and achieves a substantial 28 lbs. weight reduction compared to the stock 66 lbs. muffler (actual system weight is 37.6 lbs.).
