Dinan Free Flow Exhaust for BMW M5 E39 2000-2003

Product Description

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.

*Dyno results for the combination of Stage 2 Engine Software; Cold Air Intake and Free Flow Exhaust.
