Overview:
Dinan's Free Flow Axle-Back Exhaust for the M5 provides improved flow and the resulting power gains without the excessive noise associated with typical aftermarket 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.
Features:
- More Power: + 6 HP @ 6500 RPM + 5 LB-FT @ 6500 RPM (w/ software)
- Drone abatement technologies used to reduce cabin resonance

- Over 28 lbs. lighter than stock (37.6 lbs. vs. 34 lbs.)

FAQs
|Q. What is an Intermediate Brake Line?
