Dinan sport mufflers are designed to compliment the M3 and not overpower the driver and passengers with harsh tones. Dinan engineers their exhausts to sound great and be a natural fit to the character of the car as well as produce more power and torque. Four 3.5" black ceramic tips engraved with the Dinan logo fill out the rear valence (choose either polished or satin black tips). Annoying highway drone has also been engineered out of the system. Dinan uses only 304 stainless steel in their systems for the maximum corrosion protection. This system replaces the factory rear mufflers at a pre-determined cut point on the stock exhaust, which makes for an easy installation and you can reinstall your original mufflers using factory hardware. Detailed installation instructions are included.

Features of the F9X M3 Dinan Exhaust -

  • Single channel design
  • Sportier Sound
  • 10 lbs lighter than stock part + 100% 304 stainless steel construction
  • Simple installation using high quality BMW OEM clamps and hangers
  • Quad 3" laser engraved black ceramic coated exhaust tips with Dinan logo
  • 6 HP & 5 lb-ft of torque
  • "Straight Through" canister design
  • Helmholtz chamber to remove drone

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. This setup is worth 3 point towards your Dinan badge.
