Dinan 08-11 BMW M3 (E90) Free Flow Axleback Exhaust System - Black Tips

The single-channel dual exhaust is a full 10 lbs lighter than the stock BMW part. The Dinan Free Flow Axle-Back Exhaust is a sporty sounding exhaust at wide-open throttle when you want it but also quite and civilized when you are at light throttle cruise. This is consistent with Dinan's core philosophy of "Performance Without Sacrifice". One of the reasons you purchased your BMW is because of its level of refinement. You won't ruin the refined characteristics of your BMW when you use Dinan performance products. This level of development takes time and is the reason Dinan is usually not the first company on the market but you will find it is worth the wait.
