Dinan Free Flow Axle-Back Exhaust for BMW | E46 | 325i/330i

Dinan's Free Flow Exhaust for the 3 series models provides increased flow for power gains without the excessive noise associated with typical ''performance'' mufflers. The Dinan exhausts feature rigid and durable muffler cases manufactured from 20 gauge 304-stainless steel for optimum corrosion resistance. Internally, the systems feature Dinan's Tuned Resonance Chamber technology which provides the optimum balance between maximum power gains and a civilized, yet sporty exhaust note.

Dual 2.5 inch diameter polished stainless steel exhaust tips give the cars a tasteful performance look as well.
