Free Flow Exhaust (E39) 528 Sedan non M-Tech

Special Note: Not applicable for wagon or cars equipped with rear M-Tech bumper.

Product Description
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. The Dinan exhaust also provides substantial weight reduction. Dual 2.25 inch diameter polished stainless steel exhaust tips give the cars a tasteful performance look as well.

Dinan's Free Flow Exhaust for the 528 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.

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