Dinan® Free Flow Exhaust for BMW 328i 323i E46
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. The Dinan exhaust
also provides substantial weight reduction compared to the stock
muffler, weighing in at just over 17 lbs., compared to the stock
system at 28 lbs. Dual 2.5 inch diameter polished stainless steel
exhaust tips give the cars a tasteful performance look as well.
