I'm selling a Dinan Free Flow Exhaust recently removed from my '02 E39 540i non M-Tech The exhaust is in very good condition as shown in the pictures. It provides a deep throaty sound at open throttle but is nowhere near obnoxiously loud compared to other "performance" mufflers.

The exhaust features a 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, providing 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, 18.5 lbs vs 34 lbs. Dual 3-inch diameter polished stainless steel exhaust tips give the cars a tasteful performance look as well. This is an axle-back exhaust. Gain +7HP/+6TQ.

$540 OBO. Local pick-up in SoCal welcomed. Shipping at buyer's expense. Thanks for looking.
