Product Description

Dinan's Free Flow Exhaust for the 540 provides 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.

The Dinan exhausts also provide substantial weight reduction compared to the stock mufflers. The mufflers weigh in at 18.5 lbs. compared to the stock systems at 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.

Dyno Results for Stage 2 Engine Software, Cold Air Intake and Free Flow Exhaust.
