Special Note: This exhaust is for the Coupe only.
Dinan's Free Flow Exhaust provides increased flow for power gains without the excessive noise associated with typical ''performance'' mufflers.
- The Dinan exhaust features 3 1/2'' stainless steel polished and laser engraved tips. Using Rigid and durable muffler cases, Dinan exhausts are manufactured from 20 gauge 304-stainless steel for optimum corrosion resistance.
- The Dinan exhaust also provides substantial weight reduction compared to the stock muffler.
