I doubt there is one. Are you looking for quieter INSIDE the car or OUTSIDE? If inside, there are a number of insulation kits, sound deadening materials, and sparys/foams/gels which can be applied to the vehicle to aid in reducing cabin noise. It's gonna be expensive and heavy so there is a trade-off.
Can't really suggest anything to quiet the exhaust on the outside......maybe add another set of cats downstream of the current pair? Don't even know if that is possible and would probably affect performance for the worse. Hope this helps....

I think stock is the winner of the quietest award.
You might be able to go to muffler shop and get them to custom build something quieter.

About the only thing quieter is to turn the engine off. 
Haven't heard of anything that makes less noise.
