I just bought a 2010 R/T Classic with 6 speed. Looking at putting a K&N cold air and Force II exhaust with resonators. I don't want the cab drone so I guess the Force II is my choice for the money. American Thunder, drone level anyone? I would like loud exterior but don't want to gain the interior. Is K&N the choice on cold air kits? Any help would be good, just wanna let it breath better without spending a ton of money. Help.
