I'll second that on Six Pack Performance, nice guys and real nice installation kit. besides good luck finding a mopar performance kit anywhere until another batch are made.
Sunny, if you shop around you can buy everything you need to put a six pack set up on a 440 for about $1850 all brand new. it looks real sweet but until I get to drive it I can't tell you if it was worth it or not, I don't care if I get any more power I just hope it's not a pain in the butt.
