Manifold madness

Just had the Stillen big Break kit installed on front of My 2004 4x4 so far so good will keep you posted, main reason for thread is while at the dealer I also wanted them to cheak out what sounded like another exaust leak comming from engine compartment. had the drivers side exaust manifold replaced under warranty at 52000, then the other side at 73000,now the truck has 116500 GUESS WHAT?...dealer informed me passenger side manifold is cracked AGAIN and if studs need replaced will cost $1300.00 to replace.:crying: Like the breaks I ha looked for an after market solution but have only found headers? any ideas?
