well....put my whole mac exhaust on...and my was that hell...i was not expecting it to be that difficult...me and two buddys started on it at 10 in the morning saturday..didnt get done till 2 in the morning sunday...and all of your arms are very sore...drivers side header was a b**ch..passanger side went right in...and the mac h pipe didnt fit well either..had to be perswaded

cat back went on good though..i was thinken..well at least no prob with cat back..then i find out that im missing one of those rubber hanger thingys..so the drivers side tail pipe is just wired up for now...sounds killer though
