little hint. id never done headers on a 3800 before i did mine 3,000 miles ago. its like no tools either, i did it all with a 30 piece socket set, a 13 mm ratcheting box wrench, ( highly recommended) and a breaker bar with a 18 mm for the rear sub frame bolts, two jack stands and a floor jack. every how to i read said to take the TB off, i didnt even do that, there was enough room with a few extensions to get them bolts off.
and a angle grinder lol only one bolt snapped it was a cross over bolt, so its best to break them, vs strip them if you know what i mean.
my car also had 230,000 miles on it at the time of install.
