Do you have to get the car tuned or tune out the cats if you just put long tubes to a cat back system

**HELP** Im about to put some headers on my G8 GT but about a week ago me and a friend were working on his Silverado putting headers on there and one of his bolts broke and now he's in that boat n got quoted $1500 to get the broken part removed so instead to save money he is just going to buy a new head but now we are super nervous about doing mine and having a bolt break lol so my question is how hard is it to remove those bolts?? Obviously without seeing it its kinda hard to say but to give you as much info as possible its a 09 with 150000 miles not driven to the ground but raced once in awhile and also most of all if you had any tips or tricks or magic spells/dances to have the best chance of not breaking a bolt??
