You think the reatta FSM is large, the one I have for my '98 park avenue ultra is easily twice that of the reatta.
They take a little getting used to, but once you do, it's not that bad. I usually consult the how to section of this site first though and go to the FSM if I need more info.
How about this one. I also had a '66 corvette convertible which had a removable plate on the standard under body dual exhaust pipes........modified for racing with an open exhaust. Crazy fun.......
"Corvette had factory side pipes" - chambered exhaust was quieter than Hooker side pipes if you left the inserts out. Tried stuffing with steel wool but all blew out at the top of second.
If she's like my wife she probably thought it could be done in 30 minutes or less because she saw someone do it on HGTV. Also, if she's like my wife she is all for it until the work starts and then she disappears. 🙂
I find the FSM very well laid out and easy to use. It just takes a while to get use to it. I carry mine in one of the compartments behind the seat for side of the road use if needed.
