Scott,
Your exhaust system is laid out pretty much like mine, only yours appears to have been done nicer. Were you thinking of adding additional brackets to hold the pipes up? I'd have to look at mine again. I haven't been under the car in some time, aside from bolting and unbolting my bumpers.
I also like the pipes exiting behind the rear wheels. Although it does look good exiting out below the bumper. But I hear wagons are more susceptible to exhaust fumes entering thru the rear hatch of the car.
My exhaust system was done more than 20 yrs ago, believe it or not. When I lived in NY, most shops at the time did not want to do duals. I think it had something to do with compliance at the time. No catalytic converters, plus not being able to pass inspection.
They did the bologna cut at the ends, but I added tips to exit out further past the body.
Wow!! Your car looked very much like mine, especially with the SS air dam...and being all white. My last paint job was a Maaco special. It looked pretty good for a number of years until the paint started flaking and going dead. I also had a few rust areas that needed attention...including my doors, fenders, rad support.
