armed with my new exhuast system, new parts from NAPA (thanks guys) and a lot of hand cleaner, I'm ready to bolt the sucker on. question is, is there any good references for the layout, or should I just start piecing the puzzle together? I have separate pipes for reducer, collector extension, into the muffler, out of the muffler, and tailpipe.
(ugh, i just talked to the very helpful guy at ground up, he mentioned the 'flattened' part where the crossmember is located.
my pipes are not flatten. am i screwed?)

nah, you're not screwed, there is a lot of room down there. i had the 2.5" flowmaster kit, the pipes were not flattened and they fit fine. better of with unflattened pipes anyway, less flow restriction. as for a plan of attack, the directions that came with my flows said to put the tailpipes in (it helps a lot if you have the car supported by the frame and the rear end is hanging), then attatch the tailpipes and mufflers to the rear hangers, then due the engine pipes. worked fine for me. good luck.

A couple of thoughts.
- Be prepared to take a lot of time fitting parts (it took me several trys to get 3 chamber Flowmasters into my '69 Elky)
- Take a look at the Factory Assembly Manual to bet a general idea how the parts go together and what critical clearances are.(see N10 option and UPC 8 A1-A10)
- Don't cut pipes or clamp tightly until you're sure that you've got a good fit.
- When working with the rear axle hanging down, it's easy to position the pipe kick-up over the axle so that it hits the axle tube on bumps. Check twice, cut/clamp once.

another tip to go along with Fred's advice: when trying out things , use duct tape at the joints to hold it in place until you are satisfied with the fit. It is easy to undo duct tape more so than a clamped-tight pipe.

One more tip (based on my experience):

Don't assume you can measure one side and then cut pipe for both sides. My hedders required different lenghts of pipe.

I started from the back and worked forward, which seemed to work pretty good.

The 2.5 inch exhaust is great! Have fun.
