i was wandering what size( length ) and type of pipes ill need to make dual exhaust from an 80 series flowmaster? im planning on using 2.5in pipe and stainless steel tips. Rock on man.........

 

Since nobody seems to have a response to your post I thought maybe I could give you something...

I needed 2 tailpipes for my Magnaflow muffler so I bought (2) 16 guage, stainless steel, 90 degree mandrel pipes (both the A & B legs were 15 inch) and then cut them to length. The leg that extended to the bumper came up fairly short but worked out perfect because my square chrome tips are 11 inches long. If your tips are shorter you will need your legs to be longer (17" or 18" or more). Buy them a little long and cut them down!
