Need Rough Lengths For Custom Exhaust

[ForT5calibaKilla]

I have a 94 suburban and I have recently looked into a custom exhaust sytem. The problem I have been havin is no one has exactly what Im lookin for. Luckily I found a great combo of aftermarket parts that would give me a true dual exhaust with dual cats and headers and the best part is the muffler set up will alow me to go from my 3 inch x pipe to 2 single/dual mufflers and then I can put 4 magnaflow dual tips on each 2 1/4. That gives the effect that I have 8 exhaust pipes. Its really a great setup all I really was wondering if anyone had had the time to maybe figure out what the over all maximum length of the exhaust system can be. I just need rough figures since im buying through an internet after-market parts store. I would get down there and measure myself except I seem to be lacking the time and energy, and was kinda hopin one of yall might have a custom exhaust or the length written down somwhere. Any help or comments would be much appriciated.
