exhaust pipe size and routing opinions?

[samwise68]

i'm getting ready to buy pipe for my exhaust. it'll be on a stock 307, aside from headers. i already purchased glasspacks to use, however they're 2" in/out. (i hope that won't be a problem.)

so, i'm wondering how you might reccommend i stage down the exhaust pipe from collectors to the tail pipe? how about tips?

and how you personally would run your home brew exhaust pipe?

i appreciate any and all input...thanks in advance!
