Ok i have got a question.... on what exhaust size and muffler i should go with... i have a auto mechanics class in school and i have all the tools at my disposal to make me a custom exhaust for my 2.8l, i have purchased some high flow cats but tempted to sell and just gut my old ones. some input would be appreciated

 

custom magnaflow

 

so what exhaust size should I go with? i was thinking a 2.5 all the way...i heard i should go with a euro-type muffler, forgot what brand tho.
