3.0 or 2.5 ???
thanks
...????? you put a new engine in,and didnt do headers at the same time?...i dont understand..a 15 minute job vs a 6-8 hour job now..oh well,to your question...2.5" is more than enough...3 should only be used under extreme hp conditions 
not only 15 minutes job is the monetary problem i installed thge 3.0 about 6 months ago after that was the tranny rebuilded then a month later the alternator right now the slave cylinder from the trainy that the prlobem when i am decided to buy the headers or have the money something happens  i hope after this i will get the headers jejeje and the 2.5 exhaust changed
