Which way do I go?

There's more than one?

There's 4, and 4 spin off movies also.

What?! 4?! No there are 8 american pies!
American Pie (1999)
American Pie 2 (2001)
American Pie - The Wedding (2003)
American Pie - Band Camp (2005)
American Pie - Naked Mile (2006)
American Pie - Beta House (2007)
American Pie - Book of Love (2009)
American Pie - american reunion (2012)

Thats 7 too many

If you actually read my comment properly you would have seen that I said there are 4 movies in the series and 4 spin offs ( the spin offs being Band camp to Book of love).

I think it's the deleted scenes from the fourth movie
