While only scenes, which had to be removed in order to receive an R-Rating, were added to the Unrated Version of the first part of the "American Pie"-franchise, the sequel already received scenes which probably weren´t cut for censorhip reasons from the theatrical version.

With 19 Differences the Unrated Version is totally 6:07 minutes longer.

Two guys from High School chew Stiflers ear off by telling him how much they appreciate being at the party because their own parties always get broken up by the police. But Stifler only distributed the flyers at High School to attract some girls but not these losers. When the boys want to know if it is true that Finch slept with Stifler´s mom, he throws them out.

41s

10th minute alternatively
Again alternative material because of continuity reasons. In the unrated version, Stifler still says something about the two boys, then the camera zooms back and we see Jim, Finch and Kevin saying that Stifler´s parties are still the same. The Rated-R-Version shows this remark from a different perspective.

When Oz arrives at the party, he is received immediately by Stifler who wants to know how he likes the steady relationship (with Heather) and wonders in a slightly reproachful tone what has become of the former Casanova. Oz thinks he was an idiot before. Then Stifler shouts to the crowd that Nova is back and that she puts away the chastity belt for them. Oz keeps cool, even when Stifler introduces a female friend to him and turns her down.

Vicky and Jessica cross the shop in different takes while Jessica explains the three-way-rule to Vicky; saying that when Kevin claims that there were three girls it really means that he only slept with one girl. In the unrated version the scene has a longer beginning because Jessica says at the start that Kevin´s successes are as probable as the Backstreet Boys wanting her as background singer.

In alternative shots Amber pulls down Danielle´s bra. The scene is relatively short in the theatrical version, however in the unrated version it runs longer. At first, Danielle hesitates at first and doesn´t let her friend pull down her bra. She doesn´t hesitate in the Rated-R-Version.

The scene in the hospital´s waiting rooms runs much longer. In the theatrical version, father and son sit there quietly, no one dares to say a word. At last, Jim´s father asks how he feels and Jim answers that he has been better before; then a cut to the treatment room.
In the Unrated Version, this scene lasts much longer. Instead of the akward silence, Jim´s dad explains the danger of adhesives and that they should have warnings on the package. But Jim answers that he mistook the tube for lubricant. Then a woman in a wheel chair notices the porn video which is still stuck at Jim´s hand and reproachfully asks him why he didn´t leave the video at home. Immediately Jim´s Dad intervenes and defends his son. He does this very aggressively. Without success Jim tries to calm him. Very loudly, Jim´s father tells everybody that Jim´s hand is stuck to his penis and imputes that the woman doesn´t have any sympathy for the situation because she lacks a penis.
