Yes, I searched....

So, I would like to understand whats essentially different:

1) Is it the rubber hangers?
2) Is it some sort of bracket issue?

Why I am asking:

I have a 03 AP1. I am thinkig about getting a to get a 04 AP2 spugen exhaust and would like to know how I can get it to fit on my AP1.

Anyone else done this?

Thanks!
