Holy crap I got a good scare tonight when installing the headers... I removed the old ones and realized that I needed some flanges for the Akrapovics but didn't know where they were! I looked around for a while and found them deep inside the box of foam peanuts thank goodness! That was scary thinking I would have to make some myself!
It can be done but would just take MORE time.
Just for reference this exhaust system is for a 2001 Akrapovic exhaust for the Aprilia Mille. I'm sure it will work on the 2000.5 although a lot of people talk about the 01 and newer frame/chassis being a tad shorter. That's why I'm putting it on now... I gotta make sure it fits so I'll be ready to ride once the rest of my parts come in.
