I'm not totally sure because I haven't tried it, but when I talked to Buschur they didn't think it would work either, but they are willing to let you order it and if it doesn't fit you can return it. Just want you to know what might happen so your not disappointed.

I guess someone with the Buschur upper IC and Filter is going to have to take off their MAS pipe and filter and see if the stock box will work with the Upper IC. Sounds like a little project....eh, SAEVO?

Yep, let me go check right now by just eye-balling it. I can get a no or maybe answer.

ummm, well its a definate maybe. Remember that you will also need to get a smaller battery. I will get a better answer about the stock air box and BR I/C pipe on Sunday.

Kool thanks for looking!
