can I mount an FMF 4.1 RCT muffler for CRF250R-2011 on my CRF450R-2011

[Oldy]

Hi guys,

I've found a used FMF 4.1 RCT for CRF250R-2011 that is in perfect conditions and at a really good price. 

The problem is that my bike is a CRF450R-2011 and i'm wondering if i can put it on.

Anyone has some info for me? Someone has ever tried it out?

as you can see from the pics, it seems that only the beginning of the tube is different (47mm vs 50.5mm) and the OEM 450's header can mount both diameter.

If you see the pic the header has double flange, ext. 50mm and int. 43mm

what do you think about?

thanks in advance
