Help required re fitting aftermarket air filter

Hi guys I have a 2008 800 intruder with the oval rugby ball shaped air box. I have found an air filter which you remove the standard air box to fit but I am going to need to extend the rubber part of the air intake manifold down and round like a j shaped extension, is there anything out there that could accomplish this.
