vrs xpipe

I just bought a set of bbk long tubes. but i was wondering whether or not i could use a vrs x pipe made for long tube headers for the bbk long tubes or are there specific ones for them? Or will the vrs only fit certain long tubes? Thanks for everyone's help in advance
 
yeah i do agree it does sound loud and nice. I just bought a set of bbk long tube headers and i just got a great deal on a vrs catted x pipe also. so im hoping that it will sound mean and loud. just hope its not too quiet lol
