I have a 2007 CRF450R My buddy has a Big Gun EVO limited black ceramic pipe for a 2005. Think I can make the slipon fit my header?? He's out of state so I can't compare. If the subframe bolt and length work I think I can make it happen. So Jaws and ~ put your noggins together and let me know what ya think!! Mike

I knew I could depend on you! I did that first I talked to Mike Young (owner) and they spit them out as per spec and can't cross reference.(go figure).But he did say 06-07 were same but could'nt say same for 05-07 So I thought I'd see if we had a member with an 05 and a 07 to see if I got an easy awnser. Thanks for your reply!! Mike

The 05 R can will fit the 450X any year.

The 06 and 07 can will not.

Therefore the 05 can will not fit the other years of R otherwise they'd be interchangable as well.

The bolt holes do not line up. If you have access to a Heliarc (TIG) welder you could just cut it off and reweld it where it needs to be.

Thanks ~ thats what I was looking for! I have TIG at work but pipe is ceramic coated so I didn't want to grind it off. Mike @ Big Gun said they will make me one so I guess I'll go that route. How did you and Jaws get so smart did you go to different schools together!! Thanks for your input! MotoMike P.S. Bike is about done TCR wheels & Hubs,Sidewinder,AVS,Hamerhead,RBR Racing,CV4 Hoses SoCal DeCal....... will Upload pics soon as I figure that out!!
