Hi guys,

 

If my question is asked before, i am sorry.

But I didn't find any proper answer on internet.

 

I ride CRF450X for few years, Yamaha is a new for me. I bought a 2004 YZ450F for couple hundred bucks. Seller had no idea what was wrong with the bike. Its engine was locked.

 

Now I know its problems and started top end rebuild.

 

My question addresses a header pipe and muffler fit.

 

It doesn't have header pipe, seller told me that he lost it.

 

So please give me proper and practical infos.

Which years' header pipe will fit?

Which models? (WR and etc)

'03 -'05 are direct replacements.  The '06 may fit, but not too well.  WR headers are the wrong size.

thanx for the answer.

 

as my search result, many says that 2007-2009 also manageable to fit there. what do you think?

The '07-'09 will have a different outlet diameter, so you'd have to change the muffler as well to match.  Besides, the '08-'09 system is a poor performer.
