2004 CRF450R Exhaust

I have a 2004 CRF450R, i bought a 04 header and a 2003 Silencer, im missing a mid pipe, would a stock 2003 mid pipe work? Thanks for all of the help!

no mid pipe on a 03?

There is no mid pipe. You must have FMF parts. I think FMF is the only one that runs a mid pipe.

Not sure then, are the 03 and 04 silencers different lengths?

the 03 stock header is longer than the 04 stock header , so the 03 muffler has a shorter SS section than the 04 muffler , you need a 03 header or a 04 muffler

Yeah no mid pip on the 03

the 03 stock header is longer than the 04 stock header , so the 03 muffler has a shorter SS section than the 04 muffler , you need a 03 header or a 04 muffler

what he said :thumbsup:

What other years of silencer or years of headers would work?

I think i will get an 02 header, since they are the same as the 03.

that will work :thumbsup:

So to clarify, putting a 2002 CRF450 header and a 2003 CRF450 Silencer on a 2004 will work?

i belive the exhausts from 02 to 04 are a little different each year. 02 and 04 are definatly different. not sure if 03 resembles one.
