Will a 05 wr450 exhaust fit my 99 wr400?

14 posts in this topic

You can likely make it fit - I believe on the slip on silencer the bolt does not line up perfectly with the subframe mount - anything 03 and older fits the 99's without modification

i have a 05 wr muffler on my 03 wr 450. It fit perfectly without any modifications. Before that I had an 02 wr426 muffler on my 99 wr400. I think that it will work without any mods.

Really? I tried lining up my 07 muffler on my 99, and with the cannister bolted on (rear) the mid-pipe bolt hole does not line up with the bolt hole in the lower sub frame (about 2 inches apart) and the mouth of the mid-pipe stops about 2 inches short of the FMF head pipe on the bike :busted:

well let me just say that i just got the bike and i havent realy torn into it at all there are a coupple of things i need to take care of before i would ride it but the guy i got it from told me that the muffler was off of a 07 mind you this guy reused alot of worthless parts and bubblegummed alot of things togather so i will have to look at "how" he made it work and if its anything like everything he did to the bike its half assed but the exhaust is solid and looks clean and no leaks so i guess i shouldnt complain about that

My guess would be that he used some kind of bracket to attach the cannister to the rear mounting point on the upper sub-frame. Peek under the right side number plate and see if the cannister mounting hole is lined up exactly over the sub-frame bolt hole, or is there is some kind of bracket/adapter being used.

I put an 04' (Canadian) exh on my 99 400, all I had to do was slightly elongate the rear mounting hole on the can to line up with the sub frame.. took about 30seconds with a drill bit :busted:

ok fyi i just bought a white brother e sires exhaust off an 03 wr 450 and bolted right on to my 98 wr 400 used the stock header due to the damaged white brothers header but had no problems bolting it right on took about 5 minuets may need to adjust exhaust or jetting but sounds way better
