Hmf 400ex fits big red 250es?

[Mondexbrute]

I emailed HMF and asked them if they might make me an exhaust for my Big Red 250es and this is what they sent me...


Jeremy, we’ve been told by a few customers that the 400EX pipe fits with only a few small mods. I can’t confirm that because we haven’t tried it ourselves. Thanks

The muffler may, but I haven't tried it before. The headpipe is actually a 2 pipe into 1 like the 350X's. So it wouldn't work in that department. Anything will fit it if you cut and hack on it.

Did specify atc250es, as I believe this is a trx250es

[Mondexbrute]

Just muffler, not headpipe! & yes I did specify it was a 3wheeler!

[3wheeledjunkie]

What pipe were you looking at. I think the headpipe outlet is bigger on the 400ex then on the Big Red

[Mondexbrute]

Again I am reffering to the muffler only! I know the headpipe will not work! I wasn't looking at any pipe in particular, HMF said that they have been told that the 400ex HMF Muffler will fit a 250 Big Red.

I'm saying where the headpipe ends and goes into the muffler, might be bigger. Therefor your headpipe mightbe too small to seal with the muffler.

[Mondexbrute]

yeah Im sure the 400ex pipe is bigger there, I would have to have someone fab & weld somehing up! Im not sure what to.

I needed a muffler. Went to my local cycle scrapyard and bought a 450r muffler and had Meineke make me a piece to go between header and the new muffler... turned out nice
