    Honda 400ex Muffler - works great, had to cut a little length off of the head pipe for it to fit correctly but you are talking about a 20+ year old machine with lots of bent and broken parts. Great buy if you are handy and have some basic mechanical ability.

  • Not a perfect fit

    Bolt holes don’t seem to line up right. Alignment is wrong and there is a problem with the mounting points flushing out with the frame of the bike. If I cut some length off my existing head pipe, it probably will work but I wish it just bolted up.

  • Great Muffler..

    Honda EX 400 Great option over OEM. Bolt holes do line up correctly. However the header pipe needs to be trimmed a half inch where it slips into the muffler. the welds inside won't allow it to slip in all the way wich causes the lower bolt hole to be off. A quick trim of a half inch with the saws all and bingo. Great fit.

  • Horibbke fit!

    The flanges and the holes for the bolts were off by over a half inch so I had to drill new holes which barely made it onto the upper flange. I would have returned it but it’s for my daughters 400ex and we needed it with a spark arrestor for a planned weekend ride. I would suggest spending the extra money for a new oem muffler.

  • Buy oem

    Cheap quality, does not fit. Would take modifications to bolts or to stock header pipe. Get oem
