I was looking for an OEM style exhaust that eliminated the extra plumbing under the bike, which the stock system had. I decided to make the change now, while the various rubber parts on the exhaust were still new and supple. Everything went together well and if you like the look of the stock pipe, this system looks even better. It's slightly louder than the stock unit and I included some pictures of my bike with the new exhaust along with a short video (another Monkey owner) describing the system, as well.

If you're looking for a louder or different style exhaust... keep searching.

The reason the stock headpipe winds around under the engine is that long head pipes produce more low rpm torque. The short head pipe of the Takagawa exhaust is for more high rpm horsepower which is what most riders want.

Hy, I installed the same Takegawa on my Monkey and like the result very much.
  • Idle - not louder at all
  • Ride - crisp sound, a bit louder but not loud. Just right
  • More clearance
  • Less weight
  • Cleaner look
@tooter , I read that more often that loss of torque should be one of the results in such a setup. For what exact technical reason do you think it should be like that? If it was a 2-stroke engine, I would agree with you.

But since it is a 4-stroke and the manifold has the same diameter, the exhaust gas velocity should remain the same and that is IMHO the important detail, not the backpressure. More backpressure reduces power from the engine since it has to work against that resistance.

Personally, I cannot feel a big difference in torque when riding the Monkey with the Takegawa.

Would really be interested in the technical details behind and finally ... the truth, if we're able to find it :)

regards, f r e d

I personally did not, for the bike was new when I made the changeover.

As you mentioned; stock appearance, plus additional ground clearance. Now I can use my go-to motorcycle jack for regular maintenance.

Now what's needed is a heavy-duty skid plate that will fit with this exhaust. I have the KITACO unit but it's more for use with the "cat" and will require minor surgery to clear the head pipe so I'm going to just send down the road. I have a big slab of 1/4" aluminum so I guess I'll build my own.

I'll echo what everyone else said about the slight increase in noise and how perfectly it fit. It also has no packing to replace. Getting rid of the snake-that-swallowed-a-rat pipe gives you a LOT more ground clearance, too.

Be warned when installing the headerpipe - the Takegawa flange is half the thickness of the stock Honda unit and made of soft steel. Do not use the Honda (20ftlbs) or even the Takegawa (22nm) torque specs. You'll end up bending the flange and your header bolts. Nice product other than the cheap flange.
