I am looking for the best muffler/pipe for a YS 61 ST2 in a Vigor CS. I think I want a MP1, but if there is a better one I knew this would be the place to find it. I'm looking for a quiet one that gives good power.
I know I'm asking a lot aren't I?

Muffler for ys61

I have used a hatori SB1 with good luck on my x-cell ST which will fit the vigor. YS61 engines don't work well with a MP1.

Thanks

I knew that some one would FINALLY answer my question. Why doesn't the MP work on the YS ?

I think the reason no one answered was
because they were all waiting to see
if you'd use the SEARCH feature and
see if possibly, this question/issue has
been talked about before.

By design. IMO, the regulated fuel delivery system of the YS61 is very sensitive to load, rpm and the return exhaust pulses that a tuned pipe or MP1. The SB1 on either the YS-61 or OS61 on cp30% is a plug-n-play setup.

MP1

I'm wondering the same thing. I just want a good exhaust system for the YS. What is wrong with using the MP1 on the YS?

MP 1 on a YS 61

I posted that question to Curtis and I got this in reply:

Question # 358 New!!
Curtis,
Is it ok to use your MP 1 on the YS 61? I know you designed it for the OS 61 WC, but will it provide the same kind of performance on the YS ?

Answer
The MP1 does not work well with the YS 61. The aggressive pipe tuning of the original MP tended to cause the YS 61 to richen excessively in the midrange. The MP1 creates great power with the YS61 it is just hard to get it to run consistent. The MP2 series though works very well with the YS engines.

We will soon release (around MAY 2003) a new MP2 60/70 pipe with should work very well with the YS 61.

So that answers that I guess...

ST2

Galifrey,
That's all he sent me, but I would assume that he meant the ST2, since it's the only one available .

Muffler

I just ordered a Hatori SB-14 from Rick's for it. Jason Krause says they make UNBELIEVABLE power with the 61. Call Nathan, he has one on his and loves it

Just to let you know, spent most of saturday trying to tune the YS61 on the MP and it was a hopeless case... wish I had read this before buying

anyway, Have a swap organised for a zimmerman ys muffler which should be fine...

I've got a Performance Specialties muffler that works great on the YS 61 for sale if anybody wants it. $65 shipped. It was designed by Dave Shadel, the YS importer in the U.S. for the YS80 but makes great power on the 61.
