Yoshi pipe on stock 300ex?

[Ben]

I have an FMF Performax and FMF head pipe on my pretty much stock 300ex, and a K&N filter. I don't care for the looks of the Performax or the sound. I want to put a Yoshi slipon on my FMF headpipe. Will this cause any power gains? Should I get the complete Yoshi system? Money isn't a concern. Thanks.

you can't get a yoshi slip on and put it on w/ ur fmf header. The Yoshi is made for the stock header, which is smaller than the fmf, so you would have to buy the complete system or put the slip on on your stock header.

you can put the yoshi slip on on the wb header.. but that doesn't make much sence in this situation
