I know, I know.... another "which piipe" thread...

After doing a few searches, and going through some of the 7000+ threads I found... Here we go again...

We may be building a TB117 for a street CRF application. Currently with the engine in a 108 configuration, we're running a Yosh. To me, visually, this pipe's header seems too small for a 117.

Your thoughts and recommendations would be very helpful...

Thanks...

That pipe will work fine as its stepped to a larger diameter all the way to the muffler and the muffler its self has a large core.

have tried three diff "big bore" pipes on my 117 and couldnt tell any difference between them. fmf 4.1, yosh and hmf.

As it's a street machine, maybe go by sound more than raw performance? : )
