I know pipes have been covered extensively here, and Ive gone back and read them.
But now that aftermarket exhaust is very limited for the 9er, I only see Yoshis out there new.
Anyone have a strong opinion for or against these pipes?
I am considering a set. I have no stink issues, I just am interested in what people's experience is with instalation, sound and PCIII maps with it.
Yosh is top shelf stuff.
Excellent workmanship and fit.
You can't go wrong with Yosh.
The OEM heat shields fit on perfectly, and new cans don't need extra shielding on the body.
My TRSs go back some years, and at the time, the Yosh was a quieter can, and likely still are is my guess.
They are not loud at small throttle openings, in fact quite quiet in my "around town mode" but they sure do sing loud when at high power levels like track days.
Like any straight through packed design, the packing life is not infinite, and not only does the noise go up, so does the can skin temp.
I went stainless steel at the time.
IF it was today, I would at least consider going Titanium, purely as a can skin temp reducing element.
I'm no fan of carbon for cans, unless one has $$$ to replace crash damage that metal cans only need a hammer for.
And stay away from carbon cans if you know you won't repack when it's needed, as the C F will cook out.
There's also some excellent PC maps in the WT Dropbox.
