They fit on mine. If your pipes fit on the stock y-pipe you will have no problems.

Oh, BTW, I think the y-pipe was one of the best bang for the buck performance mod's I've done.

heres my Akrapovic Y pipe with GYTR slip ons, they fit with the same OEM muffler gaskets as stock, so if the Yoshis dont use the gaskets, they won't with the Akra ...Akra is the same diameter outlet as the cat, so I would bet 99% no problem.....

I'm looking at buying the Akra y-pipe. Are you able to screw in the 02 sensor in the Akra y-pipe, or do you have to get used to an engine code going off once installed?
Yes, you can screw in the sensor. If your running a PC or any other FI module, just leave the screw in the Y pipe, the stock 02 sensor will screw with the PC mapping so leave the 02 sensor out.....

I have the Dobeck Fastcard, no 02 sensor, and Akra Y pipe with GYTR slip ons, runs great...also running forum member MRGRN's custom CF heat shield, screws right into Akra or stock Y pipe....

all the stock 02 sensor does is lean the mixture out for emissions....if you take it out even with no PC it will be fine, if you plan on putting a FI module soon, just leave the screw in there, cause it's already safety wired

Thanks bmack. Everything is stock now. I plan on just modifying my silencer with a baffle kit and getting the y-pipe and most likely a power commander. These will be xmas gifts, so i have to wait and see how it all works out.

Isn't the Y pipe the same dimensions as stock, without the cats? If so, any slip on should fit.....right?
