Full exhaust system reliability

[mrninja9]

man i dont even have mine modded out yet and for some reason i go through tires maybe the sprockets i put on hmm oh well

Just curious, but is a map required with only a full exhaust?  I bought my bike with a full Yoshi, but the guy had no PC3 on it.  Should I get it?  TIA!

they might have tuned it with a yosh box.

I don't think it was tuned with a Yoshi box. Guy told me that it was a waste of $300 and I wouldn't get anything outta it. I'm kinda thinking it'd be a good idea reguardless since most everyone on this board with full exhaust has one already.

Do you suggest PC3 or Yoshi box?
