It was the lable that says TI-4... I called PC and they said it sounds like it's time to repack the muffler... I only have 10hrs on the new exhaust system but he said that would be one reason it's running hotter...

I'm still confussed... nope it's not backfiring and nope I'm not sputtering the bike rips... I thought about repacking but my buddy (mechanic and mmi grad) told me it would be a waste of my time b/c the pipe has like 4 hrs on it...

:confused:

Dunno guys? got some new stickers from PC and I'm going riding :lol:
