just saw that my exhaust is split in half(vance and hines) was making a loud noise lately thats probably where it was coming from. thread showing down the middle of my rear tire, and i need a front tire.....man it keeps getting worse. key wont turn at all. for the past few days it would take about 5 min for the key to turn.. then 15. then 30 min. today it still hard to turn.
