due to scraping since 2003, my Y pipe is pretty banged up... should I be concerned at all? I'm not lowered at all, stock all around suspension wise, but will I need a new Y pipe? I was told the HR Z y pipe is a great replacement, but I dont want to replace it right now if i dont have to.

 

Looks fine to me

 

any leaks in the damage areas? If not you should be good to go for now. The problem you may have later is rust forming in those areas

how did that happen going into a driveway or over a speed bump?

If you get another pipe the same thing will likely happen to that one if it's some where you go regularly.

 

speed bumps on my old military base, there was a road that had this one HUGE speed bump. but since it was the only route out of the area, after a few weeks of constant complaints I got it extended so not nearly as much scraping going on now but I just saw that when I was doing my Big 3 upgrade and it worried be a bit.

 

You're fine until that corrugated tubing busts. The braided material is just a cover.
