I am in the middle of installing my ws y pipe and have everything loose but the back two bolts which are welded on with rust. I have soaked it with lots of liquid wrench but it has not helped. Can anyone offer any suggestions?? I don't want to have to re install my stock one and wait so any help will be great!!

 

I assume you mean the two bolts going to the Catalytic converter. Here in Wisconsin its pretty common to have to cut them off with a grider/cut-off wheel. The last two y-pipes i replaced I did the CAT at the same time and the two bolts down stream of the cat aren't so bad usually.

Good luck,
JB

 

Try heating them up really good, I had to cut mine also, they just wouldn't come out.
