Hello,

I need to install a new Y-pipe in my exhaust.
The bolts are completely oxidized and even with a breaker bar they don't move.
I have (4) bolts, (2) on each side.
Any ideas on how to do this?

The best solution I've found for header bolts is heat.

Another to consider, is "PB Blaster" Penetrating Lubricant from any Auto Parts store. Like WD-40, but seems much better at soaking into rusty stuff.

Heat them red hot and they will break loose. Done it many times before.

this and let it soak for more than 5 mins... a good breaker bar afterwards..should be good to go..

If that dont work and you dont have access to a torch or worse - you stripped them... Angle grinder does wonders
