Cat / Exhaust Replace Need Help

Hey all.

Replacing both Cats and New exhaust. Problem is having hard time breaking these nuts. Which are not too rusted out..

Does anyone know. Is this a stud with just nuts and washer?

Not sure why the star is on the bottom of it.

Any ideas on how I can break these 3 nuts loose? 14mm

If I can break these 3 loose, i can avoid having to mess with the rest of the exhaust and other Cat. This is the first cat coming from the headers.

Any advice?

I put PB blaster on it. They dont look too rusted, and tried a small impact already. About to get the breaker bar and a long extension.




Thanks again!

 

They are going to break. Knock out the stud and just put a bolt with a nut and washer. If you can't get the stud out you might have to drill them out big enough to put a bolt in there

 

Can you unplug o2 sensor and unbolt cat and just remove it from the truck? Might help with using an impact gun to remove the nuts.

 

GOT IT!!! Thanks guy!

 

What lift?

 

Its a Fabtech 6' drop bracket.
