Normal steel bolts will non removable in a year or 2.

So this I how I fix these cat back exhaust issues:

1.) I buy a replacement rear cat exhaust hanger.
I cut the nuts off and use stainless steel bolts and
nuts with washers so they don't rot up and can be
removed again.

2) If the flange on the cat is rough. I use new oem
gaskets with permatex ultra copper maximum temperature
rtv gasket maker to help the flanges reseal with the new
gasket.

3.) Then I use Northern Stainless exhaust because
Toyota OEM exhaust are insane. Walker only last 4 to
5 years in my environment then they rot off.

These two rear portion, even in the top quality walker, rot off in about 4 years here also. I'll keep that in my favorite and hope they will still be making them when I'm again having to replace this exhaust.

Here are pics of it now after being exposed to some nasty mag chloride brine. As you can see, there are flash rust speckles on it, which kind of surprised me. I am not aware of the grade stainless steel used, but am curious now. (Brillo76 any idea?) I plan to wash it off thoroughly this week along with the underbody. The rust spots do come easy with a damp towel.

However, if you have toyota replace your shocks, struts or exhaust. They will lifetime warranty it as long as you own that rig.. So if the price tag is worth it to the owners. That's an option too. I just can't bring myself to pay that cost of a complete exhaust :O
