Proper Stainless T304 Exhaust system?

I swapped out my lower bank catalytic converter 3 years ago, magnaflow. It is not holding up well to the road salt even with constant washes. I now need to swap out my upper cat due to a pin hole leak. Anyone know of a good source for exhaust components made with T-304 stainless steel?

 

Highly doubt anyone makes direct fit/OEM replacement cats out of 304 for our 21+ year old trucks. However if you can fabricate/weld the flanges, sensor bungs, etc that are needed, there are lots of options:

Excellent Site!

thanks for sharing

man I’m old
Just bc I was looking thru old invoices yesterday for my 1owner Subaru RSTi…..bought a 3” high flow cat for $86…….20yrs ago

those resonators look good and reasonably priced

 

Ace Race is an excellent resource and for us WA guys, local too. Even though an exhaust isn't specifically made of 304 for these trucks, it's a pretty simple system to build yourself. Mine took us maybe 2 days of half ass working on it between other projects.
