Hi,

I have a 90 Pontiac Firebird Formula with stock dual exhaust & dual cat. There are some holes in the pipes before the cat, and I am looking for a replacement, but can't find one online.

Does anybody know how to fix this? Do i need to get a replacement or is this something that needs to be custom made?

Some pictures












Thank you!

 

Magnaflow makes a replacement.

Looks like the factory cats are looong gone.
As said above, that looks like a good replacement

And those aren't holes, its just the carbon rusting little pits on the surface.

 

Thanks friends! I have been looking for a while and could not find it.

 

Thanks Paul, do you think there is an equivalent for California?

 

Um, use the website? there's a link to the Ca catalog on that page, if the car listed in your description is right then: http://www.magnaflow.com/02catalytic...&splityear=PRE

 

Thanks yes, I actually found it right after my last post

It's part number 332479

 

I can get that exhaust to your door at a discount compared to everywhere else.

PM me if you are interested.
