WTB: 3 inch cat

I am looking for a 3 inch cat, gutted cat or even a test pipe.
So long that it’s 3 inch , do not care if it has flanges or not (my exhaust is custom so it won’t line up anyway)
I realize that I am killing my high flow cat on my car right now when I go to the track.
I need something that I can use to substitute my cat during upcoming track evens.

thank you , PM as always.

i has’m in stock, 3" resonated test pipes with flanges.
