I was cleaning up the attic today, I have a set of cats from the stock header flange back through the flex joint 90 degree to the mufflers into the side mufflers.
Mufflers not included.

I am assuming they are high flow from corsa as they were taken off a corsa exhaust, they are 3"

So looking at these a little closer it doesn't look like the elbows are 3" sort of looks like a stock set with 3" hiflows added.

Open to offers, Actually open to someone letting me know what they are worth. :)

If anyone makes me a reasonable offer? Otherwise I'll pack them away for the next 10 years...
