2G Restoring exhaust (high flow cat info)

[rambow70]

So I am rebuilding my car to spec/close to it. Well my original exhaust is all rusty, has holes, and is about to break in half! I know a great local shop with fantastic quality and prices to do the work. However, I can't seem to find much info on stock exhausts because everyone 3inch straight pipes them!

I was wondering how many cats are in the car? Pre and post?

Also if there is only a cat after the turbo down pipe I was thinking about getting a high flow cat and have all the stock sized piping running to the factory muffler which I will polish up! I will probably delete the resonator because it looks bad ha but hopefully the cat and the muffler quiet her down a bit!

Thoughts on this guys? And yea how many cats and where are they?

1 cat before the secondary o2 sensor underneath the car. Stock piping size is 2.25"
