Cat question?

[N8nSM]

First off, thank you again to all that responded in regards to the Z dying after entering open loop. It was the fuel pump (andtuel pressure regulartor as I found also). I've got all that replaced now and back together. I'm still trouble shooting a high idle problem (idling at 3k when started).


At any rate, I've got the Corsa exhaust that is ready to go on one I figure out the idle problem. I was thinking about adding a set of high flow cats but it looks like the cats are connected directly tot he exhuast manifolds. What's the best way to replace these and what part numbers do you have? Do I cut the cats at the exhaust manifolds and weld back in place? What's the best procedure for this?

Thank you all,
