You could get some catted or uncatted connector pipes. Or if you wanted to go back to stock, you could find someone who put headers on and still has their OEM cats.'05 CTS-V, Maggie, Kooks, Hotchkis, Ground Control, Corsa, B&M, DSS/Hendrix, Full 3M Clear Bra, Autovation, V Headrests, CTS Console, STS-V 55w Fogs, Black Vette FRCs, Specter Werkes, Katech LS9 Clutch, SS Brake Lines, Heavymetals U-Turn Fuel Line Eliminator, Momo Combat Evo Shift Knob, Wldwhl Clear Sidemarkers, Linea Corse LC855 Wheels, plus a couple more. Mustang dyno'd at 472 RWHP/411 RWTQ.

I have a set of stock cats, they're worth $150ish each at the scrap yard, but I hung on to them in case someone else needed them. They were pulled from the car by the PO at 36K, based on the receipt for the headers that are on there now.

What I want to do is knock my cats out, run my manifolds,What do I need to do ,unhook the rear oxy sensors,will this mess anything up?can a hand held tuner tune this combo? as I don't have anywhere around to tune

I would not use a hand-held tuner to accomodate modifications. If you are not close to a tuner try a mail order tuner such as Wait4me tunes. A mail-order tuner can, among other things, turn off the rear O2 sensors, which most folks leave in place to pass visual state inspections.

While I would suggest a mail order tune, Good luck trying to get a wait4me tune. I sat here and LS1tech, PMed and emailed for months prior to just going and getting a legit dyno tune from TuneTime in NJ. If you have to chase someone down to GIVE them your money, sometimes its not worth the headache.
