What else Do I NEed?
Planning on Buying Corsa Cat-Back, Pacetters LT, and TSP's Catted Y.....do I need the O2 extensions as well?
What do I absolutly need to finish the setup? Gaskets? I want this to go as smooth as possible. Unbolt and bolt on but want everyting ahead of time before I start tearing into the car.
Thanks!
