I've got a set of LS Cats if someone is interested.

1973-1974 was when they started installing cats on vehicles right during the gas crunch era. In texas and I got this from the DMV if it was not installed as a factory item it does not need to be present on the vehicle at the time of inspection. So if it is 78 for sure or newer at least one set of cats has to be in place on the vehicle. Went through this with the inspections station on my pontiac firebird. They did check to make sure that all required vacum lines were in place on the engine. What few there were lol. Working on getting that car back through inspection for the year having some brake issues that are holding me back atm. Sean
