Default TPIS Header Question

To emissions or not to emissions. Does it make sense to to order them with or without the emissions. Also If I get them without do I need to do anything special so the car does not throw a code. Also I am running a 2.25 cat back and was thinking about getting their 3" system any comments on this system. I did a search and found very little about it.

The EM's I ordered came ready for the O2 sensors. The EGR threads were there but holes had to be drilled to make it functional. I decided to leave the EGR holes plugged and delete the EGR system. If I ever want to put it back I can drill the holes out and reinstall all the EGR stuff. Not sure if that helps any. What year car do you have?

With or W/O emissions depends on your location which we don't know. Also, are we talking L98 or LTx? You'll need the O2 bung(s) no matter what, unless you're going carbed. But those should be included in either set.

If you get non-emissions, you must close the EGR port on the manifold with a blockoff plate, and have the chip reprogrammed to delete it.

You can either leave the AIR pump on or not, but I would disconnect its electronics. You would need an eliminator pulley to delete all of it, pump and all. It does not need the chip changed, just take it off.

Pick catbacks based on sound preference alone, everything else (size or flow) is secondary. I have not heard their catback yet.
