You might want to check with the regulations in Kali. They are very strict on items such as longtubes. It's a federal crime to remove a functioning cat and replace it with something else. More than likely if you get the headers you will have to remove them for the yearly inspection and put on the stock manifolds to pass. To get the most power out of the headers you will need a better flowing catback than your stock one. I would suggest going with the TSP Catted Y pipe along with your Pacesetter headers. The catback is up to you as everyone has their personal preference. HTH

You need to make sure the headers have a C.A.R.B EO number. That means they are legal in Cali.

Don't live there anymore, so not sure if there are cali legal headers. If you can find a set that is, just get a catted Y pipe, and get a good tune, you should be able to pass inspection. You might want to post this in the Cali section of this board too.
