headers question
i plan on purchasing LT headers with high flow cats soon..il be running this sytem with my borla straight pipes..
after installing the system will i NEED to get a tune right away? im kinda short on money and saving up for the headers, so can i get away with not getting a tune for a while or will my car run like garbage without a tune?

If it's just more noise you desire, and saving a couple of $$, I understand running no cats. If your think it will precipitate a significant HP increase...don't bother.

Considering you have zero mods, I would not get distracted with how back pressure(or lack there of) impacts performance. Again, because you have no mods, the difference between running cats v/s no cats won't be noticed(except for the noise and smell). Additionally, I can only surmise that because funds are tight, that you won't be getting a tune any time soon.....so the full potential of the added headers will not be realized anyway.

For the post '96 vehicles, don't they still do the test by plugging in the OBDII?
Remember how they would actually run your car on the simulator at various speeds? I think for vehicles '95 and before, if it passed sometime within the last couple of years, it would be exempt from emissions testing as long as you own the vehicle, right?
But bolting on headers shouldn't cause a code, should it?
I'm in OK now, no emissions here!
