I have been wanting to do a Downpipe, Intake, Exhaust, high flo cat. My concern is the legal issues that could come with these. I am new to the moding scene so I really don't know what all can happen to you for each of these mods.
Is it worth it? What all can happen if you have a cop that feels its your turn to be pulled over and inspected? Do you need all these parts to see a decent HP gain or will just a few of them do? Anything you guys can tell me would be a huge help.
Thanks in advance,
