So I'm interested in getting an aftermarket header for my frs but I have a few questions.

My first concern is that when I look up headers for my frs they say that they are for off-road use only. Why is this? Will I risk the chance of getting pulled over and ticketed because of an aftermarket header?

Also, are there any concerns with the reliability of aftermarket headers? Will I have to worry about anything breaking down?

I'd ultimately like to get a header and an open flash tablet to increase my horsepower. Are there any other problems that could come with installing an aftermarket header? Thanks!
