Thats not what worries people. its the fast that when you go and get an inspection they make you take it off.. Cops (in dallas at least) dont care if you have it. Because they know you will have to scrap it for inspection.
If you want to do it yourself, i can give you all the info. its very simple, and will cost you less then 60 bucks and maybe 2 hours of your time.
If you ever come up to the Dallas area my buddy at Bonnie and clydes does an amazing job.
