We all gotta start somewhere. Don't let the fear of asking make you ignorant.
evopanop is right about the tp. Check your own laws for the legality though, I hope you don't live in Cali lol. If you do have emissions testing in your state, just bolt on the tp but keep your cat and when you have to go in for testing, replace the tp with the cat. It's a fairly easy switch and the tp is well worth the little $$ it costs.
