Socal sr20det ticket help!!!!!!

[240Cali]

So I have read a lot about this but a lot of the stuff i found is from a good 3-4 years back... simple, I got pulled over in La habra cop asked if i had an sr he poped my hood took sum pictures and told me to call the number in the back of the ticket to set up an appointment to have a reF test my car to see if it would pass smog.. now im down to pay ANYTHING i need to pay without having to swap to a KA .. Ive heard its as easy as just calling and paying? so do I not have to go to the ref if i pay? would a lawyer help me at all? This happened last night and I'm freaking out this S14 is my DD ANYYY help or info would be greatly appreciated.. thank you
