Re: Looking for some advice.
The fact that it is a CA-emissions car really has nothing to do with what you can do in MD. The problem with long tubes is "Federal" law. Federal law prohibits 1) changing the number of cats; 2) relocating the cats; or 3) replacing a cat unless is is certified defective. But, not all states or locations enforce the Federal laws.
I'm a bit surprised your 95 is even listed as "CA-emissions". The 95 auto trans cars got dual cats in CA, and required purchase of the CA-emissions package. The 95 manual trans cars were 50-state certified, and I don't believe they got dual cats. I was living in CA in 1995, and followed the 95's fairly closely, since I had just bought my 94.
In MD, they will enforce MD regulations. If they don't do a visual inspection, you can run long tubes with dual exhaust and dual cats, or with a single exhaust (Y-pipe/catback) with a single cat. There is nothing inherent in long tubes that prevent you from passing a tailpipe test, as long as you have a cat, and the engine it running properly, and not highly modified. How big a cam you can use and get by with a tailpipe test will be determined by the skills of the cam designer, the the skills of the tuner.
I'm sort of surprised you jumped to the conclusion that you need a "rebuild" based on "a slight ticking sound". Did your mechanic clarify his thinking?

I dont necessarily need a rebuild quite yet but the ticking was really bothering me and it gives me an excuse to rebuild.
My mechanic said the car will run fine with the ticking, but not to rag on it and Ill be fine.
I however would like to know that when I stand on the pedal I wont have to worry, also the car has 180,000 miles so it in need of a rebuild soon as well.
I have tried engine restorers and other method to relieve the ticking to no avail.
I was told my car was a cali emissions car, but Im not 100% sure.
Is there a way to tell?

There should be an emission label on the driver's door.
Also, it will have RPO code "NB6" - Emission System, California Requirements, Tier 1, on the build parts tag (glove box or end of driver's door).
