Import Exhaust Systems?

I have a 2008 civic coupe that i wanted to add a custom exhaust to. I just bought a Apexi N1 Universal muffler because i am worried about Massachusetts Laws against noise polution or discrimination towards loud imports.

Anyways, Would the Apexi N1 Catback system have been better than the universal muffler being taken to the shop and having a 2 1/4" custom pipe installed from the Cat back? I'd say it would be no different, right?
Another question, How much different would the 2 1/4" pipe make from the cat back rather than leaving the stock pipe in and just adding the N1 Muffler?

I would add a high flow cat but im afraid it wont pass emissions?
I would also add a Header but im afraid that wont pass emissions?
Doing a complete custom exhaust system would cause nothing but problems with emissions and the police, right?

I want to do it up but i want to know what would be the best setup that I could get away with and still pass emissions.

Can anyone Help?

At most exhaust shops the Crush bend the pipe which is no good, it creates disturbances in the exhaust flow, where as a full apexi N1 is mandrel bent, and is MUCH better.

you can add a high flow cat, and a header and still pass emissions, I'm from california, and emissions laws here are incredibly strict, and I can use a high flow cat/header/full exhaust on my del sol, and have it still be legal. If you really want to be overly specific about it
get a DC Header, they make carb legal headers, as said high flow cats will pass fine, and anything after the cat is legal in terms of restrictions ie: resonators / no resonators, or any muffler at all. The only law for an exhaust (past cat) are sound laws. to which you can just get a silencer for it at be fine.
