I remember reading somewhere that X-Pipe is more for performance gains where as H-Pipe is more for sound.
over on the mustangforums the X's produce more power whereas the H's produce better sound quality.
I think it depends on what you want, sound or performance.

Some times there is no performance difference between the two, but either one is usually better than nothing.
When there is a performance difference between the two, the X is usually better.
There is a big difference in sound between an X vs H though.
The sound is how I would recomend that you decide what you want, but like mufflers opinions vary on what sounds the best.

the x-pipe will always have equal pressure on both sides and the h-pipe will not

im guessing that they will only trip about it if they look under.... and if they even know that the car was suppose to have a Y pipe insted of duals (most of the time they dont know). As long you have the cats thats all they care about.

Now that would seem much more sensible but it sounds like you need to get someone who does not know the correct configuration (which would seem much more unlikely as the cars get older) OR you can "work" with, if you know what I mean!

Always like to hear about real world experience rather than theory. What year was/is your car, which engine, and exhaust specifics such as headers, stock exhaust manifolds, duals, mufflers, etc and which pipe was better (X, H) and sound differences? Thanx.

I'm pretty sure their computers inform them of the correct configuration elsewise they would be unable to properly test/inspect the car.
None of this is to say that you will never get away with it, but its a bit of an investment to make on the chance that they wont catch it, and who knows what the ramifications of failing could be...
One other option is to keep your existing factory exhaust and every two years swap it with the performance exhaust for smogging purposes...you risk being picked up by a roadside emissions testing machine but to be honest, in nearly 50 years in california I've only seen one ever placed in san diego (2nd largest CA city) and that was like 8 years ago so I dont think you should really worry about that.
