I know I've brought this up before, but not having dual exhaust is killing me.

I really need to know some facts from people who've done this.

I've got an '04 GT, 600 miles on it.

I plan on getting a CAI and dropping the car a bit.
But to me the duals are very important.
So here are the q's.....

Will this change the performance of the car for the better or worse(turbo backflow issues have been brought up)?
Which one should I get from a performance/reputation standpoint(BTG, Borla, or what)?
Is the 2.5" diameter large enough?
Will the exhaust exit each pipe at a similar rate?
Does it sound like a V8 (ideal) or is it a bit too ricey?
How do I make a cut out for the right side exhaust to sit?
Do I do this myself or take it to a specialty exhaust shop?
Most importantly, where can I see photos of someone's GT with duals.

Any info is appreciated! Thanks.
