How is the exhaust bypass done?

The stock set up involves a single pipe going into a rear can and exiting via 2 tips (repeat on the other side). If one were to keep the stock tips, but throw out the rear muffler, somebody would need to fabricate a 1 into 2 Y splittler, no?
If someone had this done, can this Y be obtained? I can have someone do the cutting and welding here. The fabrication part would probably be the tricky part.
I am in northern california.

Thanks in advance

I had mine done at dealer

I had this done by the dealer (Maserati of SF) when I bought the car. They removed the muffler and put in straight pipes from the catalytic converter. The chrome tips are slightly larger than stock.
They might be able to point you somewhere to have this done.
Good luck, it will sound awesome.

I take it no backfiring, lack of backpressure problems? (on the car)

Well, not backfiring, but...

First, I know there is some basic science here that says that backpressure is good in the right balance to optimize engine power. That said, I don't really know how the system was designed on my car, although I'll ask the dealership.
Here is how it behaves:
- On acceleration it is smooth and sounds awesome. As far as I can tell there is no power impact one way or the other, but to be honest, when getting on the accelerator and winding out the gears, I wouldn't notice a 5-10% difference in either direction. And it usually blows my passengers away.
- On downshifting and using engine compression to decelerate, which I do most of the time, it makes an impressive 'gurgling' sound, but not a sharp backfiring sound.
Maybe my wife is right. I just like the sound (and of course, she hates it).

Ansa makes a great dual stainless resonator tip. I had a set fabricated at a local muffler shop for under $500. The car performs the same but sounds incredible. I've posted a wav file of my Spyder on Ferrarichat.com uder Other Italian. I can't get a wav file to post here.
Here's the URL for the Ansa tips (model 7818).
