True Duels W/ x-pipe?
Ok, so I got a burr up my *** and decide I wanted true duels. Now the only way this would work would be to use an x-pipe so the o2 sensor would still read both front and rear banks(put it in place of the y-pipe). So I called Nice at DT and ran this by him and he doesn't think it would be an issue to do this. So my question to you guys is would any of you guys have any interest in this? I don't have any other details other then what I have told you. BuickRacer is taking his car in sometime next week I guess to have his headers installed Nice said he would look at it then to see what would have to be done.
I think it would be Bad *** to see a W-Body with duel side exit exhaust just a thought!!

So you are looking at drilling/tapping the center of an X-pipe, building a section to link each manifold pipe to the X-pipe, then keeping dual pipes aft of it (obviously ditching the catalytic converter as it won't fit, plus you will be one short). Putting two (again, obviously) smaller pipes in the place where the single pipe/converter sat. If you can make it work, I would expect you to see a bit more low end torque and choking off your top end pretty substantially from the smaller diameter pipes. Your car, your choices, just makes no sense to me going that route.

So what you're talking about is not having the two "banks" collect/merge into one?
EDIT:
So you're hoping Doug Thorley would just make a custom "collector" piece? Is there even enough space to run duals down the back?

I don't think it would cost too much. You could run it out the back or out the side which would be F%$#in sweet I think. If you did it out the side you could use this muffler http://www.jegs.com/i/Magnaflow/642/11378/10002/-1
Which would cut on cost a bit.

Maybe, maybe not but,...
I was looking at this area before the collector, you can cut the collector and run duals from here but I think they would have to be very close together as it travels to the rear! or else the left would hang so low!!

That’s what people said about the F-body’s but I have seen people with true duals on them. Its call imagination and that doesn’t always mean a **** load of money. If no one wants to go in on this that’s fine, but there’s no need to bash me for asking.

Here look at this. This is on a 97 - 03 Grand Prix but certainly should work for 04+ since a 97 - 03 cat-back will fit on the 04+ Grand Prix by adding another hanger iirc.

You are incorrect sir. If anything you would gain top end and lose bottom end. If it were an h-pipe you would lose top end and gain bottom end, and how can you say the going from a single 3 inch to duel 2.5 inch would be restrictive? That sir makes no sense. Duel 2.5 inch would be like running 5 inch.
