Of course..granted some of these cars have 2 O2 sensors...I'm just asking why sacrifice performance when you can find a better more protected location for a sensor...
Chances are a customer isn't going to be to concerned with Federal Emissions standards...if they buy a GP, means the wanna move.
I understand the need for O2 sensors and the mechanical implications

There was absolutely no need for the 02 sensor to be on the top of the pipe at all. In the high flow downpipes that are available they put the 02 sensor in the side of the pipe, which is just fine unless there is something flying around under your car thats gonna hit it. And if anyone has noticed, the '04 GP has the exact same exhaust setup as the '97-03'*, EXCEPT it has no u-bend.

But on the street, it probably won't make much difference.

There never was a U-bend on my exhaust. The original exhaust manifold does not exist direct center, so the original downpipe has about a 2" offset, but it is straight from the Cat to the resonator. The O2 sensor is located horizontal just before the resonator. After the resonator the 2 1/4" pipe jogs slightly around the fuel tank but far less than in a GTP.
The new TOG headers are dead center. A real straight shot. The new downpipe flex joint is a full 3" diameter instead of the original flex that is only 2" inside diameter.
