Anyone got any clue where I could find a dyno comparrison for a stock xb to an xb with a Greddy Evo 2 exhaust?

None of the axlebacks really add much power. I'd be surprised if you found much difference. I'd say the main criteria for an exhaust are sound and appearance...

You might be right.........then again, you might be wrong.

I was taking a mpg reading with every tank I ran through the box since new. My numbers never changed.

As soon as I put on the TRD muffler, my mileage went up at least 2 mpg. Now I'm up to a consistant 33. I've only ran about 4 or 5 tank fulls since then, but it is up, no less.

So, if my mileage is up, efficiency of the engine is up. Is the power increased? I'm not sure, but to guess, I'd say yes.

I said "much power". Yes, they may be an improvement to the stock exhaust, but I doubt you'd see much difference from one aftermarket axleback to another...
