Any noticeable power/torque gains anyone?
Want to do it this weekend but is it worth it?

I would guess that it is not worth any measurable power on a street driven car.
Track only/custom built engine maybe, but no on a mostly factory car.

There might be some gain in a long run. Since the hot exhaust gases are not travelling through the manifold means the intake manifold is getting as hot. EGR isn't open all the time it opens up depending on rpm the throttle input.

It will give you some power, but its very minimal. Someone told me that it was like 2 horsepower

On my butt dyno, I feel no gain. I would leave it alone unless you're tripping a CEL.
