Just Installed my New Exhaust

I just got done installing my new 4" cat back MBRP after taking the factory exhaust off. Before the new exhaust was installed, with my S&B airintake and Edge EZ on high, I could make the tires squeal from the full stop. Now I can't do that anymore and it seems I have lost some low end power. Any suggestions?

A side note, it sounds perfect and the transmission seems to shift a little smoother which I was surprised with.

I think the top end feels about the same.

Well less backpressure equals less low end torque.

most likely yes, b/c that would create some back pressure....
